Led Level indicator - Vu meter
It indicates the output signal level . For a correct amplifier volume use, the volume level must be set

Inputs INPUT1 ~ INPUT4:
a. COMBO/XLR Input connector
b. Euro block terminal – can be removed
c. Dip-switch:
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
