22、verall 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.Bass response should not overpower the room but rather be adjusted so there is a harmonious blend across the entiremusical range.Many users have a

23、tendency to set the subwoofer volumetoo loud,adhering to the belief that a subwoofer is there to produce lotsof bass.This is not entirely true.A subwoofer is there to enhance bass,extending the response of the entire system so the bass can be felt aswell as heard.However,overall balance must be main

25、ers,0,or oppositethe main speakers,180.Proper phase adjustment depends on several variables such as room size,subwoofer placement and listener position.Adjust the phase switch to maximize bass output at the listening position.Crossover AdjustmentThe Crossover Adjustment Control determines the highes

26、t frequency atwhich the subwoofer reproduces sounds.If your main speakers can comfort-ably reproduce some low-frequency sounds, set this control to a lowerfrequency setting, between 50Hz and 100Hz.This will concentrate thesubwoofers efforts on the ultradeep bass sounds required by todaysfilms and mu

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

32、, 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. Check DC resistance of woofer; it should be 3.4 ohms10%. 3. Connect a pair of speaker cables to driver terminals. Cable
