Using the Controls

Power

The power switch has two positions: off and auto. The auto

position is the default setting. This keeps the amplifier in a standby

mode. Using sophisticated signal sensing circuitry, the amplifier is instantaneously activated when a sig- nal is detected at either of the inputs. If no signal is detected after several minutes, the amplifier switches back to the standby mode. The off position overrides this circuit, turning the subwoofer off

Level

Since your subwoofer is designed to work in conjunction with other speakers, we have provided a level control will allow you to balance the output of your unit with the rest of your system. Once set, the level control should not require further adjustment. Begin with the level control at the minimum position. Slowly increase the level until the subwoofer's output is equal to that of your other speakers.

Note: Output level is relative and can be different from location to location. Always return to the normal listening location to evaluate any setting changes.

Connecting the SW 50

General Information

The diagrams on the following pages show three of the most common types of subwoofer connections. This information will guide you through the connection process.

First, a few words regarding the functioning of your powered subwoofer: All signals into your powered subwoofer will first pass through the crossover. The portion of the signal below the current crossover fre- quency setting will be reproduced by the subwoofer. The unprocessed signal will be passed to the hi level outputs. If you have a choice of connection options, remember that it may be easier to run long distances with speaker wire than with line connectors.

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

These RCA jacks are designed to accept a line level signal from a receiver, pre-amp, surround sound decoder 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. (Using the tape loop of a receiver or preamp is not recommended. Tape jacks typically send a constant level, regardless of the volume setting, unlike preamp outputs. This will affect the balance between the subwoofer and the rest of the system.)
