Connections

After your speakers are properly placed, you are ready to wire your system.

NOTE: Power is always supplied to the subwoofer electronics unless it is unplugged or switched to the Mute position using the Audio On switch located on the rear panel. The auto-on circuitry only activates or deactivates the power amplifier. Make sure your subwoofer and receiver are unplugged when making the connection (All models include a main power switch which turns off all power to the subwoofer).

Power: When plugging your subwoofer in be sure to use a wall outlet, or dedicated electrical outlet. Some receivers will provide a switched outlet. Do not use this. These on-board electrical outlets do not offer the amount of current or proper isolation required by a power amplifier, such as the one in your subwoofer.

Line level or LFE: On most systems use the line level input or the LFE input. These inputs accept the line-level signal from your receiver’s subwoofer output. Your receiver’s manual should indicate which input is most appropriate.

Connecting the Subwoofer to Digital Home Theater Systems Using LFE

Digital 5.1, 6.1 and 7.1 home theater electronics dedicate one channel (the “.1”) to reproduce the special low-frequency effects (LFE) information (such as explosions and thunder) contained in digitally-encoded soundtracks.

Select ”subwoofer-yes” from your receiver’s set-up menu. Hooked up this way, the receiver’s amplifier is relieved of having

to reproduce the difficult low bass signals that can drive the receiver into audible distortion. In some cases it can also depend on several other settings within a receiver. We recommend consulting your receiver manual for further assistance in this area.

Use an RCA cable (not included), as shown, to connect your digital receiver’s LFE/subwoofer output to the subwoofer.

Connecting the Subwoofer to Stereo

For stereo use the “sub out” connection from your receiver to the input on the subwoofer marked “L” or “R”.
