The talkback system can be inhibited when the console is in on-air mode. By default, when in on-air mode, talkback
cannot be routed to a main. See

Reverse Talkback

Reverse talkback is a process which allows a performer/presenter to push a button to automatically route their
microphone signal to Summa's PFL loudspeaker output. Summa has three reverse talkback inputs.
Microphones should be patched to reverse talkback inputs using the method described about for patching to talkback
inputs. Reverse talkback inputs are also available as destinations for GPIO patching. A switch should be patched to the
reverse talkback GPI so that when the performer/presenter wishes to be heard they simply push the switch to route their
microphone to the PFL loudspeaker in the control room.
To patch a switch to a reverse talkback GPI:
1. Launch the PC Application on the 1U support PC.
2. Select GPI from the menu buttons down the left hand side of the screen.
3. Select FILTER INPUTS in the General Purpose Inputs window and select the I/O box to which your GPI switch is
connected.
4. Select FILTER INPUTS in the GPI functions window and select 'reverse talkback' from the list.
5. Select the port to which your switch is connected.
6. Select the reverse talkback input you wish to use.
7. Select PATCH.
