“LP” (Low-Pass): Configures the filter to
attenuate frequencies above the selected filter
frequency at a rate of 12dB per octave. This is
useful for connection of subwoofer(s) to the
XD200/2v2 in a bi-amplified system.
“HP” (High-Pass): Configures the filter to
attenuate frequencies below the selected filter
frequency at a rate of 12dB per octave. This is
useful for connection of component speakers
to the XD200/2v2 in a bi-amplified system.
2) “Filter Freq. (Hz)” The filter frequency
markings surrounding these rotary controls
(one in each Channel Section) 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 13).
Tuning Hint: If you are using the XD200/2v2
to drive a subwoofer system (“LP” mode), and
component satellite speaker systems (“HP”
mode), 80 Hz is a good baseline “Filter Freq.
(Hz)” setting. After properly adjusting the “Input
Sens.”, as outlined in Appendix A (page 12), you
can fine tune the “Filter Freq. (Hz)” control to
achieve the desired system frequency response.
REMOTE LEVEL CONTROL OPTIONAL
With the addition of the optional Remote Level
Control (HD-RLC), you can control the volume
of the XD200/2v2 from the front of the vehicle.
This is useful for subwoofer level control, rear
channel level control, center channel level 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 single-line, four-wire 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.
