OPERATION
A.2.3
Audio Output Connectors
The processed outputs are impedance balanced, and wired; pin-1 directly bonded to ground as
required by the AES48 standard, pin-2 hot and pin-3 cold. An unbalanced input may be driven
by connecting pin 3 cold to the ground connection at the source end. When AES3 operation
is selected on an output pair, the Odd channel connector is used for both channels (e.g. Input
1 is used for channels 1 and 2).
A.2.4
Audio Input Connectors
All audio connections are fully balanced and wired; pin-1 ground as required by the AES48
standard, pin-2 hot & pin-3 cold. If an unbalanced source is used, a connection should be
made between the pin-3 cold signal and the ground connection at the source end. When AES3
operation is selected on an input pair, the Odd channel connector is used for both channels
(e.g. Input 1 is used for channels 1 and 2).
A.2.5
Power Inlet
The APG DMS48 unit should be connected to a suitable mains electricity supply using an
earthed IEC C14 connection power lead. The processor has a switch mode power supply
that is capable of operating with a nominal mains voltage of 85V to 240V, 50/60Hz without
re-configuration.
Note:
The DMS48 must be earthed to a suitable power earth; failure to do so may affect
performance and/or operation and will invalidate warranty and could be potentially hazardous.
A.2.6
Auxiliary Port
The auxiliary port is used for recalling the first two snapshots stored.

Operation
B.1
Starting up the unit
The unit will power up as soon as power is applied to the IEC power inlet; there is no power
switch. When power is present the unit will go through its start-up cycle - first all the indicators
will illuminate then go off, while the screen displays the boot loader information. Next the
screen will display the application firmware information, and all the mute buttons will illuminate.
The display will then show the default screen showing drive module configurations, the mutes
will then return to the state they were in when the unit was powered off.
