AUXILIARY AUDIO LINE LEVEL OUTPUT
The auxiliary audio line level output is a balanced line-level
transformer-isolated feed of the same audio signal that is sent to the
panel’s internal speaker. For example, this output could be used to
feed an external amplifier connected to a set of ceiling loudspeakers.
Connect to pins 6 and 13 for a balanced output. Pin 14 is available as
a shield or ground source. Refer to Figure 4-25.
HOT MIC OUTPUT
The “hot mic” output is a balanced line-level transformer-isolated feed
of the signal from the currently selected microphone (either the panel
microphone or the headset microphone).
The hot mic output is active regardless of whether the panel has talk
paths set, and regardless of the settings of the front panel controls on
the panel.
Connect to pins 8 and 15 for a balanced output. Pin 7 is available as a
shield or ground source. Refer to Figure 4-25.
SA (STUDIO/STAGE ANNOUNCE) OUTPUT
The SA output is a balanced line-level transformer-isolated feed of the
same signal sent to the hot mic output, except that 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 configured for the studio announce
function.
Connect to pins 1 and 9 for a balanced output. Pin 2 is available as a
shield or ground source (refer to Figure 4-25).
SA RELAY
The SA relay is activated whenever the SA button on the front panel of
the panel is pressed or when activated by Logic Input #1 or #2
configured for the Studio Announce Function. Both “normally open”
and “normally closed” contacts are provided. They are rated at 1 A at
24 VDC. This relay is not designed for switching mains AC line voltage.
To switch an external device that runs on mains AC line voltage, use
an external relay (or other switching mechanism) that is activated by
this relay.
Refer to Figure 4-25. The following pins are available for the SA relay:
• N.O. (normally open)—Pin 3
• WIPER (common)—Pin 4
• N.C. (normally closed)—Pin 5
