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 edged home theater.
Features
This active subwoofer features a highly ecient ported enclosure, a reinforced
driver and an amplier 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 o in the“OFF”position, on in the “ON”position and is activat-
ed 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 dierent 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 40Hz to 150Hz.
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 vibra-
tions 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 amplied signal from the speaker outputs of a receiver, power amp or
other device not equipped with line level outputs.
Hi Level Out
The original amplied signal from your source is present at these outputs, for connection to the existing left and
right speakers.
