On-Air Light (Tally Light)

The Tally Light output delivers 12 VDC / 150 mA when the Master Microphone Button is enabled.
It can connect up to two Solidyne LA100 signaling modules. Additionally, the console includes a built-in on-air light in the cabinet.
The Tally Light output automatically shuts off if the load exceeds 150 mA.

GPIO

The minijacks labeled GPIO are general purpose outputs (GPO, General Purpose Output), which allow controlling external devices when certain console channels are enabled.
  • On DX816: signals are generated by microphone channels MIC-1, MIC-2, MIC-3 and lines USB-1 and USB-2.
  • On DX822: in addition to the above, MIC-4, MIC-5 and MIC-6 also have GPO.
The control outputs are open collector type, functioning as a switch:
  • In inactive state → high impedance.
  • When a channel is enabled → output connects to ground.
Electrical specifications:
  • Maximum: +24 V - 0.1 A.
Connectors:
  • 3.5 mm TRS jack type, located on the rear panel.
  • On DX816: “MIC 1&2”, “MIC-3” and “LINE USB 6&7”.
  • On DX822: “MIC 4&5” and “MIC-6” are added.
