There are 16 rotary knobs on the front panel.

The rotary knobs can be used to adjust the parameters of the selected audio function.
Each input channel has a green "ON" LED and a red "PEAK" LED. "ON" lights up when the
input channel is connected. "ON" remains illuminated if the automix function is switched off.
"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 gain control on the rear panel of the connected unit.
NOTE
MUTE function:
Briefly pressing a rotary knob causes the corresponding channel to be muted. The MUTE
function is indicated by the steady flashing of the LED rings. Another brief press of the rotary
knob removes the MUTE function.
VU function:
NOTE
The "SYSTEM CONTROL" rotary knob can be used to display the current audio level of the
inputs, see DMM 12BC operation.
Inputs
The DMM 12BC has 12 balanced input channels for connecting low-impedance dynamic or
condenser microphones and other audio sources, e.g. receivers for wireless microphones. A
rotary knob is available for each input channel. These are labelled "IN 1" to "IN 12".
Operating mode / system control
The DMM 12BC has a large number of functions, such as volume, treble ranges, bass, auto-
mix functions, etc. The "SYSTEM CONTROL" rotary knob can be used to select these
functions.
Stereo outputs
The rotary knobs for the stereo output channels are labelled "OUT 1" and "OUT 2". These
rotary knobs adjust the volume, treble and bass range, limiting behaviour, balance and delay
in the output channels.
Control display for stereo outputs
The control displays under the rotary knob for the stereo output channels indicate the output
level in dB.
Stereo headphone output
Both the inputs and outputs can be monitored on the stereo headphone output. Hold down the
"HEADPHONE" rotary knob and select another monitor source by pressing another rotary
knob. You can monitor several sources with inputs. In mono, they are simultaneously switched
to the left and right headphone channel. The output can only monitor individual sources, but in
stereo. The previous monitoring source is switched off by pressing on another source (switch
between inputs and output). The output "REC (OUT)" cannot be monitored.
