Superphone Output Assign
MMD-5 output assign switches can slave off the console’s SPD-5
superphone telephone input module output assign switches.
Example: you are running a call-in show with three studio guests, each with
his own microphone and MMD-5 input module. You set up the caller and are
ready to go live. By pre-programming your studio guests’ mic inputs to follow
the superphone module’s output assign switch (or switches), all you need do is
press the PGM assign button on the phone module; PGM assign switches on
guest inputs will simultaneously be activated. Thus, the entire segment can go
live with the press of one button.
Dipswitch SW2 on the MMD-5 module (to the left of the fader) will
slave selected output assign switches to follow superphone output assign
control pulses:
Dipswitch position 1 links the PGM switch
Dipswitch position 2 links the AUD switch
Dipswitch position 4 links the UTL switch
In order for this feature to work, an associated dipswitch on the
superphone module PCB (SW1) must be programmed as well (see page
9-4).
Hook-Ups
As stated before, all user wiring to and from MMD-5 modules takes
place at AMP 12-pin connectors mounted directly beneath each module
on the console mainframe’s bottom pan. There are four connectors per
module: A and B (towards the console meterbridge) handle audio signals;
C and D (near the console armrest) control signals.
Audio Connections (AMP A, B).
These include A and B mic inputs, and insert in and out. The mic input
level is nominally -50dBu. Insert points are +4dBu balanced in and out.
All signals are analog mono.
Pin 1 – Mic A In SH
Pin 3 – Mic A In HI
Pin 2 – Mic A In LO AMP A connector
Pin 4 – Mic B In SH
Pin 6 – Mic B In HI
Pin 5 – Mic B In LO
Pin 7 – Insert Out SH
Pin 9 – Insert Out HI
Pin 8 – Insert Out LO AMP B connector
Pin 10 – Insert In SH
Pin 12 – Insert In HI
Pin 11 – Insert In LO
Note the insert points are normally bypassed by PCB-mounted slide
switch SW7 (see page 2-3). Regardless of this switch setting, the Insert
Out pins may be used as a channel direct output if desired.
Note this feature only
works for turning assign
switches ON; they will not
turn OFF from the
superphone module—this
must be done manually.
