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
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.
