8. External control inputs
This is a 15-pin sub-D socket on the device back, labelled “EXT.CONTROL”.
Remote volume control
(see heading 8a)
Through the external control input, a simple remote volume control can be implemented. The
eight control inputs can be connected to external potentiometers or 0–10 V DC control
voltages. The input and output channels controlled with the remote function are user-
definable (see software manual).
Configuration switching
(see heading 8b)
The control inputs for configuration switching are also contained in this port. With external
switching contacts, one of up to then defined configurations can be activated.
Pin assignment:
1: External1 9: External2
2: External3 10: External4
3: External5 11: External6
4: External7 12: External8
5: +10 V 13: GND
6: Config.1 14: Config.2
7: Config.4 15: Config.8
8: GND
