utilizing outboard active crossovers or requiring
full-range reproduction from one or more of the
XD800/8v2's channel pairs.
"LP" (Low-Pass):
Configures the filter to
attenuate frequencies above the selected filter
frequency at a rate of 12 dB per octave. This is
useful for connection of subwoofer(s) to one
or more of the XD800/8v2's channel pairs in a
hi-amplified system.
"HP" (High-Pass):
Configures the filter to
attenuate frequencies below the selected filter
frequency at a rate of 12 dB per octave. This is
useful for connection of component speakers to
one or more of the XD800/8v2's channel pairs in
a hi-amplified system.
2) "Filter Freq. (Hz)"
The filter frequency
markings surrounding this rotary control
are for reference purposes and are generally
accurate to within 1/3 octave or better. If you
would like to select the filter cutoff frequency
with a higher level of precision, consult the
chart in Appendix B (page 15).
Tuning Hint:
If you are using the XD800/8v2
to drive a subwoofer system
("LP" mode),
a
component satellite speaker system
("HP" mode)
or both, 80 Hz is a good baseline
"Filter Freq.
(Hz)"
setting. After properly adjusting the
"Input
Sens.",
as outlined in Appendix A (page 14), you
can fine tune the
"Filter Freq. (Hz)"
control to
achieve the desired system frequency response.

With the addition of the optional Remote
Level Control (HD-RLC), you can control the
volume of two, four or all eight channels of the
XD800/8v2 from the front of the vehicle. This
feature can be used for subwoofer level control,
rear channel level control, zone control, or even
as a master volume control for the system.
The HD-RLC connects to the jack labeled
"Remote Level Control" on the Connection Panel
of the amplifier using a standard telephone cable
(supplied with the HD-RLC). If desired, multiple
XD (and HD) amplifiers can be controlled from a
single HD-RLC controller using a simple,
non-duplex phone line "splitter" and multiple
phone cables.
When connected to the amplifier, the
HD-RLC operates as follows. At full counter-
clockwise rotation, the audio will mute
completely. At full clockwise rotation the level
will be the same as if the HD-RLC was not
connected at all. In other words, it operates
strictly as a level
attenuator.

"Remote Level Mode" Switch:
This switch
allows you to assign the operation of the
HD-RLC to one, two or all four pairs of channels.
In the
"All"
position, the HD-RLC knob will
affect all four channel pairs equally.
In the
"5-8"
(middle) position, only the level
of channels 5, 6, 7 and 8 will be affected by the
HD-RLC knob (channels 1, 2, 3 and 4 will not).
In the "7
& 8"
position, only the level of
channels
7
and 8 will be affected by the HD-RLC
knob (channels 1 through 6 will not).
