Active Subwoofer

About Subwoofers

Subwoofers extend the bass response of your system beyond the limitation of

most speakers. They are used with, not in place of, your existing left and right

speakers. A subwoofer can dramatically enhance a stereo TV, a stereo system,

or a full fledged home theater.

Features

This active subwoofer features a highly efficient ported enclosure, a reinforced

driver and an amplifier with a passive low frequency crossover network. A line

level input is provided for fast and easy connection to virtually any system.

Using the Controls

Power

The subwoofer is off in the “OFF” position, on in the “ON” position and is activated

upon receiving a signal in the “AUTO” position.

Phase

The subwoofer has phase switch 0°and 180°

Gain

The control adjusts the volume of the subwoofer. Once set, the volume control should not require further

adjustment. Begin with the volume control at the minimum position. Slowly increase the volume until you can hear

the subwoofer. A subwoofer playing too loud can give your system a muddy sound, so be sure to balance the subwoofer

carefully with your other speakers.

Output volume is relative and can be different from location to location. Always return to the normal listening location

to evaluate any setting changes.

Crossover

The crossover frequency control determines the highest frequency at which the subwoofer reproduces sounds. It can be

adjusted from 50Hz to 150Hz for 8”,and25Hz to 150Hz for 10”&12”.

Placement Guidelines

Prior to installing your new subwoofer, please consider the following guidelines. Placing the subwoofer near a wall or in a

corner will greatly increase its bass response. As frequencies reproduced by subwoofers are long and need room to

propagate, a subwoofer placed near the listening position will not sound as full as one placed farther away. Please be

careful about placing anything directly on top of your subwoofer, as the vibrations of the speaker cabinet could cause these

items to fall.

Connecting the subwoofer

The following diagrams show four of the most common types of subwoofer connections.

Hi Level In

These inputs are designed to accept an amplified signal from the speaker outputs of a receiver, power amp or other device

not equipped with line level outputs.

Hi Level Out

The original amplified signal from your source is present at these outputs, for connection to the existing left and right

speakers.

Line In

The RCA-type jack of your Subwoofer is designed to accept a line level signal from a receiver, pre-amp, surround sound

decoder, television or similar device. When using a single line level output from another unit, a Y connector should be used

to send the signal to both the left and right inputs.

Hi Level Connections

Here the signal is already amplified as it leaves the

receiver/amplifier. The speaker terminals of this unit

are connected to the hi level inputs of the Subwoofer.

The left and right speakers receive the original amplified

signal from the Subwoofer hi level outputs.

Line Level Connections

In this example, the pre-amp outputs of a stereo

receiver are connected to the Subwoofer line inputs.

Television Enhancement

Many newer television sets are equipped with variable

Stereo outputs. The signal available at these outputs

varies with the television volume. In this situation,

these variable audio outputs can be connected directly

to the Subwoofer line inputs to enhance the bass response

of the television's built-in speakers.

Dedicated Subwoofer Connections

Many surround sound decoders, home theater

processors and audio/video receivers are equipped

with a dedicated subwoofer line output. In this case,

the signal is already processed and does not need to

return to the system or other speakers. Connect this

line output to the line inputs of the Subwoofer. A Y

connector should be used to feed this single output to

both the left and the right line inputs.
