NOTE:
Power is always supplied to the subwoofer electronics unless it is unplugged.
The auto-on circuitry only activates or deactivates the power amplifier. Make sure your
subwoofer and receiver are unplugged when making the connection.
Line level:
Use the
line level in
with most systems. These inputs accept the line level signal from
your receiver’s subwoofer output. The subwoofer’s circuitry filters out the high frequencies and
sends the remaining low frequencies to the subwoofer power amplifier.
Speaker level:
Use these high-level terminals with receivers that do not have subwoofer
output. The speaker inputs accept both left and right channel speaker signals from your receiver.
Connecting Your Subwoofer to Digital 5.1 Channel
Home Theater Systems
Digital 5.1 home theater electronics dedicate one channel (the “.1” of 5.1) to reproduce the
special low-frequency (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.
Use an RCA cable (not included), as shown, to connect your digital receiver’s subwoofer output
to the subwoofer. Use the
bypass crossover control
input. On the PV400, set the crossover to the
direct
position and connect to
line level in.
