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 station 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 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 station’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 7).
