Subwoofer Installation Manual

Inputs

These jacks accept a signal from an AV receiver, a surround-sound processor, a stereo receiver or a stereo preamp. In

a surround-sound system, use an RCA audio interconnect cable (not included) to connect the receiver or processor's

subwoofer output to the input jack labeled LFE. In a stereo system, connect two RCA cables (not included) from the

preamp or the receiver's preamp output to the jacks labeled R and L.

USB 5VDC output

This jack outputs 5-volt DC power, which can be used to power accessories such as a wireless subwoofer receiver/

transmitter system.

Power switch

This is the master power switch that turns on the AC power. It must be in the "on" position for the subwoofer to

function. If the power switch is on, the on/auto/off switch (see pg. 7 "off/Auto/On Switch") controls the subwoofer's

power.

AC cord input

This connector accepts a standard two-conductor AC power cord (included). Note that the jack is not polarized, which

means the connector can be reversed. Reversing the AC cord in this jack can sometimes fix hum (grounding) problems in

the audio system.

Subwoofer Placement

The more walls the subwoofer is near, the louder (and sometimes boomier) the bass will sound. If you want maximum

bass output, put the subwoofer in a corner. If this makes the bass too loud or boomy, move the subwoofer out of the

corner and closer to the center of the wall. Often, placing the subwoofer near or between the main speakers helps the

subwoofer blend better with the speakers, and gives the best compromise between maximum output and smoothest

sound. When you listen to evaluate different subwoofer positions, always do it from the chair or couch where most of the

listening will take place.

A simple trick used by many home theater enthusiasts is to place the subwoofer in the primary listening chair, play some

music with a melodic bass line (most pop and jazz recordings will work), and crawl around with your head about a foot or

two off the ground. Find the spot along the wall where the bass sounds the smoothest and most even from note to note,

and put the subwoofer there.
