Each amplifier is shipped (unless otherwise specified) with the following factory settings:Front panel: Rear panel: On/Off Switch = Off Attenuators = ∞High Pass Filter(s) = OffGain Selector = Max Gain Position Mode Selector = Stereo Limiter Switch = OffBefore connecting to mains power, make sure that the switches are set to the configuration needed for your particular application. Always switch the amplifier off before making any changes to the settings. Failure to do so could result in damage to the unit or other components in your system. CAUTION: When mounting or connecting the amplifier, always disconnect it from the mains. Use four screws and washers when mounting the amplifier to the front rack rails. Rear support is also recommended, especially for mobile or touring use. To reduce the risk of fire or electric shock, do not expose this apparatus to rain or moisture.RequirementsKLR-Series amplifiers have specific physical, electrical and signal requirements for proper operation. These requirements will vary depending on your specific application, setup, and the settings on the amplifier. When setting up and testing your system, please take special care to double check all connections and settings. Please refer to the specifications section of this manual for specific input, output and other figures.Installation DensityKLR-Series amplifiers produce substantial power output from a small chassis. Whendriven at the higher-end of their potential, they do produce heat that must be dissipated. In cases where multiple KLR amplifiers are mounted together (or a single KLR with other equipment), it is recommended that a 1RU space is left between units to allow for proper air circulation. If the amplifier overheats, it will go into ‘thermal’ protect mode to prevent damage to itself and any connected components and speakers.Important Safety Instructions – 2 Introduction - 3 The KLR Series - 4 Physical Description - 5 Front Panel Rear Panel Installation – 6 Requirements Installation Density Typical Applications Connectors & Polarity Speaker Connections Troubleshooting - 10 Spec Table - 11 Warranty - 12Operator Manual – KLR Series AmplifiersPage - 7All Rights Reservedr 0611Typical Applications (Note: KLR 5000 not shown – see page 5)The most common use of a KLR-Series amplifier is a 2-channel source driving 2 speaker channels. In this illustration, the amplifier is receiving a stereo signal and is driving two stereo speakers. The amplifier is in STEREO mode.Another use of a KLR-Series amplifier is a single channel source driving both speaker channels. In this illustration, the amplifier is receiving a signal and is driving both channel speakers with the same signal. The amplifier is in PARALLEL mode.KLR-Series amplifiers are well suited to BRIDGED operation to drive a speaker load such as a subwoofer. This illustration shows a KLR driving a signal in BRIDGED mode. Note the special wiring to the channel 1 connector for Bridge mode. Minimum Bridged load impedance is 4Ω (2Ω per channel).Important Safety Instructions – 2 Introduction - 3 The KLR Series - 4 Physical Description - 5 Installation – 6 Requirements Installation Density Typical Applications Connectors & Polarity Speaker ConnectionsTroubleshooting - 10 Spec Table - 11 Warranty - 12Page - 8Operator Manual – KLR Series AmplifiersCopyright© 2011 – Ashly Audio Inc.Connectors & PolarityKLR-Series amplifiers utilize three types of professional audio connectors.

Pressurize thegauge to 100% of the range (which isequal to the displayed value) utilizing apressure standard with accuracy fourtimes greater than the unit being cali-brated.2Press ENTER. Full-scale calibra-tion is now complete.Notes:1. I f the digital gauge under test is not pressurized while in span adjustment of full-scale range,an ERROR message will be displayed when the ENTER button is pressed. If this occurs, press the ZERO CLEAR button on the keypad to return to the previous screen.2. A SME B40.7-1998, section 6.1.1.1 recommends the working standard for the gauge being tested is 4X better than the digital gauge under test. This means the pressure standard measuring the full-scale pressure being applied to the gauge should have an accuracy four times greater than the unit being spanned.Zero SP (span):This feature allows setting the % of span in which the zero button will operate. Span is limited to pre-vent accidental tare of process pressures. Options are 5%, 10% or DISAB (5% is the factory default and means the unit can be r ezeroed between ±5% of span). If DISAB is selected, the zero button is deactivated and no display change will occur when the zero button is pushed.Step 1:P ress the CONFIG key until the word ZERO SP appears.Step 2: Press ENTER.Step 3:E nter user five digit password (PW). This is the same password established to accessthe CONFIG mode in the menu.Step 4:P ress the CONFIG key to select thedesired option.Step 5:P ress ENTER to finalize the selection. Notes:Selecting the DISAB feature does not disable the CLEAR button on the keypad for the MAX/MIN fea-ture. If the DISAB feature is selected, pressing the ZERO button on the keypad will cause the display to read DISAB for two seconds. The gauge will then revert back to the unit of measure of the gauge. The DISAB feature disables the zero feature of the gauge. Zero Disable Feature:This feature allows disabling the Zero/Clear button on the keypad. It also allows for a zero tolerance of either 5% (default) or 10% of the gauge range. Step 1:P ress the CONFIG key until the word ZERO SP appears.Step 2:Press ENTER.Step 3:A prompt appears to enter PW (enterpassword).
