F Two Operating Manual操作手册F Two Active SubwooferGeneral descriptionThe G enelec F Two is a very compact active subwoofer designed to comple-ment up to five Genelec G One or G Two active loudspeakers as a .1 / LFE channel subwoofer in a 5.1 system or a pair of the slightly bigger G Threes. Linked together two F Two’s can also be used with G Fours. The F Two extends the system’s bass response down to 27 Hz and integrates perfectly with the main loudspeakers in any environment. The playback level for the whole system is conveniently controlled by the wireless volume control provided with the subwoofer. A wired volume control is available as an option.The F Two has integrated bass manage-ment for the two output channels which directs frequencies below 85 Hz to the subwoofer and higher frequencies through the output connectors to the main loud-speakers. When using the subwoofer for the .1/LFE channel of a multichannel system, we recommend that bass manage-ment is done in the processor or receiver and only the LFE channel is connected to the subwoofer.InstallationBefore connecting the audio signals, ensure that all equipment is switched off.As the F Two contains its own amplifier, no separate power amplifier is needed. Never connect the F Two to the loudspeaker out-puts of a power amplifier, integrated ampli-fier or receiver.Please follow the steps listed below for a succesful setting up of the subwoofer:1. Check the contents of the shipment.in addition to the subwoofer, there is awireless remote control, a mains cable,an IR extension cable and a Quick SetupGuide.2. Pull out the battery insulating strip fromthe underside of the remote control asshown in figure 1. This strip insulates thebattery from the contacts on the remotecontrol during shipping and the remotecontrol does not function before it isremoved.3. Place the subwoofer in its position.4. Connect audio cables from your signalsource(s). You can connect up to twodigital audio sources and two analogaudio sources.5. Connect the main loudspeakers tothe output connectors of the subwoofer.You can use either balanced XLR orunbalanced RCA connectors.6. Set the “LEVEL +10” and “-10 dB”switches on the subwoofer and mainloudspeakers according to Table 2 on thismanual.7. Adjust the phase of the subwoofer asinstructed in this manual and the QuickSetup Guide.8. Use test recordings and familiar musicpieces to judge the sound balance. Usethe “SUBWOOFER LEVEL” rotary controland the “BASS ROLL-OFF” dip switchesto fine-tune the balance. If this fails,consider relocating the subwoofer.Operating EnvironmentThe F Two subwoofer is designed forindoor use only. The ambient temperatureshould be 15-35 °C (50-95 °F) and the rela-tive humidity 20-80 %. Condensation is notallowed. If it has been stored or transportedin a cool environment, the product must beallowed to warm up in its packing to theambient temperature before connectingmains power.ConnectorsThe F Two is equipped with both analogand digital signal input connectors, thatcan be used simultaneously to connectup to four audio sources (two analog, twodigital). Switching between sources is donewith the Select button on the connectorpanel or with the “<” and “>” buttons onthe remote control. The colour of the LEDlight on the subwoofer enclosure indicateswhich source is selected.Analog Input ConnectorsThe F Two has two stereo inputs (3.5 mmjack and L/R RCA connectors) and an LFE/LINK RCA connector. The stereo inputsare parallel, so you can connect two audiosources at the same time, just play onlyone of them at a time. The Select functiondoes not work between these two inputs.The LFE/LINK input is used for the LFEFigure 1. Removing the battery insulating stripfrom the remote controlFigure 2. Connectors and controls of the F Two.(.1) signal in a 2.1 or 5.1 channel sound system or as the signal input in a multiple subwoofer system (see chapter Using Mul-tiple Subwoofers). The LFE/LINK input has a 120 Hz low pass filter, so it is not suitable for full frequency range signals.Digital Input ConnectorsThe F Two has two digital signal input con-nectors, one coaxial and one optical, thataccept stereo PCM format digital signal.You can connect two digital sources andswitch between them using the Selectfunction.Analog Output ConnectorsThe F Two has two pairs of analog stereoL/R output connectors, one with RCA con-nectors and the other with balanced XLRmale connectors. Connect signal cablesfrom these connectors to the main speak-ers. Both connector pairs carry the sameFigure 3. Audio cablingsignal so you can use main speakers with either RCA or XLR input connectors. These outputs are high pass filtered at 85 Hz (See chapter Bass Management). Additionally, the LINK RCA output provides a summed signal of both channels. Use this connector as a signal output to the next subwoofer when you want to connect several sub-woofers together. See chapter “Using Mul-tiple Subwoofers” for more information.System Volume Control ConnectorThis connector allows connecting the G enelec 9310A Wired Volume Control which is available as an accessory. When connected, the 9310A controls the volume of the whole system, including the main speakers.IR IN ConnectorIf the F Two is used with an infrared type remote control (see chapter Use with IR Remote Controls) and the desired location of the subwoofer does not allow an unob-structed line of sight to the receiver located next to the LED in one of subwoofer’s feet, the IR extension cable provided with the subwoofer can be connected here. The receiver end of the cable is then brought to a location where the IR remote control reception works conveniently, for instance close to the IR receiver of a television set when using the subwoofer and speakers with a TV .Subwoofer placement Bass Roll-OffNear a wall -2 dB In a corner-4 dBTable 1.

Suggested Level switch settings with different main loudspeakersFunctions And ControlsHT ModeTurn this switch to “ON” when you connect a sound source with its own volume control to the analog inputs of the F Two. In this mode the volume control of the F Two does not have effect on the analog signals. However, it works with the digital inputs, so you can use them to connect other signal sources.ISS Sensitivity LowIf the Intelligent Signal Sensing (ISS) func-tion switches the subwoofer on when there is no audio signal present, turning thisswitch to “ON” reduces the triggering sen-sitivity of the function.ISSThe Intelligent Signal Sensing (ISS) func-tion monitors the audio signal fed to the subwoofer. If there is no signal for approxi-mately 45 minutes, the function switches the subwoofer to Standby mode, reduc-ing the power consumption to less than 0.5 Watts. When the signal resumes, the subwoofer powers up again. There is a slight delay in the automatic powering up. In those environments where the subwoofer is required to be on all of the time, the ISSVOLUME UP VOLUME DOWN SELECT BUTTONSMUTEPOWERfunction can be disabled by setting the “ISS” switch to the “OFF” position. Then the subwoofer is continuously powered and can be turned off using the power button on the remote control or connector panel.LED OffThis switch deactivates the status indicator LED on the “foot” of the subwoofer.Roll-OffThese two switches attenuate the sub-woofer’s bass response. At 27 Hz the attenuation levels are -2, -4 and -6 dB (both switches “ON”).PhaseThese two switches provide phase adjust-ment for the subwoofer in -90 degree incre-ments. See chapter “Phase Alignment”.LinkThis switch selects the analog inputs and disables input channel selection. In addi-tion, it disables the remote control and sets the subwoofer’s level to maximum. Set this switch to “ON”, when using the subwoofer as a “slave” in a multiple subwoofer system. See chapter “Using Multiple Subwoofers”.LevelThese two switches allow adjusting the subwoofer’s level by -10 dB or +10 dB, providing level matching with different main speaker models. See Table 2 for some examples.Subwoofer LevelThis rotary adjustment adjusts the play-back level of the subwoofer. The level is increased by turning the adjustment clock-wise and reduced by turning it counter-clockwise.SelectThis button allows signal input selection between the two digital inputs and the analog input and initiation of the match-ing procedure for IR remote controls (see Matching IR Remote Controls).PowerThis button switches the subwoofer between Standby and Power mode. Note that this button does not completely dis-connect the subwoofer from the mains power. If this is necessary, the subwoofer’s mains cable must be disconnected. This button can also be used for restoring the factory settings by keeping it depressed for10 - 15 seconds. This returns the volumesetting on the remote control to factorylevel and deletes possible remote controlpairing and IR remote control matching.Also the source selection returns to auto-matic, which is the factory setting.Positioning In The RoomThe placement of the subwoofer in theroom affects the overall frequency responseand sound level of the system dramatically,as at low frequencies the effects of theroom are strong. Even a slight change inthe location of the subwoofer can cause amarked difference in the frequency balanceand often patient and methodical experi-mentation and testing is needed to find theoptimum placement.The placement will also affect the bassroll-off rate and the phase differencebetween the main loudspeakers and thesubwoofer. These effects can be compen-sated using the controls in the subwooferbut we recommend that at first you leavethe switches untouched and concentrateon finding the position where the subwoofergives the smoothest response, and only thenuse the controls to fine-tune the balance andphase alignment between the subwooferand the main loudspeakers.Start by placing the subwoofer close to thecenter of the front wall. We recommenda distance of less than 60 cm / 24” to thewall. This position gives increased acous-tic loading and sound pressure level due tothe proximity of the front wall and floor. Ide-ally the subwoofer and main loudspeakersshould be positioned symmetrically and atan equal distance from the listening position.If the frequency balance is not quite right,try moving the subwoofer to the left or rightalong the wall so that different room modesare excited at different levels. Positioningthe subwoofer close to a corner will boostthe bass level at lower frequencies and maycause asymmetrical spatial imaging.ISS TM AutostartThe automatic power saving function ISS(Intelligent Signal Sensing) can be activatedby setting the “ISS” switch on the connec-tor panel to “ON.” Automatic poweringdown to standby mode happens after acertain time when playback has ended. Thepower consumption in standby mode istypically less than 0.5 watts. Playback willautomatically resume once an input signalis detected from any source.Alternatively, the subwoofer can be acti-vated by pushing any button on the remotecontrol.There is a slight delay in the automaticpowering up. If this is undesirable, the ISS TMfunction can be disabled by setting the “ISS”switch on the connector panel to “OFF.” Inthis mode, the subwoofer is powered on andoff using the remote control or the powerbutton on the connector panel.The “ISS SENSITIVITY LOW” switchlowers the triggering sensitivity of theISS function. This can be necessary if thesubwoofer “wakes up” even if there is noaudio signal.Setting The Playback LevelThe “LEVEL +10 dB and LEVEL -10 dB”switches and the rotary “SUBWOOFERLEVEL” level adjustment can be used formatching the subwoofer’s playback levelwith the main loudspeakers (See Table 2).Fine tuning can be done with the rotaryadjustment knob.Setting The Bass Roll-OffSwitchesThe acoustic response of the subwoofermay have to be matched to the charac-teristics of the room and the positioning inwhich it will be used (see Table 1). To adjustthe subwoofer to match these character-istics use the ‘’BASS ROLL-OFF’ controlswitches located on the connector panel.When all Roll-Off switches are ‘OFF’, a flatanechoic response is obtained.Setting The Phase ControlThe effect of incorrect phase alignmentbetween the main loudspeakers andthe subwoofer is a drop in the frequencyresponse of the whole system at the mainloudspeaker / subwoofer crossover fre-quency. The phase difference between themain loudspeakers and subwoofer at thelistening position is dependent upon thedistance from the listener to the subwooferin relation to the main loudspeakers. Toavoid phase differences between theleft and right main loudspeakers andthe subwoofer, the subwoofer should beplaced close to the center of the front loud-speaker array.Two phase matching switches allow com-pensation for incorrect phase alignment.Four settings are provided between 0° and-270°.Coarse Phase CorrectionMethodConnect an audio frequency signal gen-erator to a signal input on the subwoofer which has a main loudspeaker connected to the corresponding “OUT” connector. If the loudspeakers are placed at differ-ent distances from the listening position, choose the loudspeaker that is nearer.Set the generator to 85 Hz. If a signal gen-erator is not available, it is possible to use an audio test recording which has a test frequency in the range 70 Hz to 100 Hz. Suitable test signals can be downloaded at and found in some smart phones.Toggle the -180° phaseswitch ‘ON’ and ‘OFF’ andset it to the position whichgives the lowest soundlevel at the listening posi-tion.Next toggle the -90°phaseswitch ‘ON’ and ‘OFF’,and again set it to theposition which gives thelowest sound level.Finally, set the -180°phaseswitch to the opposite set-ting.Matching IR RemoteControlsThe F Two subwoofer can be used with most IR remote controls, providing con-venient use with, for instance, the remote control of a TV set when connected to it via a fixed level digital signal input. Turn the subwoofer upside down so you can easily reach the “Select” button on the subwoof-er’s connector and the status indicator LED on the subwoofer’s foot is visible. The IR receiver is located in the LED. Note that the “Select” buttons on the RF remote control provided with the subwoofer do not actu-ate the matching.The matching procedure is as follows:• Keep the “Select” button on the subwoofer depressed until the status indicator LED starts blinking red.• Choose the button on the remotecontrol that you want to actuate “volumeup” function. Keep it depressed until theLED stops blinking. With some remotecontrols pressing the button multipletimes works better.• Now the LED blinks green, indicatingthat the button for “volume down” can beselected. Follow the procedure describedabove.• Next the LED blinks blue for selection ofthe button for “Select” button.• Yellow LED indicates the selection of“Mute” button.• Magenta LED indicates the selection of“Power” button.A short press on the “Select” button allowsyou to skip a step in the procedure, if youdo not want to “teach” all the commandslisted above. If you want to interrupt theprocedure, press “Select” for approxi-mately two seconds. This saves the set-tings made so far. If you don’t want tosave the settings, press the Power buttonfor two seconds. This will also delete thematching settings done by that point. If youwant to change the matched buttons, justredo the matching process.Matching The RF RemoteControl To The SubwooferThe remote controls delivered with F Twosubwoofers will function with any other F Twosubwoofer as well. If this is not desirable, forinstance when there are several F Two sub-woofers in the same premises, and the userwishes to avoid the situation that more thanone subwoofer reacts to the commandsgiven by each remote control, the remotecontrols can be matched to operate only onesubwoofer.1. Press and hold down the “Power” and“Select “ buttons on the subwoofer until theLED starts blinking white.2. While the LED is blinking, first pressand hold down the volume “+“ button onthe remote control and then the volume “-“button. Keep both buttons pressed for a fewseconds until the status indicator LED on thesubwoofer stops blinking. This indicates thatmatching is completed and the matchingoperation ends automatically.Now the subwoofer should only respondto commands given by the matched remotecontrol, and respectively, the matchedremote control should not work with otherF Two units. For cancelling the matchingoperation while the LED is blinking, pressand hold down the ”Power” button on thesubwoofer for two seconds. If you wish toundo a matching completely, press and holddown the ”Power” button on the subwooferfor ten seconds.NOTE: In some cases the local WiFinetwork can cause problems with the RFremote control, if they operate on the samewavelength. We recommend the use of an IRremote control in these cases.Using Multiple SubwoofersThe Genelec F Two subwoofer is equippedwith an LFE/LINK output connector to pro-vide an easy way of coupling two or moresubwoofers together in high SPL applica-tions, for instance when using the subwoof-ers with Genelec G Four active loudspeak-ers. Connected as described below, the“master” subwoofer controls the volumeof all subwoofers linked to it through thisconnector.Connect an RCA cable from the LINK con-nector of the “master” subwoofer to whichthe main loudspeakers are connected, to theLFE / LINK connector of the other, “slave”subwoofer and turn the LINK dip switch onthe “slave” subwoofer to “ON”.In the LINK mode, the subwoofer volumeis automatically set to maximum and the“slave” subwoofer only reacts to the poweron/off commands given with a remotecontrol. It follows the volume adjustmentand source channel selection done in the“master” subwoofer.When two subwoofers connected in thisway are positioned close to one another,bass level increases by 6 dB. Three sub-woofers give an SPL increase of 9.5 dB andfour subwoofers 12 dB compared to a singlesubwoofer.The rotary “SUBWOOFER LEVEL” adjust-ment knob should be set in the same posi-tion as that of the “master” subwoofer unlessthe subwoofers are placed in very differentpositions acoustically, for example one ina corner and one far from corners. In suchcase, it is advisable to measure the loudnessof each subwoofer separately and adjustthem individually for correct balance.Phase and Bass Roll-Off adjustments shouldbe done individually for each subwoofer in thechain, especially if they are not placed closetogether. To check the phase alignment forthe “master” subwoofer switch off the “slave”subwoofer and follow the instructions given inthe previous sections.To adjust the phase alignment of thePHASEPHASEPHASE“slave” subwoofer, you need to switch off the “master” subwoofer, connect a signal cable from one of the “slave” subwoofer’s output connectors to the corresponding loudspeaker and switch the LINK switch to “OFF”. This effectively changes the “slave” to “master” mode and the phase adjustment can be carried out. Return the connections and LINK setting on the “slave” subwoofer back to the “ON” setting after completing the adjustment.Safety ConsiderationsThe Genelec F Two complies with interna-tional safety standards. However, to ensure safe operation and maintain the equipment in safe operating condition the following warnings and cautions must be observed.• Do not use this product with an unearthed mains cable or a mains connection without the protective earth contact as this may lead to personal injury.• Danger of explosion if battery is incorrectly replaced.
