18、 Some receivers have one subwoofer output. In that case, it is recommended that you use a Y connector (not included) to maximize performance.BALBOA series SUB10 6Power OnPlug your subwoofers AC cord into a wall outlet. Do not use theoutlets on the back of the receiver.Initially set the Subwoofer-Lev

19、el 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 soundtrackat a moderate level.Auto On/StandbyWith the Power Switch in the ON position, the LED on the rearpanel will remain lit in red or green to

20、 indicate the On/Standby modeof the subwoofer.RED = STANDBY (no signal detected, amp off)GREEN = ON (signal detected, amp on)The subwoofer will automatically enter the Standby mode afterapproximately 10 minutes when no signal is detected from yoursystem. The subwoofer will then power ON instantly wh

21、en a signal is detected. During periods of normal use, the Power Switch can be left on. You may turn off the Power Switch for extendedperiods of nonoperation, e.g., when you are away on vacation.Adjust LevelTurn your Subwoofer-Level Control up to the “5” position(halfway). If no sound emanates from

22、the subwoofer, check the AC-line cord and input cables. Are the connectors on the cablesmaking proper contact? Is the AC plug connected to a “live”receptacle? Has the Power Switch been pressed to the “On”position? Once you have confirmed that the subwoofer is active,proceed by playing a CD, record o

23、r cassette. Use a selection that has ample bass information.Set the overall volume control of the preamplifier or stereo to acomfortable level. Adjust the Subwoofer-Level Control until you obtain a pleasing blend of bass. Bass response should notoverpower the room but rather be adjusted so there is

24、a harmoniousblend across the entire musical range. Many users have a tendencyto set the subwoofer volume too loud, adhering to the belief that asubwoofer is there to produce lots of bass. This is not entirely true. A subwoofer is there to enhance bass, extending the response of the entire system so

25、the bass can be felt as well as heard. However,overall balance must be maintained or the music will not soundnatural. An experienced listener will set the volume of the subwooferso its impact on bass response is always there but never obtrusive.Phase ControlThe Phase Switch determines whether the su

26、bwoofer speakerspiston-like action moves in and out with the main speakers (0), oropposite the main speakers (180).Proper phase adjustment dependson several variables such as room size, subwoofer placement andlistener position. Adjust the phase switch to maximize bass output at the listening positio

27、n. Crossover AdjustmentsThe Crossover Adjustment Control determines the highestfrequency at which the subwoofer reproduces sounds. If your mainspeakers can comfortably reproduce some low-frequency sounds,set this control to a lower frequency setting, between 50Hz and100Hz. This will concentrate the

28、subwoofers efforts on the ultradeepbass sounds required by todays films and music. If you are usingsmaller bookshelf speakers that do not extend to the lower bassfrequencies, set the Crossover Adjustment Control to a highersetting, between 120Hz and 150Hz.N NO OT TE E: This control will have no effe

From the signal generator,

31、Connect both right and left line level inputs (RCA) not the LFE jack - to signal generator and UUT. Use Y-cable if necessary from mono source. 2. On the amplifier, turn the LEVEL control full Counterclockwise (Min). 3. Turn on generator, adjust to 100mV, 50 Hz. 4. Plug in UUT; turn the power switch

32、ON. Turn LEVEL control full Clockwise (Max). 5. LED should now be Green; immediate bass response should be heard and felt from rear port tube opening. 6. Turn off generator, turn LEVEL control fully Counterclockwise (Min), disconnect RCA cable. Sweep Function 1. Follow steps 1-6 above, using a sweep

33、 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 woofer from cabinet; detach + and - wire clips. 2. C

34、heck DC resistance of woofer; it should be 3.3 ohms 10%. 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 output is 5.0V. 4. Sweep generator from 20Hz to 1kHz.

35、Listen to driver for any rubbing, buzzing, or other unusual noises.
