Logic Inputs #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
• Mic Off —momentarily turns off the panel’s microphone.
• Answer Back Talk/Clear—functions the same as the panel’s
“Answer Back” selector. 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.
• Speaker OFF—turns off the panel speaker, disabling all audible
output from the panel.
• PTT: Activate All Talk Keys—implements a push-to-talk function
for all talk selectors. When the logic input is active, the panel
operates normally. When the logic input is deactivated, all active
talk selectors are disabled. Any controls (relays, etc.) assigned to
the labels are activated or deactivated along with their assigned
labels. The LED indicators associated with the active talk
selectors operate normally regardless of the PTT status. This
input only controls latched talks.
• Activate Talk Switch #1— equivalent to pressing the panel’s first
(leftmost) talk selector; a momentary and latching activation.
• Activate Talk Switch #2—equivalent to pressing the panel’s
second talk selector; a momentary and latching activation.
• Activate Listen Labels Button—equivalent to pressing the “Listen
Labels” button to display listen labels on any display expansion
panel (XPL-12 or XPL-22) connected to the panel.
• PTT: Activate Two-Way Radio Keys—implements a push-to-talk
function for all two-way radio talk selectors. When the logic input
is active, the panel operates normally. When the logic input is
deactivated, all active two-way radio talk selectors are disabled.
Any controls (relays, etc.) assigned to the labels are activated or
deactivated along with their assigned labels. The LED indicators
