Multi Room Audio Matrix Switcher and System Installation Instructions

4 C-Bus Programming Requirements
After an MRA system has been installed, it must be configured using C-Bus Toolkit
software and the Multi Room Audio Rapid Programming Application (MARPA).
Toolkit software lets you do the following:
• Create a C-Bus project with a Group Address structure that is used by MRA
amplifiers and the MARPA software.
• Enable a C-Bus system clock and burden in the matrix switcher (if required).
• Configure each MRA amplifier so one or more C-Bus wall switches can control
it.

MARPA software lets you do the following:
• Assign an ID to the matrix switcher (in case multiple matrix switchers are used
on the same network of a C-Bus installation).
• Configure parameters for each audio source, for example:
o Define the label (description) displayed when the source is selected.
o Configure optional audio annunciation when the source is selected.
o Set the gain/attenuation for each source.
o Configure sources and radio station presets.
o Determine which C-Bus commands are triggered by the Dynamic
controls.
• Configure parameters for each zone, including,
o whether labels are sent to C-Bus DLT switches.
o whether the local input source is available.
o IR maps for dynamic control (if used).
MARPA also includes a bundled version of the C-Bus IP Utility for configuring the
network streaming feature in the deluxe matrix switcher.
