EXPANSION PANEL OPERATION
Optional expansion panels provide additional selectors that operate
the same way as a panel’s selectors, including talk, listen, tally, and
error indication. The XPL-12 expansion panel provides 12 additional
selectors. The XPL-22 expansion panel provides 22 additional
selectors. 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.
