INSTALLATION

Inputs

Your new subwoofer is equipped with speaker-level and line-level inputs. Use the LINE LEVEL jacks when

connectingyoursubwoofertoapre-amp,signalprocessor(suchasLFEout),linelevelcrossover,orreceiver

with pre-amp level outputs. When using the line level jacks, some receivers may not provide enough signal to

havetheunit’sauto-onfeatureoperateproperly.Additionally,thislackofsignalmayalsocausethesubwoofer

to produce less output than it is capable of.

To alleviate this condition, we recommend the following steps:

1) Ifusinglineleveljacks,BOTHTHELEFTANDRIGHTINPUTSHOULDALWAYSBEUSEDneveruse

just the left or just the right input. If using line level connections from a preamp or signal processor, use

both Left and Right inputs from your preprocessor or preamp and connect them to the Left and Right

inputsonyoursubwoofer.(Seegure4onpage10.)

2) IfusingareceiverwithLFEout,besuretheLFEchannelissendingadequatesignaltothesubwoofer.

Thesubwoofer’sdefaultvolumesettingis30ona1-80scale(roughly1/3volume).AdjusttheLFE

channel on your receiver or processor to achieve the desired bass output. See your receiver or

processor’sowner’smanualformoreinformation.(Seegure5onpage11.)

Volume Control

This control allows you to balance the output from the subwoofer to the main speakers in your system. This

control should be set to achieve similar output levels from both the main speakers and subwoofer when listening

to music. The default volume setting is 30 on a 1-80 scale.

Warning:

Some manufacturers preset their receivers with the Sub-Out channel signal at a minimum level. It is very important

to verify that your receiver Sub-Out channel is set to the same output level as your front right and left channels.

Refer to your receiver manual for the individual channel level adjustment procedure. If your receiver Sub-Out

channel is set too low, the subwoofer may appear to have a weak output, it may sound noisy or distorted, and

the Auto On/Off feature may not operate properly.

Low-pass Crossover - 40 to 120 Hz

All inputs sum the left and right channels together, with the resulting signal passing through an adjustable

low-passcrossoverbeforebeingamplied.Thecrossovercontrolallowsyoutoadjusttheupperlimitofthe

subwoofer’sfrequencyresponsefrom40to120Hz.Thesubwoofer’sresponsewillbeginrollingoabovethe

frequency you set this control to. You should set the crossover frequency to obtain a smooth and seamless

transition from the subwoofer to the main speakers in your system. If your main speakers are smaller with limited

lowfrequencyoutput,youmaywishtochooseahigherfrequency(suchas100-120Hz)thanyouwouldwith

speakers,youmaywanttosetthisevenlower,forexample70Hz.

Phase Adjustment - 0°/90°/180°/270°

This control allows you to change the phase of the subwoofer’s output signal to correct for any possible mismatch

andresultingcancellationbetweenthesubwooferandyourmainspeakers/amplier.Toadjust,simplylistento
