Description
Analogue control
Figure 11: Phoenix terminal
A linear 50 kOhm potentiometer at the VCA input, labelled "VCA" and "", 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.
