Timer Restart
When the module is turned ON the console’s digital timer can be
programmed to automatically reset to zero and being counting up.
SW15 Position 3 activates Timer Restart when mic A is turned ON
SW16 Position 7 activates Timer Restart when mic B is turned ON
Phantom Power
Positions 1 and 2 of seven-position dipswitch SW6 turn phantom
power on (UP position) and off (DOWN position). Position 1 controls
microphone input A, and position 2 microphone B.
Hook-Ups
As stated before, all user wiring to and from ML-7000 modules is
done via two DB-25 multi-pin connectors located in the bottom of the
console’s mainframe, directly underneath each individual module, and
one DB-9 connector mounted on the console’s motherboard. A pinout
drawing on page 2-11 shows all wiring connections at a glance.
Audio Connections
Upper DB-25 Connector
These include A and B mic/line inputs, and insert in and out. The mic
input level is nominally -50dBu, line input and in/out insert points level
are +4dBu balanced. All signals are analog mono.
