“x10” (High-Pass): Configures the filter
to attenuate frequencies below a frequency
TEN TIMES HIGHER than the indicated
filter frequency at a rate of 12dB per octave.
This is useful for connection of tweeters to
this channel pair in a tri-amplified system.
Channel 3 & 4 Filter: 12dB/octave High-Pass
or Bandpass Filter
“Off”: Defeats the filter completely, allowing
the full range of frequencies present at the inputs
to feed these channels. This is useful for systems
utilizing outboard active crossovers or requiring
full-range reproduction from this channel pair.
“BP” (High-Pass): Configures the filter to
attenuate frequencies below the indicated filter
frequency and above the Channel 1 & 2 Filter
Frequency, at a rate of 12dB per octave. This is
useful for connection of mid-bass or mid-range
speakers in a tri-amplified system.
“HP” (High-Pass): Configures the
filter to attenuate frequencies below the
indicated filter frequency at a rate of 12dB
per octave. This is useful for connection
of component speakers or coaxials to this
channel pair in a bi-amplified system.
Subwoofer Channel Filter: 12dB/octave
or 24dB / octave, Low-Pass only
“Off”: Defeats the filter completely, allowing
the full range of frequencies present at the inputs
to feed this channel. This is useful for systems
utilizing outboard active crossovers.
“12dB” (Low-Pass):
Configures the filter
to attenuate frequencies above the indicated
filter frequency, at a rate of 12dB per octave.
This is useful for connection of subwoofers in a
bi-amplified system. This shallower slope gently
attenuates high-frequencies from your subwoofer
signal and is often well-suited for sedans and
coupes with trunks.
“24dB” (Low-Pass): Configures the filter
to attenuate frequencies above the indicated
filter frequency, at a rate of 24dB per octave.
This is useful for connection of subwoofers in
a bi-amplified system. This sharper slope more
aggressively removes high-frequencies from your
subwoofer signal and is often well-suited for
SUV’s, wagons and hatchbacks.
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 17).
Tuning Hint: If you are using the XD700/5v2
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 16), 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 subwoofer channel (Subwoofer
Level) or of the entire XD700/5v2 from the front
of the vehicle (Master Volume).
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 of the selected
channels 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.
