Multi Room Audio Matrix Switcher and System User's Guide
9
• The installer uses MARPA configuration software to set the volume of the
audio connected to the high priority input that is broadcast to all amplifiers.
• Any amplifiers in standby mode are switched on to ensure the audio is
broadcast as widely as possible. Five seconds after the broadcast audio
ceases, amplifiers return to standby (if applicable) and to the previously set
volume.
• A high priority (HI) broadcast uses left and right channel speakers. A low
priority (LO) broadcast uses right channel speakers only. Audio connected
to a high priority broadcast input must be of sufficient volume to trigger a
broadcast.
3 Rear Panel Features
The installer normally completes rear panel connections for you. If you need to
check a connection to the rear panel, use Figure 6 and Table 2 for reference.
Many network cables appear similar but have different electrical properties. You
can damage your equipment by plugging a cable into the wrong port. If you are
not absolutely sure about connecting cables, consult your system installer.
