SUBWOOFER CONNECTIONS

Option 1: Low Level Setup This is the recommended method for those amplifiers and receivers that are equipped

with a “Subwoofer Out” or “Pre-Amp Out” connection. Virtually all audio/video receivers have this connection clearly

marked on the rear panel. Run a dedicated interconnect cable with RCA connectors from the subwoofer output jack

to the line input on the subwoofer. In this setup, you will be using the internal crossover on your processor.

Option 2: High Level Input Setup If your amplifier or receiver does not have a dedicated subwoofer output, it will

be necessary to connect your new subwoofer directly to the speaker output terminals on the back of the unit. In this

scenario, you will be running high quality speaker wires from the left and right front outputs of your amplifier to the

high level inputs on the subwoofer. You will then need a second set of wires to carry the signal from the subwoofer

back to the main speakers.

AMPLIFIER SETUP AND BASS MANAGEMENT

Many home theater receivers/processors have a feature that controls how the bass is processed and delivered

to the subwoofer. It also adjusts the amount of bass that is sent to your satellite speakers. Look carefully in your

amplifier or receiver’s instruction manual for details on how to adjust for the speaker size (sometimes called “Speaker

Setup”) for your system.

When using a Dolby Digital or DTS-capable receiver/processor with the subwoofer connected to the subwoofer out

on your amplifier turn the “LOW-PASS FREQUENCY” control to the highest setting (200 Hz) on the back of your

subwoofer. Set the subwoofer crossover setting in the speaker setup section of the amplifier setup menu to 150 HZ

(or the next highest setting) and set the Satellites and Center channels to “small”.

If you are NOT using the receiver’s internal processor for subwoofer control then turn the “CROSSOVER FREQUENCY”

control on the subwoofer to the 3 o’clock (150 Hz) setting.

1. Power ON/Auto/OFF: This switch, when left

in the “Auto” position, automatically activates the

subwoofer when an audio signal is detected and

shuts the subwoofer off after approximately ten

(10) minutes of silence.

2. Subwoofer Level Control: Adjusts the volume

of bass energy allowing you to customize overall

tonal balance to your individual room acoustics

and personal taste.

Crossover

Frequency

Control:

This

adjustment varies the point at which the

subwoofer takes over the task of creating low

bass frequencies from the rest of the audio

signal permitting additional fine tuning of the total

system. A little experimentation with this control

will allow you to match the performance of the

subwoofer to the rest of your speakers resulting

in extraordinary, accurate, deep bass response.

This control should be turned to its highest

setting when the sub is connected through the

Subwoofer out on your receiver.

4. Phase Control: This adjustment matches the

phase - the in and out movement of speaker

cones - to that of your main speakers. Adjust this

control by listening to music with bass content.

The setting is correct when the bass sounds the

fullest.

5. High Level Input and Output: Used for direct

speaker connections from the left and right front

speaker outputs when a low-level subwoofer

output is not available.

6. Low Level Input: Used from pre-out or

Subwoofer-out.
