the panel. The program feed (program audio) can be heard on the
panel’s speaker and headset; it cannot be heard by other panels in the
Matrix system.
To connect an external program feed to the panel:
1. Connect the balanced audio pair to pins 1 and 9.
2. Connect a shield or ground connection if available to the connector’s
pin 2 (see Figure 2-6 on page 1-4).
Logic Input #1 and #2
Each input can control one of several functions, determined through
the configuration program. Typically, these inputs are connected to an
external foot switch, a panel-mounted switch, or the logic output of
another device.
The following functions are available:
• Mic On/Off—toggles the panel’s microphone on and off.
• Mute Mic Output To Frame—turns off the audio from the panel to the
frame. It does not turn off the Hot Mic output (described in
“OPT-100 Auxiliary Audio I/O Option” on page 8). For an example
of how to use this option, see “External Program Feed Input” on
page 4.
• Mic Off —momentarily turns off the panel’s microphone.
• Answer Back Talk/Clear—the same functions as the panel’s “Answer
Back” key. Holding down the switch activates a talk to a label in the
answer-back stack. To clear the label, quickly press and release
the switch.
• Studio Announce—sends the output of the panel’s selected
microphone (panel or headset) to the panel’s Studio Announce
(SA) audio output, and activates the SA relay. The microphone
output is not sent to the frame. The SA output and relay are only
present if the panel has the OPT-100 Auxiliary Audio I/O Option
installed. (The SA options are described in “OPT-100 Auxiliary
Audio I/O Option” on page 8).
• Speaker OFF—turns off the panel speaker, disabling all audible
output from the panel.
• PTT: Activate All Talk Keys (Push To Talk)—when enabled from the
configuration program and the logic input is active, the panel
behaves normally. When this function (logic level) is deactivated, it
disables activation of all talk labels, implementing a push-to-talk
function for the panel. Any controls (relays, etc.) assigned to the
labels are activated or deactivated along with their assigned labels.
The LED indicators associated with the active labels behave
normally regardless of this input’s activity. This input controls
momentary and latched talks.
• Activate Talk Switch #1—equivalent to pressing the panel’s first
(leftmost) talk selector; a momentary and latching activation.
