PIN1 position ON=Input for a signal- Micro level
position OFF=input for a signal-.LINE level
PIN2 position ON = Input direction is inverted
PIN3 position ON = High pass filter – active in input (ideal for speech)
position OFF = on input no filter action
PIN4 position ON = Phantom 48V active
position OFF = Phantom 48V not active
When INPUT1 is active , the unit makes in Mute status all other signal sources
