Control concept

There are 16 rotary knobs on the front panel. These are labelled "IN 1" to "IN 12", "SYSTEM

 

 

CONTROL", "OUT 1", "OUT 2" and "HEADPHONE".

 

 

The rotary knobs on the inputs are each surrounded by an LED ring with 15 yellow LEDs, one

 

 

green LED and one red LED. The rotary knob "SYSTEM CONTROL" and the rotary knobs on

 

 

the outputs are surrounded by 15 yellow LEDs. The control display under the outputs has 6

 

 

green, one yellow and one red LED.

 

 

The LED rings help to visualise the rotary knob setting or display signal levels.

Configuring DMM 12BC

 

 

 

 

 

 

 

 

Please read the instructions for connecting your microphones and auxiliary equipment under

 

 

 

Installation and Connection (Page 49).

 

 

 

NOTE

 

 

 

Configure the connected microphones and auxiliary equipment using the slide switches and

 

 

the gain controls on the rear panel of the DMM 12BC:

 

 

1) If you use condenser microphones, check what supply voltage or what type of power

 

 

supply they require. Switch on the phantom power if your condenser microphones are

 

 

suitable for phantom power. To do so, set the "PHANT. PWR" slide switch to "ON".

 

 

 

 

 

Risk of damage

 

 

 

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) For the gain of the input signals, choose between 0 dB and +57 dB. Use the respective

 

 

gain control to do so.

 

 

 

A higher gain of the input signals is suitable for microphones with lower output levels.

 

 

A lower gain is recommended for microphones with a high output level.

NOTE

3)Turn the unit on at the power switch.

DMM 12BC operation

The rotary knobs on the front panel of the DMM 12BC are operated as follows:

Figure 15: Operation of the rotary knob

Turn the rotary knob clockwise or counter-clockwise to make changes to inputs and outputs and function settings. These changes are shown on the LED ring around the rotary knob. The starting point and the increments on the LED ring will vary according to the function.
