18、the outlets on the back of the receiver. Initially set the Subwoofer-Level Control to the “min”position. Turn on your sub by pressing the Power Switch on the rear panel.Turn on your entire audio system and start a CD or movie soundtrack at a moderate level. Auto On/Standby With the Power Switch in t

19、he ON position,the Status LED on the back panel will remain lit in red or green to indicate the On/Standby mode of the subwoofer. RED = STANDBY (No signal detected,Amp Off) GREEN = ON (Signal detected,Amp On) The subwoofer will automatically enter the Standby mode after approxi- mately 10 minutes wh

20、en no signal is detected from your system.The subwoofer will then power ON instantly when a signal is detected.During periods of normal use,the Power Switch can be left on.You may turn off the Power Switch for extended periods of nonoperation,e.g.,when you are away on vacation. Adjust Gain Turn your

21、 Subwoofer-Level Control up to the halfway position.If no sound emanates from the subwoofer,check the AC-line cord and input cables.Are the connectors on the cables making proper contact? Is the AC plug connected to a “live”receptacle? Has the Power Switch been pressed to the “On”position? Once you

22、have confirmed that the subwoofer is active,proceed by playing a CD,record or cassette. Use a selection that has ample bass information. Set the overall volume control of the preamplifier or stereo to a comfort- able level.Adjust the Subwoofer-Level Control until you obtain a pleasing blend of bass.

23、Bass response should not overpower the room but rather be adjusted so there is a harmonious blend across the entire musical range.Many users have a tendency to set the subwoofer volume too loud,adhering to the belief that a subwoofer is there to produce lots of bass.This is not entirely true.A subwo

24、ofer is there to enhance bass, extending the response of the entire system so the bass can be felt as well as heard.However,overall balance must be maintained or the music will not sound natural.An experienced listener will set the volume of the subwoofer so its impact on bass response is always the

25、re but is never obtrusive. Phase Control The Phase Switch determines whether the subwoofer speakers piston-like action moves in and out with the main speakers,0,or opposite the main speakers,180.Proper phase adjustment depends on several variables such as room size,subwoofer placement and listener p

26、osition. Adjust the phase switch to maximize bass output at the listening position. Crossover Adjustment The Crossover Adjustment Control determines the highest frequency at which the subwoofer reproduces sounds.If your main speakers can comfort- ably reproduce some low-frequency sounds, set this co

27、ntrol to a lower frequency setting, between 50Hz and 100Hz.This will concentrate the subwoofers efforts on the ultradeep bass sounds required by todays films and music.If you are using smaller bookshelf speakers that do not extend to the lower bass frequencies,set the Crossover Adjustment control to

28、 a higher setting,between 120Hz and 150Hz. NOTE: This control will have no effect if the LFE/Normal Selector is set to LFE.If you have a Doby Digital or DTS processor/receiver,the Low-Pass Frequency is set by the processor/receiver.Consult your owners manual to learn how to view or change this setti

From the signal generator, Connect both right and left line level inputs (RCA jacks) to signal generator and UUT. Use Y-cable if necessary from mono source. 2. On the amplifier, turn t

31、he LEVEL control full Counterclockwise (Min). 3. Turn on generator, adjust to 75mV, 50 Hz. 4. Plug in UUT; turn the power switch ON. Turn LEVEL control full Clockwise (Max). 5. LED (on amp panel) should now be Green; immediate bass response should be heard and felt from rear port tube opening. Sweep

32、 Function 1. Follow steps 1-5 above, using a sweep generator as a signal source. 2. Sweep generator from 20Hz to 1kHz. Listen to the cabinet and drivers for any rattles, clicks, buzzes or any other noises. If any unusual noises are heard, remove woofer and test. Driver Function (Woofer) 1. Remove wo

33、ofer from cabinet; detach + and - wire clips. 2. Check DC resistance of woofer; it should be 3.4 ohms10%. 3. Connect a pair of speaker cables to driver terminals. Cables should be connected to an integrated amplifier fed by a signal generator. Turn on generator and adjust so that speaker level outpu

34、t is 5.0V. 4. Sweep generator from 20Hz to 1kHz. Listen to driver for any rubbing, buzzing, or other unusual noises. 9 PS series PS210 subwoofer 10 PS series PS210 subwoofer PS210 Electrical Parts List Part number Qty DescriptionReference Designator PREMAP/MAIN/POWER PCB Capacitors 034-330525-300ZR1
