Clear-Com i-Series Panels - Manual (Page 52)

When the external logic device is activated, it sends a control signal into your panel’s
microprocessor to perform one of several preset functions. such as turning the panel’s
microphone off or on, muting the microphone’s output, or turning the panel’s speaker off.
You choose the function to be performed from the Eclipse Configuration System under
“Advanced Settings” in the “Logic Inputs” menu. This allows the logic inputs to be
configured from a drop-down list of items described below.
Before wiring a logic device to the GPI connector, you must first select the logic device’s
function in the Eclipse Configuration System. For more information, refer to the Eclipse
Configuration System Manual.
The setting options are:
• Microphone On/Off
• Mute Mic Output to Matrix
• Microphone Off (Momentary)
• Answerback Talk/Clear
• Studio Announce
• Speaker Off
• PTT: Activate All Talk Keys
• Activate Talk Switch #1
• Activate Talk Switch #2
• Activate Listen Labels
• PTT: Activate Two-Way Radio Talk Keys
These settings are described in detail in the following sections.
Microphone On/Off (Toggle)
The Microphone On/Off function allows you to set up an external logic device, such as a
panel-mounted switch, a foot switch, or the logic output of some other device, to shut the
panel’s microphone on or off.
To use a logic device to turn the panel’s microphone off and on:
1) Select the Microphone On/Off option in the Eclipse Configuration System.
2) Connect a logic device (such as a foot switch, a panel-mounted switch, or the
logic output of another device) to the i-Series panel’s GPI connector.
3) Switch on the logic device to turn the panel’s microphone on. Switch off the logic
device to turn the panel’s microphone off.
Mute Microphone Output to Matrix
The Mute Mic Output to Matrix function allows you to set up an external logic device, such
as a panel-mounted switch, a foot switch, or the logic output of some other device, to shut
off the audio going from the panel to the matrix.
Note that this feature does not turn off the hot-microphone output described later in this
chapter. The A3M standard XLR connector labeled “J8” on the back of your i-Series panel
is the hot-microphone output connector. It provides a line-level output of the selected
