Hot Mic Output

The Hot Mic output is a balanced, line-level, transformer-isolated feed

of the signal from the currently selected microphone (panel or

headset). The Hot Mic output is active regardless of whether the panel

has talk paths set and regardless of the front-panel’s control settings.

Connect to pins 8 and 15 for a balanced output. Pin 7 is available as a

shield or ground source (see Figure 2-7).

Studio/Stage Announce Audio and Relay Outputs

The SA output is a balanced, line-level, transformer-isolated feed with

the same signal sent to the Hot Mic output, except it is only active

when the SA button on the panel’s front panel is pressed or when

activated by Logic Input #1 or #2, which is configured for the Studio

Announce Function.

Connect to pins 1 and 9 for a balanced SA audio output. Pin 2 is

available as a shield or ground source (see Figure 2-7).
