The XM44 Electronic Crossover Network is a very flexible crossover design that provides individual outputs for 1, 2, 3 or 4 frequency bands on the 1- 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. Muting relays ensure there are no transients during turn-on or turn-off.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 1-way version, 2-way version, 3-way version and a 4-way version.
