Signal Path Insert Points
This TV-80 audio console is equipped with insert patch
points on the following modules:
Submasters
AUX master signals
SUBMASTER signals
Stereo Masters
STEREO MASTER output signals
These patch points can be bypassed by internal PCB-
mounted jumpers. As shipped from the factory, PCB-
mounted insert jumpers have already been installed. If
you intend to use outboard signal loops at these
points, you must remove the factory installed jumpers.
See “Submaster Module Insert Bypass” (Chapter 3)
and “Master Insert Bypass” (Chapter 4) in the TV-80
Technical Manual for details.
NOTE: While input modules also have insert points, these may simply be front panel
bypassed by an “insert” switch at the top of each module.

ATTENTION!
If your Wheatstone audio console has been ordered
and shipped with a failsafe power supply system, it
uses TWO separate rackmount power supplies. Though
either is capable of running the console on its own, in
failsafe operation both units run in tandem: if one fails,
the other takes over, assuring uninterrupted console
operation.
Dual failsafe supplies have their output trimmed to
entirely different settings than stand-alone single units,
and are MEANT to be run in tandem. If they are not, and
you attempt to “save” one supply by powering it down and
holding it in reserve until you run into an actual failure
condition, you could shorten the life expectancy of the
working unit.
!
In order for the failsafe system to perform as
designed, always have BOTH rackmount
supplies powered up and connected to the
console.

ATTENTION!
Wiring Power Supplies into AC Line
To insure proper power sequencing in systems
using an Event Computer, we recommend that the
PSC-125 Event Computer Power Supply be connected
to the same AC power circuit as the TV-80 PSC-1000
ConsolePowerSupply.
Further, if you have failsafe power supply pairs and have
connected each PSC-1000 to its own separate AC power
circuit, as recommended elsewhere in this manual, we
recommend that you connect one PSC-125 to each of
those circuits.

at the top of page 9-6 in your TV-80 Technical Manual
“Power Systems” chapter.

E X T R A C T O R T O O L S
Your Wheatstone TV-80 audio console is equipped with two
"module extractor tools" which are mounted underneath the
console armrest, to the far right (just in front of the operator’s
mainframe headphone jack).
Main module faceplates are held into the console mainframe by three
fasteners: a lower rear panel screw (below the module’s I/O connectors,
located at the rear of the console beneath the meterbridge assembly) and
two faceplate mounting screws (top and bottom) located on the control
surface of the console. The faceplate mounting screws, when removed,
leave specially threaded holes that accept the two extractor tools.
To remove a module faceplate from the mainframe:
Remove the rear panel screw, then the front top and bottom mounting
screws. Remove the extractor tools from underneath the armrest, and
screw each tool into a module faceplate mounting hole. Use only four or
five turns (do not over-insert; you may damage the threaded mainframe
hole underneath). Using the extractor tools as handles, pull the module
straight up out of the mainframe.
