Example 3:
Preamp Line
Out/Low Level
In for
2 Subwoofers
Note that the
L/MONO input is
used on both sub-
woofers. Instead
of Y-adapters, you
may also use the
THRU outputs to
connect back to
the Main Inputs as
shown in Option
2 of Example 2.

Example 4:
Preamp Line
Out/Low Level
In using Hi-Pass
Out for
1 Subwoofer
The line level Hi-
Pass outputs send
audio signals
above
the Lo-Pass
filter setting to the
main L and R
power amplifier
inputs. This keeps
the low frequen-
cies out of the left
and right front
speakers, allowing
the subwoofers to
reproduce the
bass frequencies.
Note: These outputs are primarily intended for use in a two channel satellite/subwoofer system where the left
and right speakers are small and not designed to reproduce bass. It is also useful when your receiver/
amplifier/processor does not internally incorporate a low pass filter.
