Adjusting the Crossover Control
When using the Line Level inputs (not the LFE input) the subwoofer’s built-in crossover is engaged. As a starting point, set the
crossover control on the subwoofer about 10Hz higher than the lower limit of your main speakers’ bass response. Fine-tune
the crossover setting by ear for the smoothest blend with your main speakers. The best setting of the crossover control will
depend on speaker placement and personal preference.
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. When using a home theater receiver, set the speaker type to “Large.” The large
setting will produce a fuller sound.
Note
Certain receivers use speaker grounding circuits that may be incompatible with external powered audio products, such as
powered subwoofers. When speaker wire is used instead of line level cables, this incompatibility can result in an audible hum
when the receiver is turned off or switched to a different speaker channel.
If this should happen with your MSubwoofer,
you will need to make a ground cable and
connect it to either RCA line input on the
subwoofer and any unused RCA line input
or output
on your receiver (see diagram).
The proper
ground cable for this applica-
tion should consist of two male RCA plugs
that have
their negative outside terminals (or
“sleeve”)
connected to each other by any
length of single conductor copper cable.
Note: The inside positive (or "pin") terminals
should not be wired in either plug.
