D) Subwoofer Level Control Only:
Req uired: a source unit or processor with
one pair of stereo outputs and dedicated
subwoofer outputs.
Inp ut Connections: the stereo pair of source
unit outputs each split with a “Y-Adaptor”
allowing the left signal to be sent to the “CH 1
(Left)” and “CH 3 (Left)” inputs and the right
signal to be sent to the “CH 2 (Right)” and
“CH 4 (Right)” inputs of the XD600/6. The
source unit’s dedicated subwoofer outputs are
connected to the “CH 5 (Left)” and
“CH 6 (Right)” inputs (select “6 Ch.” on the
“Input Mode” switch in the “Channel 5 & 6
Controls” section).
R e s u l t : in this mode, the user has the ability to
control the absolute level of the LF channels
relative to the HF channels.
E) Independent level control of all three
channel pairs:
R e q u i r e d : a source unit or processor with
two pairs of stereo outputs and dedicated
subwoofer outputs.
Inp ut Connections: one pair of stereo source
unit outputs is connected to the “CH 1 (Left)”
and “CH 2 (Right)” inputs, the second pair of
stereo source unit outputs is connected to the
“CH 3 (Left)” and “CH 4 (Right)” inputs and
the source unit’s dedicated subwoofer output
is connected to the “CH 5 (Left)” and “CH 6
(Right)” inputs (select “6 Ch.” on the “Input
Mode” switch.
R e s u l t : in this mode, the user has the ability to
control the absolute level of the LF channels as
well as both pairs of HF channels.
When using a source unit’s dedicated
subwoofer output, set the “Input Sens.” of any
channels receiving input from the subwoofer
output with the source unit’s subwoofer level
control set at 3/4 of full output. See Appendix A
(page 14) for details.
Crossover Setup for Bi-Amplified System
with one XD600/6:
Once the input sections have been configured
appropriately, go to the “Channel 5 & 6
Controls”. Select “LP” (low-pass) on the “Filter
Mode” switch and an appropriate “Filter Freq.”
(80 Hz is a good starting point).
Next, turn your attention to the “Channel 1 &
2 Controls” and “Channel 3 & 4 Controls” and
select “HP” (high-pass) on the “Filter Mode”
switches and an appropriate “Filter Freq.” (again,
80 Hz is a good starting point).
After proper adjustment of the “Input
Sens.” controls for all three channel pairs
using the method shown in Appendix A
(page 14), you can fine tune filter frequencies
and attenuate any pair of channels to achieve
proper balance. For precise filter frequency
information refer to Appendix B (page 15).
