Description

Front panel

30
The front panel contains a total of eight rotary controls.
1 to 4:
5, 6:
7:
8:
The rotary controls can be used to adjust the parameters of the selected audio function.
Each input channel has a green LED "ON" and a red LED "PEAK". "ON" lights up when the
input channel is connected. If the Automix function (see "Automatic mixing functions"
Page 34) is switched off, "ON" lights continuously. "PEAK" lights up when the signal on an
input channel is close to the maximum control limit. In this case, the level should be turned
down or the input sensitivity should be changed.
The input sensitivity is adjusted using the DIP switches (see "Input channels" Page 31) on the
rear panel of the connected unit.
NOTE
MUTE function:
Briefly pressing a rotary control causes the corresponding channel to be muted. The MUTE
function is indicated by the steady flashing of the LED ring. Another brief press of the rotary
control removes the MUTE function.
VU function:
NOTE
The "SYSTEM CONTROL" rotary control can be used to display the current audio level of the
inputs and outputs, see Operating DMM 4/2/2 (Page 38).

MIC/LINE inputs

The DMM 4/2/2 has four balanced input channels for connecting low-impedance dynamic or
condenser microphones and other audio sources, e.g. receivers for wireless microphones. A
rotary control is available for each input channel. These are labelled "IN 1 - MIC/LINE" to "IN 4
- MIC/LINE".

AUX inputs

The DMM 4/2/2 has two AUX inputs for connecting external audio sources, e.g. a CD player. A
rotary control is available for each input channel. These are labelled "IN 5 - AUX" and "IN 6 -
AUX".

Operating mode

The DMM 4/2/2 has a large number of functions (see "DSP functions" Page 39), such as
volume, treble ranges, bass, auto-mix functions, etc. The "LOCKED" function can be used to
lock the entire unit. These functions can be selected using the "SYSTEM CONTROL" rotary
control.

Output

The rotary control for the master output channel is labelled "OUT MASTER". This rotary control
is used to adjust the volume, treble, bass, limiting behaviour and attenuation on the output
channel.
