AVN-MPPR Presenter Remote Unit 3
Front Panel Controls
Status and Mixer ID LEDs
On the left side of the panel, there are a number of status LEDs and above
the word “Mixer” there is also an indication of the virtual mixer being
controlled. When the unit has been grabbed by a mix engine and assigned
to a virtual mixer, the appropriate LED will be illuminated to indicate the
virtual mixer currently under control. If the unit is not currently assigned to
a virtual mixer, the Mixer ID LEDs will all flash red to indicate that this is the
case.
There are also a number of status LEDs which are used to provide a basic
overview of various system parameters. A software enabled limiter on the
Virtual Mixer output is configured to prevent audio over-hitting. When the
limiter is operational, the front panel Limit LED illuminates red. The front
panel also has LED indication to warn of power supply failure, network and
sync/clock failures.
Each of these LEDs can be illuminated in different combinations of colours
and flashing or non-flashing states. The table on the next page provides and
what each LED state signifies.
