3.9 PDE 4537 Panel Audio/GPI Options Card
Figure 57 - PDE4537 Panel Audio/GPI Options Card
This card handles two balanced audio mix inputs and two balanced audio send outputs from the panel
it is fitted to.
One of the two outputs comes from the microphone output at line level and the other is a mix of MAIN
& AUX loudspeaker send signals pre thelevel controls.
The two line level inputs can be patched to either the mix with the microphone signal, mix with the AUX
loudspeaker signal ,or mix with the MAIN loudspeaker signal. Additionally there is a patch for routing a
second audio signal to be sent to the matrix when using the PDE4536 coax options card.
The factory default settings are for microphone input mix and auxiliary loudspeaker mix. In addition there
are four opto-isolated general purpose inputs and two DPDT relay outputs which can be programmed
with CMAPSi.
Contact Vitec Group Communications for suitable options.
