The MRA units require adequate ventilation.

HAZARD OF OVERHEATING

 Do not cover or block the vents on the matrix switcher, MRA

amplifiers or power supplies.

 Provide a clear space around the equipment, at least 2 inches

(50 mm) to the front and rear and 0.6 inches (15 mm) above.

Failure to follow these instructions can result fire, overheating

equipment, or serious injury.

GENERAL USE GUIDELINES

General installing, cabling and programming tasks and are

described in the C-Bus™ Multi Room Audio Matrix Switcher

Installation instruction bulletin, other component instruction bulletins,

and in the software Help files.

Follow the guidelines below for general use of the Amplifier.

 Leave the equipment powered ON when not in use. The MRA

system uses very little power when not being actively used.

 The digital audio connections from the Matrix Switcher to the

Remote Amplifiers are for MRA system use only. They are not

compatible with A/V equipment from other manufacturers.

 Do not disturb the audio and control cables attached to the rear

panel of the Matrix Switcher. The C-Bus, digital audio and

Ethernet LAN cables look similar. Never plug them into the

wrong sockets. If you are not sure about cable connections,

refer to the Installation Instructions or call your system installer.
