Module Servicing
Input modules can be removed and installed
with the console powered and on-air without caus-
ing audio interruption or noises in the program
audio. When first plugged in, or when the console
is first turned on, Input modules come up in their
default turn-on state—no bus assignments active,
the module in the Off state.
Note
: Prior to removing any module from the
motherboard, turn off all bus assignments and un-
plug all input, output and logic cables.
To remove a module from the mainframe:
1.
Loosen the knurled captive fastener at the
top of the module.
2.
Remove the 4-40 button head faceplate
screw at the bottom of the module. The Air-
Wave Digital Tool kit includes the hex driver.
3.
Use the knurled captive fastener to unplug
the module from the motherboard and re-
move it from the mainframe.
To install a module:
1.
Set the module’s faceplate on the front chas-
sis module mounting tab.
2.
Lower the module into the mainframe and
align the module’s connector with the
motherboard connector.
3.
Once the connectors start to mate, press
straight down on the module’s faceplate
above the motherboard connector area to
seat the module. Do not press on buttons or
connectors while seating the module.
MODULE DISASSEMBLY &
REASSEMBLY
A module consists of a faceplate (the silk-
screened metal panel) and a circuit board. There
are two circuit boards on the double-width Moni-
tor module. There may also be one or more switch-
boards and a fader, as on the Input and Telco mod-
ules, or several potentiometers, as on the Monitor
module, plugged into the circuit board.
Circuit boards fasten to the faceplate using flat
head Phillips screws. Faders fasten to the faceplate
using 1/16 inch button head screws and plug into
a circuit board connector. Pots mount to the face-
plate using lock washers and nuts and plug into
circuit board connectors. The On and Off switches
mount on the On/Off switchboard. The Talkback
switch mounts on the Talkback switchboard. Both
of these switchboards use a flat cable and circuit
board connectors. The Assignment switchboards
and the Input module SIM (Single In-line Mod-
ule) mount in SIM sockets on the circuit board.
