Xantech MRC88

Make/Model	Device Version	Connection Type
Xantech/MRC-88	N/A	Serial

Description:

This driver controls the Xantech MRC-88 multi-zone audio switcher/amplifier. This is an 8x8 matrix switch supporting analog audio and composite video. Six zones of audio amplification are provided on-board. The device supports IR routing and macros. The driver allows the device to be controlled directly from CQC, which may eliminate the need for Xantech keypads in some locations.

Quirks and Limitations:

The driver currently only supports installations of a single MRC-88. The “expanded” mode where the controller supports 16 zones and 8 sources is not supported, although implementing this in the future should be straightforward.

Driver Fields

This section lists the fields that the driver makes available. In some instances, a portion of the name has been omitted and replaced by an ‘X’ signifying either a zone or partition number. In these instances the driver creates one or more fields as required.
