OPT-100 Auxiliary Audio Option
The OPT-100 Auxiliary Audio option provides the following features:
• Hot Mic output
• SA audio and relay outputs
• Auxiliary audio line level output
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 panel
has talk paths set and regardless of the front-panel’s control settings.
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 panel’s front panel is pressed or when
activated by Logic Input #1 or #2, which is configured for the Studio
Announce Function.
Auxiliary Audio Line Level Output
The Auxiliary Audio Line Level output is a balanced, line-level,
transformer-isolated feed of the input to the panel’s internal speaker.
For example, this output could be used to feed an external amplifier
connected to loudspeakers.
EXPANSION PANEL OPERATION
Optional expansion panels provide additional selectors that operate
the same as a panel’s selectors, including talk, listen, tally, and error
indication.
The XPL-12 expansion panel provides 10 additional keys, while the
XPL-22 provides 20 additional keys. Each expansion panel offers
illuminated 5-character labels for every key.
Only one rack unit (1RU) of a standard Electronics Industry
Association equipment rack is required for each expansion panel. The
panels’ compact size makes them ideal for use in TV control rooms,
edit suites, mobile OB vans, and any other location where many
talk/listen keys are necessary but space it at a premium.
Although the center button (5) on the panel’s keypad is not marked for
a function, it has the function of displaying “listen” labels on any display
expansion panel (XPL-12 or XPL-22) connected to the panel.
Momentarily pressing and quickly releasing the “5” button will cause all
XPL panels to display the listen label assigned to the key. If the listen
and talk labels are the same, then there will be no change. The
function will time-out after 5 seconds.
