Crossover Setup
for
Bi-Amplified
System with
one
M4300
and
a separate subwoofer amplifier:
Once the input and preamp
output
sections
have been configured appropriately, go to the
"Channell
& 2
Controls"
and
"Channel
3 &
4
Controls"
You
will set
both
control sections
identically to start:
Select
"HP"
(high-pass) on the "Filter Mode"
switch
and
an appropriate "Filter Freq." (80 Hz
is
a good starting point). Make these adjustments to
both control sections.
After proper adjustment
of
the M4300's
"Input
Sens." controls,
and
the subwoofer
amplifier's input sensitivity controls, you can fine
tune filter frequencies and attenuate either pair
ofchannels to achieve proper balance. For proper
adjustment
of
the
"Input
Sens." controls
of
the
M4300 use the method shown in Appendix A
(page
14).
For precise filter frequency information
for the M4300 refer to Appendix B (page
15).
Refer to the subwoofer owner's manual for
proper adjustments.
