Equalization Section
A four-band stereo EQ/filter section is included,
employing 3 sweep frequency peaking sections (each
±16dB with reciprocal curves) plus sweep frequency
(-12dB/octave slope) low pass (2.7KHz-26KHz)
and high pass (12Hz to 260Hz) filters. Note the
three-band EQ and HI/LO pass filter sections may be
switched in and out separately.
Peak LED
A peak reading LED indicator lights to indicate
overload conditions within the channel circuitry (the
indicator monitors both pre and post fader points in
the signal chain).
Cue and Solo
Both pre-fader CUE and post-fader/post-chan-
nel on SOLO functions are provided. These switches
tap the module’s PFL and AFL signals and route
them to the console’s stereo SOLO/CUE monitor
bus, where they may be used to feed operator head-
phones, control room monitors, dedicated speakers,
etc. (SOLO/CUE is mastered at the console’s con-
trol room monitor module; see Chapter 5.)
Direct Out
Each input module has an electronically bal-
anced direct output. It is post fader, post channel ON.
Preselector Panel
TV-80 input modules may be supplied with
optional overbridge preselector panels. These con-
sist of an eight-bank switch array that determines the
source signal being fed to the main module’s Line 1
input. As stated before, preselector panels do not
control audio directly; they send control pulses to
switcher cards mounted in a separate rackmount
Smart Select
® cage. The cage card then returns the
appropriate signal to the module. See pages 8-2 thru
8-5 for smart cage wiring details.
