MONO MIC INPUT
Internal Programming Options
Internal programming is made via printed circuit board (PCB) mounted
switches on the module’s main card.
For the purposes of this manual, we will assume you are holding the
removed module upright, component side towards you, with gold-plated
card fingers to the left and the module faceplate to the right. This will
enable you to read the control legends silkscreened next to each program-
ming switch. Note when a dipswitch position is thrown to the right
(towards the module’s faceplate) it is ON.
Insert Bypass
SW2 (a double throw double pole slide switch right next to the card’s
short upper row of gold fingers) will click the module’s insert point in and
out of the audio signal chain. Note again that the factory default is “insert
bypassed”. In other words, when shipped from the factory SW2 is thrown
in the direction of the silkscreened arrow on the PCB (to the left). To use
the insert point (see “Audio Connections” page 2-4), throw the switch to
the right, towards the module faceplate.
Phantom Power
Four-position dipswitch SW1 (upper right corner of card) turns phan-
tom power on and off for the module’s two microphone input ports.
Dipswitch position 1 activates phantom power for microphone A
Dipswitch position 2 activates phantom power for microphone B
Talkback to Studio
One module in the console (typically the console operator’s micro-
phone) can be assigned to the console’s talkback bus to be the source for
talkback to studio. Dipswitch SW1 position 4 is used to assign the
module’s pre-fader audio to the talkback bus.
VDT Programming Options
Mutes, timer restart, tallies, talkback, superphone output assign, and
utility bus pre-fader programming are made via Virtual Dip Switch
Software (see Chapter 9).
Hook-Ups
As stated before, all user wiring to and from MMD-600 modules takes
place at DB-25 multi-pin connectors mounted directly beneath each
module on the console mainframe’s bottom pan. There are two connectors
per module: the upper one (towards the console meterbridge) handles
audio signals; the lower (near the console armrest) control signals. A
pinout drawing on page 2-6 shows all wiring connections at a glance.
Note the factory default
setting for phantom power
is OFF.
