MIC CHANNEL 17/18 AND 19/20
Balanced inputs of the channels 17/18 and 19/20 with 3-pin XLR sockets for connecting microphones.
Channels 17/18 and 19/20 can be used as both mono and stereo channels, depending on the incoming
signal (XLR and jack L IN = Mono / jack L and R IN = Stereo). A 48 V phantom power supply is available for
operating condenser microphones, and it can be switched centrally to the XLR sockets (N° 3). Please set the
Gain controller (N 41) to minimum (left stop) before connecting or disconnecting a microphone; and switch
on the phantom power only after connecting the microphone, or off before disconnecting.
