Steep 24 dB/octave slope.
Crossover frequency 20 - 5000 Hz.
Outputs are always in phase.
Digital crossover frequency readout.
Fourth order constant voltage design (Linkwitz-Riley).
The XM6 electronic crossover network is a fourth order
constant voltage crossover design. The unit provides
both low-pass and high-pass outputs. The slope of both
outputs is 24 dB/octave. Because of the fourth order
design the high-pass and low-pass outputs of the
crossover arealways in phase with each other. The
crossover network is implemented as a fourth order
state variable filter. This filter provides both the
high-pass and low-pass function simultaneously,
guaranteeing a near perfect match of the high-pass and
low-pass responses. The crossover frequency of the
XM6 electronic crossover can easily be changed from
the front panel with a switch, from 20 Hz to 5000 Hz, in
steps ranging from 1 Hz at 20 Hz to 100 Hz at 5000Hz.
A total of 163 frequencies can be selected this way. The
actual crossover frequency is displayed on a 4-digit LED
display. A remote frequency control
switch can be connected to the main unit with a 15'
cable and allows changing the crossover frequency
setting from the listening position. Individual level
controls are provided for left and right channels high and
low pass outputs. A damping control, common to all
channels, allows adjustment of the frequency response
at the crossover frequency.
The electronic crossover
network can also be used to drive a subwoofer, where
the subwoofer is shared by the two channels of the
stereo system. In the summing mode the left and right
channel low pass signals are averaged and presented
at both left and right low pass output. The phase control
switch for each channel can be used to invert the signal
of each low pass output channel individually. This can
be used to compensate for an inverting power amplifier
or can also be used when a common subwoofer is
operated with two bridged amplifiers.
