Pin-Assignment Of XLRF-Type Connectors:
The pin-assignment of the MIC/LINE input's XLRF-type connector is as follows: pin 1 = screen, pin 2 = positive
conductor, pin 3 = negative conductor. In unbalanced configuration, the pins 3 (-) and 1 (screen) have to be
bridged inside the connection plug.

Internal Settings:
1. AUX input sensitivity
The input levels can be set in a range of -10 dBu to +12 dBu using trimmers VR2 (AUX 1) and VR3 (AUX 2).
The trim-potentiometers’ coarse scales are meant for your convenience, helping you in adjusting the levels.
