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, line-level crossover or receiver with pre-amp level

outputs.TheSPEAKERLEVELjacksconnectdirectlytothespeakeroutputsofanyamplier,integratedamplier

orreceiver.Yourampliersectionwillnoticenoadditionalloadingeectswhenyouusetheseinputsduetotheir

very high impedance.

Important!!!

Do not use both LINE LEVEL and SPEAKER LEVEL connections simultaneously!

Volume Control

Thiscontrolallowsyoutobalancetheoutputfromthesubwoofertothemainspeakers/amplierinyoursystem.

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

listening to music. A good starting point for the volume control is 3 or 4 dots from minimum.

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 units with

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

with larger speakers which have greater low frequency output. With larger speakers, you might start with this

controlsetlower,suchas80Hz.

Abypassswitchisalsoprovidedifyouwishtouseanexternalcrossover.If you are not using an external

crossover, we recommend that you use the one provided within the unit for optimum performance!

Phase Adjustment - 0°/180°

Thiscontrolallowsyouto“reverse”thephaseofthesubwoofer’soutputsignal180°tocorrectforanypossible

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

listen to the system with music playing. Then move the switch from one position to the other and listen for a

change in low frequency output. The correct position will have a greater amount of apparent low frequency

output.

Crossover Switch - INTERNAL X-OVER/SUBWOOFER DIRECT

This switch allows the internal crossover circuitry to be removed from the signal path. This is required in certain

installationswhichroutethesignalthroughexternalprocessorswithacrossovercircuitoftheirown,suchasthe

new digital units. Simply move the switch to SUBWOOFER DIRECT todisengagethebuilt-incrossover.Forall

other installations which do not have a separate electronic crossover, we recommend you leave the switch set

to INTERNAL X-OVER to provide optimum performance.
