NOTE
There are 16 rotary knobs on the front panel.
| Figure 1: Front panel of the DMM 12BC |
1 - 12: | Microphone or line inputs |
13: | Operating mode / system control |
14, 16: | Stereo outputs 1 and 2 |
15, 17: | Control display for stereo outputs 1 and 2 |
18: | Headphone output |
19: | Headphone connection |
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.
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:
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
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.
