Magic Quadrant for Web Application Firewalls 17 June 2014 ID:G0*******Analyst(s): Jeremy D'Hoinne, Adam Hils, Greg Young, Joseph FeimanVIEW SUMMARYThe WAF market is growing quickly from a small base; it is composed of pure players, application delivery controller vendors, cloud service providers and network security vendors. Buyers should evaluate how WAFs can provide high security, minimize false positives and sustain performance. Market Definition/DescriptionThe Web application firewall (WAF) market is defined by a customer's need to protect internal and public Web applications when they are deployed locally (on-premises) or remotely (hosted, "cloud" or "as a service"). WAFs are deployed in front of Web servers to protect Web applications against hackers' attacks, to monitor access to Web applications, and to collect access logs for compliance/auditing and analytics. WAFs are most often deployed in-line, as a reverse proxy, because historically it was the only way to perform some in-depth inspections. Other deployment modes exist, such as transparent proxy, bridge mode, or the WAF being positioned out of band (OOB) and, therefore, working on a copy of the network traffic.The primary WAF benefit is providing protection for custom Web applications that would otherwise go unprotected by other technologies that guard only against known exploits and prevent vulnerabilities in off-the-shelf Web application software (see "Web Application Firewalls Are Worth the Investment for Enterprises").WAFs also integrate with other network security technology, such as vulnerability scanners, distributed denial of service (DDoS) protection appliances, Web fraud detection and database security solutions. In addition, WAFs sometimes include performance acceleration, including content caching, and might be packaged with Web access management (WAM) modules to include authentication features — notably to provide single sign-on (SSO) for legacy or distributed Web applications.Gartner estimates that the WAF market grew in 2013 at a rate of approximately 30% from $259 million to $337 million, and most of the growth was driven by a handful of vendors. Demand in North America has been strong, with 45% of the total market. EMEA accounts for 29% of the market, whileAsia/Pacific accounts for 26%. The Middle East demonstrated the highest growth rate, while Europe was the least dynamic region.To be considered for this Magic Quadrant, vendors must actively sell and market WAF technology toend-user organizations. The technology should include protection techniques that have been designed for Web security, beyond signatures that can be found in next-generation firewalls and intrusion prevention systems (IPSs). WAF products should support single and multiple Web server deployments. This Magic Quadrant includes WAFs that are deployed in front of Web applications and are not integrated directly on Web servers. This includes:Purpose-built physical, virtual or software appliances provided by pure players or network security vendorsWAF modules embedded in application delivery controllers (ADCs; see "Magic Quadrant forApplication Delivery Controllers")Cloud servicesHow WAFs integrate other network security technologies — like static application security testing and dynamic application security testing (DAST) or security information and event management (SIEM) — is often one of the indicators that reflect a strong presence in the enterprise market. Consolidation of WAFs with other technologies, like ADCs or anti-DDoS cloud services, brings its own benefits and challenges, but this market evaluation primarily focuses on the buyer's security needs when it comes to application security. This notably includes how WAF technology:Maximizes the detection and catch rate for known and unknown threatsMinimizes false alerts (false positives) and adapts to continually evolving Web applicationsEnsures broader adoption through ease of use and minimal performance impactIn particular, Gartner scrutinizes these features and innovations for their ability to improve Web application security beyond what a next-generation firewall, IPS or open-source WAFs — which are available for free (such as ModSecurity and IronBee) — would do.Return to TopMagic QuadrantFigure 1. Magic Quadrant for Web Application Firewalls STRATEGIC PLANNING ASSUMPTIONSAt the end of 2018, less than 20% of enterprises will rely only on firewalls or intrusion prevention systems to protect their Web applications — down from 40% today.By year-end 2020, more than 50% of public Web applications protected by a WAF will use WAFs delivered as a cloud service or Internet-hosted virtual appliance — up from less than 10% today.EVIDENCE1"Payment Card Industry (PCI) Data SecurityStandard:Requirements and Security Assessment Procedures, Version 1.2," October 2008; and "PCI Security Standards Council — Information Supplement: Application Reviews and Web ApplicationFirewalls Clarified, Version 1.2" October 2008NOTE 1TYPE A, B AND C ENTERPRISESEnterprises vary in their aggressiveness and risk-taking characteristics:Type A enterprises seek the newest securitytechnologies and concepts, tolerate procurementfailure, and are willing to invest for innovation that might deliver lead time against their competition.This is the "lean forward" or aggressive securityposture. For Type A enterprises, technology iscrucial to business success; of course, they alsohave skilled and dedicated security teams.Type B enterprises are "middle of the road." They are neither first nor last to bring in a newtechnology or concept. For Type B enterprises,technology is important to the business andsecurity teams are often understaffed.Type C enterprises are risk-averse forprocurement, perhaps investment-challenged and willing to cede innovation to others. They wait, let others work out the nuances and then leverage the lessons learned. This is the "lean back" securityposture that is more accustomed to monitoringrather than blocking. For Type C enterprises,technology is critical to the business and is clearlya supporting function. These enterprises might nothave dedicated security teams.EVALUATION CRITERIA DEFINITIONSAbility to ExecuteProduct/Service: Core goods and services offered by the vendor for the defined market. This includes current product/service capabilities, quality, feature sets, skills and so on, whether offered natively or through OEM agreements/partnerships as defined in the market definition and detailed in the subcriteria.Overall Viability: Viability includes an assessment of the overall organization's financial health, the financial and practical success of the business unit, and the likelihood that the individual business unit will continue investing in the product, will continue offering the product and will advance the state of the art within the organization's portfolio of products.Sales Execution/Pricing: The vendor's capabilities in all presales activities and the structure that supports them. This includes deal management, pricing and negotiation, presales support, and the overall effectiveness of the sales channel.Market Responsiveness/Record: Ability to respond, change direction, be flexible and achieve competitive success as opportunities develop, competitors act, customer needs evolve and market dynamics change. This criterion also considers the vendor's history of responsiveness.Marketing Execution: The clarity, quality, creativity and efficacy of programs designed to deliver the organization's message to influence the market, promote the brand and business, increase awarenessSource: Gartner (June 2014)Return to TopVendor Strengths and CautionsAdNovumSwitzerland-based AdNovum is a long-established provider of application development, IT and security services. It recently started its expansion beyond this home market, and had its first successes in Singapore. AdNovum's product offering, under the cover name Nevis Security and Compliance Suite, includes WAF (nevisProxy), authentication, identity management and document signing, and was first shipped in 1997. The nevisProxy WAF is delivered as a software appliance and does not yet have third-party evaluations, but provides some features beyond signatures with support for a positive security model, URL encryption and protection against cross-site request forgery (CSRF).Swiss enterprise buyers in need of a combined WAM and WAF solution to protect custom application should consider AdNovum in their competitive shortlists.StrengthsAdNovum has proven experience with large financial institutions in Switzerland, and is able to quickly develop to specific customer requirements.Nevis Suite includes robust authentication and SSO features. Its centralized management("nevisAdmin") supports a large number of WAF instances, and is multitenancy-capable.AdNovum provides free licensing for test servers and unlimited flat-rate agreements for very large deals.CautionsAdNovum's WAF is one component of a software suite that serves primarily WAM purposes;consequently, the R&D investment in pure WAF development is more limited.AdNovum does not appear on Gartner customer shortlists for WAF outside of Switzerland.AdNovum lacks hardware appliance offerings that many of its competitors provide.Protections against SQL injection and cross-site scripting (XSS) are focused primarily onModSecurity open-source signatures, with no complementary internal or third-party threatresearch.nevisProxy does not offer virtual patching based on the results of a vulnerability scanner, ordedicated security and compliance reports.Return to TopAkamaiAkamai (AKAM) is based in Cambridge, Massachusetts, and provides a leading content delivery network (CDN). Its network and security cloud services, including its WAF (Kona Site Defender), are built on top of the Akamai Intelligent Platform, its global cloud infrastructure. The Kona WAF has been available since 2009, and received significant improvement in 2013. The Kona WAF management and monitoring consoles (Luna Control Center and Security Monitor) are also delivered as Web portals.Akamai's WAF is delivered as a service with a monthly fee, based on performance requirements for up to 10 sites. Additional subscriptions are available to limit the extra costs in case of volumetric DDoS attack (DDoS Fee Protection), to get assistance with Web security rule updates and tuning (Rule Update Service), or to reduce the scope of PCI compliance assessment with tokenization of client credit credentials (Edge Tokenization). of the products, and establish a positive identification with the product/brand and organization in the minds of buyers. This "mind share" can be driven by a combination of publicity, promotional initiatives, thought leadership, word of mouth and sales activities.Customer Experience: Relationships, products and services/programs that enable clients to be successful with the products evaluated. Specifically, this includes the ways customers receive technical support or account support. This can also include ancillary tools, customer support programs (and the quality thereof), availability of user groups, service-level agreements and so on.Operations: The ability of the organization to meet its goals and commitments. Factors include the quality of the organizational structure, including skills, experiences, programs, systems and other vehicles that enable the organization to operate effectively and efficiently on an ongoing basis.Completeness of VisionMarket Understanding: Ability of the vendor to understand buyers' wants and needs and to translate those into products and services. Vendors that show the highest degree of vision listen to and understand buyers' wants and needs, and can shape or enhance those with their added vision.Marketing Strategy: A clear, differentiated set of messages consistently communicated throughout the organization and externalized through the website, advertising, customer programs and positioning statements.Sales Strategy: The strategy for selling products that uses the appropriate network of direct and indirect sales, marketing, service, and communication affiliates that extend the scope and depth of market reach, skills, expertise, technologies, services and the customer base.Offering (Product) Strategy: The vendor's approach to product development and delivery that emphasizes differentiation, functionality, methodology and feature sets as they map to current and future requirements.Business Model: The soundness and logic of the vendor's underlying business proposition.Vertical/Industry Strategy: The vendor's strategyto direct resources, skills and offerings to meet the specific needs of individual market segments, including vertical markets.Innovation: Direct, related, complementary and synergistic layouts of resources, expertise or capital for investment, consolidation, defensive or pre-emptive purposes.Geographic Strategy: The vendor's strategy to direct resources, skills and offerings to meet the specific needs of geographies outside the "home" or native geography, either directly or through partners, channels and subsidiaries as appropriate for that geography and market.In the first quarter of 2014, Akamai completed the acquisition of DDoS protection service Prolexic Technologies. Gartner analysts expect future integration between Kona and the Prolexic offering.The Kona WAF is a good choice for existing Akamai customers as an extension to deployed Akamai solutions, and for large public websites looking for simple WAF deployment.StrengthsGartner clients cite the combination of DDoS protection and Web application security as adifferentiator when comparing Akamai with most competitors.Akamai leverages its visibility into a substantial share of Internet traffic to tune security signatures in order to avoid false alerts and improve detection, with multiple steps for anomaly detection that feed a scoring mechanism.Akamai's subscription model makes it easy for enterprises to purchase and enable Web application security. This is especially true for existing Akamai CDN clients, and for owners of very largehosted Web applications.The transparency and professionalism demonstrated in Akamai's reaction to the recent Heartbleed vulnerability inspires trust in its ability to handle security-related challenges.CautionsAkamai's WAF is available as a cloud service only. Akamai does not provide an on-premisesappliance option that many of its competitors offer to protect internal applications, or to maintain Secure Sockets Layer (SSL) secrets on the client's corporate network.Akamai lacks lower-price WAF subscriptions to reach smaller enterprises and midsizeorganizations.Kona Site Defender security still relies primarily on signatures and reputation scoring. It lagsbehind competitors in other capabilities, such as an automatic learning engine and the degree of custom configuration of Web application behavior.Akamai is growing the customer base for its WAF offering mainly from existing clients of other cloud services in the U.S., but Gartner does not see the vendor winning deals on Web application security needs.Return to TopBarracuda NetworksBarracuda Networks (CUDA), which is based in Campbell, California, provides a wide variety of information security and storage products that are largely targeted at small or midsize businesses (SMBs). Barracuda offers its Web Application Firewall line in a variety of form factors, including as a physical or virtual appliance, and also as a cloud-based service that can be deployed on the Microsoft Azure and Amazon Web Services (AWS) cloud platforms.SMB buyers and resource-strapped security teams that require a low-cost solution and attentive vendor support should consider this product.StrengthsBarracuda's WAF provides strong IP reputation, cookie protection and client fingerprintingcapabilities. It also combines embedded authentication features and integration with several third-party authentication solutions.Barracuda has a broad range of hardware appliances to support a wide variety of scalability and performance requirements, especially for SMBs; it is also one of the only vendors to offer a WAF on the Microsoft Azure platform.Barracuda customers rate its geographically distributed support capabilities quite highly.Barracuda offers a wide range of foreign language support in its management interface, including Mandarin, Cantonese and Korean.CautionsBarracuda's WAF lags behind its leading competitors in enterprise-level automation. It integrates with a low number of established vulnerability scanners for virtual patching, and the scanning results must be imported manually. Automatic learning capabilities are disabled by default.Customers note that the management graphical user interface (GUI) looks a bit dated, which can make it difficult to use in some situations.Barracuda heavily relies on a relatively small set of generic signatures to protect against XSS and SQL injection.Return to TopBeeWareFrance-based BeeWare has been marketing its technologies since 2003. Its products, which include WAF, Web services firewall and WAM, have been integrated into its i-Suite platform, which can be deployed as a physical or virtual appliance. The i-Suite solution also offers ADC features, such as load balancing, content caching, compression and traffic rewriting. BeeWare is one of the smaller vendors in the WAF space, and predominantly sells its WAF to the French market. In May 2014, it was acquired by DenyAll.Midsize and large French enterprises in financial, government and manufacturing sectors that have WAF and authentication needs should consider BeeWare on their shortlists, but also take into account the acquisition by DenyAll.StrengthsBeeWare offers an i-Suite version for the protection of applications hosted on AWS, MicrosoftAzure and other clouds (although deployment of this WAF cloud version is very low).Its i-Suite has strong protection for Web services and SSO features.BeeWare's WAF flow-based policy management interface may be attractive to customers that like an event-based graphical representation of a security policy.CautionsBeeWare's revenue and growth are low and lag behind most players in the WAF market.It has low visibility and does not appear on Gartner customer shortlists outside France.Its technology has limited anti-evasion techniques. It offers only generic SQL injection (SQLi) and XSS protection capabilities.Its non-Web Java client GUI, although graphical and rich, is not in-line with the general trend of Web-based GUIs.Its WAF has integration with only one DAST vendor, Qualys, and with only two SIEM vendors, Splunk and RSA, The Security Division of EMC.Return to TopCitrixU.S.-based Citrix (CTXS) is a global provider with a broad portfolio of virtualization, cloud infrastructure and ADC solutions. Citrix has offered WAF functionality (NetScaler AppFirewall) for more than a decade as a software option, or included in the "Premium" bundle of the NetScaler Application Delivery Controller suite. The Citrix hardware appliance product line (NetScaler MPX) can also run a license-restricted version of the full NetScaler software to act as a stand-alone WAF. In addition, Citrix provides virtual appliances (NetScaler VPX). The NetScaler SDX platform allows several instances of Citrix solutions, including ADC and NetScaler AppFirewall software in a single hardware appliance. NetScaler can also be bundled in Citrix Mobile Workspace offerings.Citrix NetScaler AppFirewall is a good choice for large enterprise clients that are looking for an easy way to add WAF functionalities to their existing Citrix infrastructures.StrengthsNetScaler AppFirewall includes mature features for Web security, and can be bundled with SSL VPNs for remote access of internal applications.Citrix NetScaler's ability to scale appeals to large organizations, especially when massive SSLoffloading is required.Citrix has a compelling ecosystem of partnerships with third-party solutions.Citrix offers an extensive range of hardware (MPX/SDX) and virtual (VPX) appliances.CautionsLike most ADC vendors, Citrix primarily targets enterprise clients with ADC solutions and does not focus its efforts on pure-play security use cases.Despite good visibility historically, Citrix recently has appeared less often on client shortlists than its direct competitors have.Citrix NetScaler's physical appliance price tag starts at $15,000 and lacks a price-competitive WAF offering for midsize organizations. Citrix's virtual appliance and NetScaler on AWS might offer less expensive alternatives.Citrix does not offer or collaborate with cloud-based DDoS protection services.Gartner does not see Citrix's WAF displacing the competition based on its security capabilities, but rather sees it as an accompanying sale for ADC placements.Return to TopDBAPPSecurityDBAPPSecurity, which is headquartered in Hangzhou, China, is a vendor of Web application and database security solutions. Its product offering includes a WAF (DAS-WAF) that was first released in 2007. DBAPPSecurity also provides a Web application vulnerability scanner (DAS-WebScan) and database audit platform (DAS-DBAuditor) that can collaborate with its WAF product.DBAPPSecurity is a good shortlist candidate in China for SMBs and large enterprises in financial and government sectors.StrengthsDBAPPSecurity has a firm base of faithful clients in China that praise the benefits of having aChinese provider. Those benefits include good resident support and local certifications.DAS-WAF includes automatic policy learning and Web application caching, and it can operate in transparent proxy or monitoring mode.Of all the vendors evaluated in this Magic Quadrant, DBAPPSecurity offers the lowest support cost relative to the WAF appliance price.CautionsDBAPPSecurity lags behind several competitors' WAFs in areas such as role-based management, detailed activity reports and authentication features.DBAPPSecurity has very limited market visibility and does not appear on Gartner customers' WAF shortlists outside of China.DBAPPSecurity's recent strategic focus moved toward its security scanners, and the DAS-WAF is not promoted on the international version of the vendor's corporate website.Return to TopDenyAllDenyAll is based in France and has marketed its WAF technology (rWeb) since 2001. Later, it added sProxy (a plug-in to rWeb with predefined policies for email, SharePoint and SAP) and rXML (a Web services firewall). DenyAll's rWeb WAF product was developed to secure HTTP(s), SOAP and XML traffic, and is currently available as a tool that is predominantly installed on enterprise's premises. Its technology can be deployed as software or appliance (physical or virtual). DenyAll is in the process of developing and testing its WAF cloud offering, and rWeb is already available via AWS and Microsoft Azure.DenyAll mostly focuses on the French market, and then on the European market, where it primarily targets midsize and large enterprises in financial and government sectors. It is a relatively small vendorin the WAF market, but is able to sustain a focus on technology innovation. In May 2014, DenyAll announced the acquisition of WAF vendor BeeWare.European organizations that are looking for high security first should consider adding DenyAll to their shortlists.StrengthsDenyAll's technology includes several advanced protection techniques, including JavaScript Object Notation (JSON) traffic analysis/protection, code leakage detection and a browser lightweightagent.It also offers a comprehensive list of anti-evasion techniques and a scoring list feature (a weighted scoring approach in addition to signatures) for protection against attacks, such as SQLi and XSS.The WAF technology combines security detection/protection features with caching, load balancing and high availability (with active-passive and active-active modes) features.DenyAll enables correlation between its WAF and DAST to increase the accuracy of detection and protection.The DenyAll rWeb offering is available via AWS to support Web protection for AWS-specificinfrastructure-as-a-service customer deployments.CautionsDenyAll mainly focuses on French and EU markets, which limit its visibility and adoption in other geographies.The acquisition of BeeWare will be a big challenge for DenyAll in the next 12 months. It coulddivert DenyAll from executing on its road map, but maintaining two product lines for too longwould annihilate much of the benefits from the increased R&D size.Its revenue and growth are low compared with the Leaders, Challengers and even some Niche Players in this Magic Quadrant.It has certified integration with only one SIEM vendor, Splunk, and does not have integration with reputation vendors' technologies.DenyAll's WAF correlation process between WAF and DAST mainly focuses on WAF integration with its own DAST, but not DAST from other application security testing vendors.Return to TopErgon InformatikErgon Informatik, which is headquartered in Zürich, has been shipping its WAF technology (Airlock) for more than 15 years. Ergon also develops other software solutions, including an authentication platform (Medusa) and mobile payment solutions. The Airlock WAF can be deployed as a reverse proxy, is available as a software and virtual appliance, and can run on Amazon Elastic Compute Cloud (EC2). Its pricing is primarily based on the number of protected Web applications and additional modules, such as SSL VPNs, XML security or graphical reports, which are available for an additional one-time fee. Airlock 5, which was released in January 2014, introduced a major operating system change and the full integration of an identity and access management (IAM) solution. Ergon will continue to support the previous versions of Airlock for 18 months.Ergon's Airlock is a good contender for European organizations' WAF projects, especially large banking and insurance enterprises from the DACH countries (Germany, Austria and Switzerland) and the Middle East region that have access management needs.StrengthsAirlock includes extensive techniques for Web application parameters, with URL encryption,various cookie protections (including a cookie store) and form parameter integrity checks.Airlock's integration of a full IAM solution adds comprehensive authentication and SSO features.Ergon gets good marks from users for its security expertise, the efficiency of its support, and its understanding of the needs and constraints of large financial institutions.CautionsAirlock does not offer centralized management, automatic Web application behavior learning or automated security signature updates, and it does not integrate with vulnerability scanners for virtual patching.Airlock lacks hardware appliance models. Instead, Ergon provides multiple ways to facilitate the installation of the software appliance.For SIEM integration, Airlock provides only a Splunk App, but Ergon reports that its customers have integrated with other SIEM technologies.Airlock has very low visibility in Gartner's customer base.Return to TopF5Seattle-headquartered F5 (FFIV) is an application infrastructure vendor that is focused on ADCs. The primary WAF offering is a software module for the F5 Big-IP ADC: the Application Security Manager (ASM). Other F5 security modules include the network firewall Advanced Firewall Manager (AFM) and the WAM Access Policy Manager (APM) module. ASM is also available on the virtual edition of Big-IP. The F5 hardware Big-IP appliance product line can also run a license-restricted (yet upgradable) version of the full software to act as a stand-alone security solution (such as a stand-alone WAF).F5 is a good shortlist candidate, especially for large organizations that own or are considering ADC technology.StrengthsAs a leading ADC vendor with a large installed base of clients, F5 leverages the scalability of its ADC Big-IP platforms and the strength of its ADC sales as the entry point for add-on WAF licenses.F5's WAF is an easy upgrade for existing F5 clients.F5's corporate teams and channels provide logistic capabilities and support that are larger and have more geographic coverage than many WAF vendors.。

Press the power switch to power up the loudspeaker. To create a working system, you will need• IP switch with a PoE+ (802.3at) output for the 4420A loudspeakeror an IP switch with no PoE support and a PoE+ power injector • CAT 5 or higher category Ethernet cable with RJ45 connectors • AES67, ST2110 or Dante audio-over-IP stream sourceEthernet port •PoE+ power input (IEEE 802.3at) •Management over Ethernet•Audio-over-IP stream inputPower on/offReset to factory settings push and hold for 10 secondsBalanced analogue line input•For 4420A setup and configuration, a computer running Macintosh OS X or Windows 10 operating system•Genelec Smart IP Manager software•Dante Controller softwareExample of powering the 4420A with a PoE+ enabled IP switch. With this method, the power budget available for all outputs connected to the IP switch must enable each 4420A to run at full PoE+ power. For 4 loudspeakers, the power supply must support 4 x PoE+ power level.Example of powering the 4420A with a PoE+ power injector. This method enables the use of standard non-PoE IP switches. Each power injector must support full PoE+ power level into the device.The 4420A supports automatic negotiation with the IP switch or IP power injector to set the PoE power level. However, in some cases it may be necessary to set the PoE power level in the switch manually.PoE IEEE 802.3af-2003 13 W PoE+IEEE 802.3at-200925.5 WThere are several Power-over-Ethernet standards. The 4420A loudspeaker supports the PoE+ standard but also works with the lower power PoE standard. When the 4420A also works with lower PoE power, the duration of high SPL output is shortened, and long continuous output signals play at smaller sound level than when the PoE+ power level is used. Genelec recommends using PoE+ power level with 4420A.5 SETTING UP AUDIO STREAMSAudio stream setup is done by using Dante Controller software. Download from https:///products/software/dante-controller4420A can receive up to two audio channels in a stream. Assign a channel in the Transmitters list for each 4420A input listed in the Receiver list.6 INSTALLING GENELEC SMART IP MANAGERAcoustic calibration, zone setup and loudspeaker management is done using Genelec Smart IP Manager software. Download Smart IP Manager athttps:///smart-ip-manager and follow screen instructions to install.7 USING SMART IP MANAGERLaunch Smart IP Manager. ClickSettings | Audio Network menu.Select a Network interfaceconnected to the same network with 4420A loudspeakers.Click Continue button.Smart IP Manager software scans the network every 5 seconds to find and show unallocated Genelec Smart IP products in the Default zone.Turn on audio inputs: mix à stream in àanalogue in à no input à mix.Unallocated Smart IP devices are listed under “Default” zone. Zone can be muted and level controlled with ‘–‘ and ‘+’ buttons.8 EDITING ACOUSTIC SETTINGSSelect a Smart IP loudspeaker. Click the ‘Acoustics’ tab on the right pane. To set several loudspeakers simultaneously, select all speakers (left side) and then adjust.APPLICATION PROGRAMMING INTERFACE (API)4420A Smart IP loudspeaker has a set of API commands that can be used to enable control of 4420A using a house automation system or similar IP network connected device. The document describing the API command and how to use them is available from Genelec. Please visit .MOUNTINGThe two primary mounting points are on the rear side. They have metric M6 x 10 mm holes (thread type is metric M6, thread depth is 10 mm). Use these for mounting brackets or the keyhole wall mount adapter.On the base of the loudspeaker carries a 3/8 in UNC-threaded hole compatible with a certain standard microphone stands. This can be used for additional support. The UNC thread is not compatible with metric threads.Pay attention to mounting screw lengths. Do not use long screws exceeding the depth of the hole as this can destroy the threads in the mounting points. Do not over-tighten. Do not use very short screws as the thread length is not enough to hold the weight of the speaker.See Genelec Accessories Catalogue on for a complete list ofmounting hardware options.Set ‘delay’ and ‘sensitivity’ as needed.Click on a filter button, select ‘filter type’ and adjust parameters. Select ‘preset’ toassign all parameters for selected speaker.MORE DETAILED INFORMATIONMore detailed information is available on the Genelec web site.Please visit the 4420A product page to download the 4420A Operating Manual with measurements and detailed loudspeaker performance specifications https:///4420aThe Smart IP Manager software product page at https:///smart-ip-manager enables you to download a detailed Operating Manual for the Smart IP Manager, with examples of how to use the software for different applications.SAFETY CONSIDERATIONSThe 4420A has been designed in accordance with international safety standards. The following warnings and cautions must be observed to ensure safe operating conditions:• Servicing and adjustment may only be performed by qualified service personnel.• The loudspeaker must not be opened.• Do not expose the loudspeaker to water or moisture.• Do not place objects filled with liquid, such as vases, on the loudspeaker or near it.• This loudspeaker can produce sound pressure levels in excess of 85 dB, which may cause permanent hearing damage.• Free flow of air behind the loudspeaker is necessary to maintain sufficient cooling. Do not obstruct airflow around the loudspeaker.• The loudspeaker is not disconnected from the power supply unless the CAT cable carrying the PoE power is removed from the loudspeaker. Powering down the speaker using the power switch does not disconnect power.• Ensure that mountings for example to walls or ceilings are able to carry the full weight of the loudspeaker in all circumstances, the installations have been designed and are implemented according to the local safety regulations and follow principles of good workmanship.• The Genelec products and accessories can come with instructions on the proper methods of installation and use. Follow these instructions.
