The diagram above illustrates the basic setup of a multi-room audio system with selectable source inputs routed
through an audio matrix. See the notes below to understand the setup:
• This system utilizes a separate audio matrix switch between the sources and the amplifier to allow full control
of the source routing to each zone. Inline volume controls are utilized for zone volume adjustment so that
changing source volume won't affect more than one listening zone.
• Each of the zones powering Rooms 1 through 4 are using the NORMAL (4-8Ω) output mode to allow for a pair
of speakers to be attached for left- and right-channel audio in each zone. Individual zone volume is adjustable
through the inline volume controls in the rooms so that the volume level can be adjusted as needed.
• Zones 5 and 6 are both set to BRIDGED output mode so that more power can be delivered to a pair of large
outdoor speakers on the Back Patio. The matrix output has been connected to the left channel LINE IN of the
bridged amplifier zones so that stereo audio is played correctly from the pair of speakers.
• There is a control system installed on the job for source control that also has a 12 volt trigger output, so the
Power mode has been set to TRIGGER DC 12V. When any source is turned on for use, the control system
program also turns on the EA-AMP-12D-45A by energizing the trigger. When the system is turned off, the
trigger wire is de-energized and the amplifier returns to standby mode.
