Submaster Module
General
TV-80 audio consoles come equipped with four SUBMASTER
modules. Each submaster module controls two mono subgroups
and houses the master circuitry for two console AUX SEND and
two console MIX MINUS outputs. There is an associated dual
fader panel directly beneath each main module faceplate.
Submaster audio I/O (input/output) connections are made via
two DB-25 multi-pin connectors (“A” upper; “B” lower) located
on the back rear panel of the module (see page 3-6).
Please refer to the signal flow diagram on page 46 of the
Technical Drawings in conjunction with the text of this chapter.
Main Module Controls
Aux Master Section
The TV-80 console has eight AUX send outputs; each of the
console’s four submaster modules contains the master controls
for two console AUX sends. Each control set consists of a master
level pot, an ON switch, and a SOLO switch, which allows the
console operator to spot monitor that particular AUX signal via
the console’s SOLO interrupt circuit and SOLO/CUE VU meters.
Note AUX insert points are provided (they may be PCB-jumper
bypassed—the factory default; see page 3-4).
Mix Minus Master Section
The TV-80 console has eight MIX MINUS outputs; each of
the console’s four submaster modules contains the master con-
trols for two console MIX MINUS outputs. Each control set
consists of a master level pot, an ON switch, and a SOLO switch,
which allows the console operator to spot monitor that particular
MIX MINUS signal via the console’s SOLO interrupt circuit and
SOLO/CUE VU meters.
Mix Minus Confidence Feed
This is a feature that interrupts regular Mix Minus outputs
with a mono line level signal inputted at each submaster module’s
rear panel upper DB-25 (“A”) audio connector. Individual inter-
rupts are controlled by eight MIX MINUS CONFIDENCE FEED
switches on a separate module. A ninth MASTER switch will
interrupt all eight feeds simultaneously.
