Digital crossover frequency readout.
Fourth order constant voltage design (Linkwitz-Riley).
The XM66 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 are always 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 XM66 electronic crossover can
easily be changed from the front panel with a switch, from 20 Hz
to 4500 Hz, in steps ranging from 1 Hz at 20 Hz to 100 Hz at
4500Hz. The actual crossover frequency is displayed on a 4-digit
LED display. Individual level controls are provided for
left and right channels high and low pass outputs. A damping
control, common to left and right 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.This is useful where a single subwoofer is used. The phase control switch for each channel can be used to invert the signal of the low pass outputs. This can be used to compensate for an inverting power amplifier.
The XM66 is available with RCA connectors or with balanced XLR connectors. We can also make mixed version, like RCA inputs with XLR outputs. Please ask us about it. You can reach us at firstname.lastname@example.org.(585)423-0462.
