Configuring DMM 4/2/2

D D MM 4/2/2
The DMM 4/2/2 has a single master bus, to which the input channels are mixed and picked
up at the output channels. The unit is therefore mono in its internal structure.
Some of the individual input and output channels have configuration options which are set via
DIP switches. Other settings for the input and output channels are adjusted using the rotary
controls. The function to be changed is set using the "SYSTEM CONTROL" rotary control. If a
function selected in this way can be changed on an input or output channel, at least one LED
will light up on its LED ring.
Furthermore, the "SYSTEM CONTROL" rotary control can be used to display the audio level on
the inputs and outputs, see Operating DMM 4/2/2 (Page 38).
The default position of the "SYSTEM CONTROL" rotary control is the "LEVEL" setting. If this
control is set to another property, and no settings are carried out on any of the rotary controls
for more than 30 seconds, the "SYSTEM CONTROL" rotary control automatically returns to the
"LEVEL" position.
Please read the instructions for connecting your microphones and auxiliary equipment under
Installation and Connection (Page 35).
NOTE
Configure the connected microphones and auxiliary equipment using the DIP switches on the
rear panel of the DMM 4/2/2:
1) If you use condenser microphones, check what supply voltage or what type of power
supply they require. If your condenser microphones are suitable for phantom power,
switch on the phantom power. To do so, set the "Phantom Pwr" DIP switch to "ON".
If you are using wireless microphones, it is essential to switch off the phantom power on those
inputs to which you have connected a receiver, in order to avoid damaging the receiver.
ATTENTION
2) Use the "Line/Mic" DIP switch to set the preamp to "Mic" if you are using a microphone,
and to "Line" if you are using other connected audio sources, such as receivers for
wireless microphones.
3) For the gain of the input signals, choose between +40 dB and +60 dB. To do so, set the
DIP switch to "Mic-Lo" or "Mic-Hi".
The setting "Mic-Hi" results in a greater gain of the input signals. This setting is suitable for
microphones with a low output level.
For microphones with a high output level the "Mic-Lo" setting is recommended.
NOTE
4) Turn the unit on with the power switch.
