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).
