DMM 12BC 47
Description
Analogue control
Figure 11: Phoenix terminal
A linear 50 kOhm potentiometer at the VCA input, labelled "VCA" and "A", allows you to vary
the master volume.
Figure 12: VCA
The linear potentiometer is connected to the VCA input as shown above. The resistance at the
VCA input is changed by turning the potentiometer. This value is input and the volume is
changed accordingly. The left setting signifies 0% while the right setting signifies 100%.
The output level depends on the master control and the remote level control. The remote level
control has the same affect on both masters.
Digital output
Figure 13: Digital output
The DMM 12BC has a digital output which can be picked up via a balanced AES/EBU or an
optical S/PDIF output on the rear panel of the device. The AES/EBU output can be accessed
via a 3 pin Phoenix terminal. The assignment from left to right is a, b, shield. The optical
output is accessible via a TOSLINK socket.
Both digital outputs have the same data signal. The signal is in stereo, has a 24 Bit data
format and a sample frequency of 48 kHz.
The "ROUTING TO DIGOUT" function on the system control on the front panel can be used to
individually or jointly route the inputs.
Power switch
The power switch is used to turn on the unit.
