Asymmetric or symmetric slopes (different slopes can be mixed)
Crossover frequency 20Hz - 20 KHz.
Subwoofer summing option.
Heavy duty gold plated RCA connectors for input and output.
No transients during turn-on or turn-off.
Options: Balanced outputs/inputs, baffle step compensation, notch/boost
filters, delay sections and bass boost filter (Linkwitz transform).
The XM44 Electronic Crossover Network is a very flexible crossover
design
that provides individual outputs for 2, 3 or 4 frequency bands on the
2-
3- and 4-way models respectively. The crossover frequency of XM44
Electronic
Crossover Network
can easily be set by replacing frequency modules.
Each frequency module has the capacitors and resistors that set the
crossover frequency and slope for
that channel. Normal slope is 24 dB/oct, 4th order, constant voltage,
but
modules for first, 2nd, 3th, 4th, 5th, 6th, 7th and 8th order slopes
are
also
available. When choosing slopes of 24 dB/octave and 48 dB/octave the
high-pass and low-pass outputs of the crossover are
always in phase with each other (Linkwitz-Riley alignment). Note that
the
slopes on the low, mid and high channels can be different, so
asymmetrical
slopes are possible. For example, a 2-way XM44 can easily be set with 6
dB/oct
on the high pass and 18 dB/oct on the low pass by choosing appropriate
frequency
modules.
One set of frequency modules is included whith the XM44 crossover.
Optional
plug-in modules are also available for special features like
delay, bass boost(Linkwitz transform),
baffle step compensation and notch filter.
The XM44 is available as a 2-way version, a 3-way version and a 4-way
version.
The XM44front panel has 2, 4 or 6 calibrated level controls (for left
and
right
) for each channel.
The level controls are 12 position stepped attenuators with 1 dB steps.
This
allows for very precise and repeatable setting of the output levels. A
sum
switch allows the low pass channels to be summed. This is useful when
using the XM44 with a common subwoofer.
Options for the XM44 include balanced inputs/outputs. Rackmount
brackets
are also available.
Also available an an option are 24 position stepped attenuators instead
of the standard 12 position attenuators for level control. These 24
position stepped attenuators are calibrated in 0.5 dB steps and allow
very accurate setting of the levels for each output.

Ideal for custom installing into other equipment, like amplifiers, etc. The XM44EMB has two channels on a single circuit board. Each channel takes one or two XM44 frequency modules. This allows each channel to be hi-pass, low-pass, bandpass, etc. Each channel has an input that can be configured as single ended or balanced. There is an output level control adjustment for each or the two channels. The board needs dual +/-15Volt supply. Supply voltage can be from +/-6V to +/-18V. The XM44EMB has an optional regulator section that allows the board to take power from a DC voltage supply of up to +/- 100V; this allows the crossover to take power from the powersupply of most power amplifiers.
