Crosspoint/ Output Driver Modules
The analog audio crosspoint module used is a 128x32 module. The switching integrated circuit
(IC) is a HCMOS 16x8 array. Thirty-two of these switching IC’s are arranged to form a 128x32
matrix.
Each output bus from the switching matrix feeds a differential output. The output driver provides a
symmetrical low impedance output signal.
The 64x64 frame has positions for two 128x32 / 32-channel output driver modules; the 128x128
frame has positions for four 128x32 / 32-channel output driver modules. Grounding the negative
side of the output drive adds +6dB of audio gain.
