“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.
