REMOTE INTERFACE CONNECTOR
ON Logic
The ON logic outputs are an open collector transistor that is switched on when the channel on switches are pressed.
The open collector outputs can be connected together to switch something collectively, such as an ON AIR light for
example. Max current per channel is 50mA.
Mute inputs
The mute input channels can be switched on with a button pulling them to ground or an open collector transistor switch
to ground. When activated the relevant channel is muted and the ON light extinguished.
Start/Cue logic
The Start/Cue logic from the Stereo channel ON switches is designed to interface to a common standard employed by
Denon and Pioneer equipment. The logic signals are usually wired to a 2 pole 3.5mm jack plug where a low pulse on the
tip starts the deck and a low pulse on the sleeve stops or cues the deck. There needs to be some form of ground con-
nection between the equipment for this to work—normally effected by the audio connector leads.
External meter outputs and comms mic feed
These feeds produce PGM L & R signals for external metering equipment. These are line level analogue signals, the level
at 0VU will be 0dBu. There is also a comms mic feed that can be used to communicate with an engineer or similar.
External power
There is a 10v supply available for relays, ON air lights etc. Max current draw 100mA. A +15v/-15v supply is also availa-
ble to supply low current audio equipment such as a powered PPM meter. Max current draw 50mA.
