Channel On Switch; Channel Off Switch; Mic Preamp Card - AudioArts Engineering Lightning Technical Manual

Channel ON Switch

The channel ON switch turns the channel signal ON and fires any channel ON
(START) logic mapped to the fader's source signal. The switch LED lights to indicate
the channel is ON and the ON AIR LED will light on the left upper corner of the
meterbridge if so programmed (see the discussion of OnAir Tallies in the "Console
Internal Programming" section).

Channel OFF Switch

The channel OFF switch turns the channel signal OFF. The switch LED lights to
indicate the channel is OFF.
A Mic Preamp Card*
A four channel microphone preamplifier card is fitted if needed for analog mono
mic level inputs that used to connect to microphones, which typically put out signals at
relatively low signal strength, and therefore require more amplification (increase
in signal strength) to be properly audible in the output. Mic level sources are
pluged into the four 3‑pin headers located on the Mic Preamp card. Recessed
front panel multi-turn trimpots, located underneath the hinged meterbridge, are
for adjusting the level of each microphone input independently.
Example: With a microphone input of –60dBm @150ohm at the port, gain trim can set levels from
‑22dBu to +16dBu (note maximum preamp gain is +76dB) at the PGM outputs.
The microphone preamplifiers are internally wired to the Input dipswitch that can
be programmed to feed the A source to the fader where you will control the microphone
levels (described below in the "Console Programming Options" section).
* One is standard, additional cards are available as options.
