MIC IN 1 - 4 & 5/6 - 7/8
Balanced inputs of the channels 1 to 4, or 5/6 and 7/8 with 3-pin XLR sockets for connecting microphones. Channels 1 to 4 are mono
channels, the channels 5/6 and 7/8 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° 53). Please set the Gain controller (N 4) to minimum (left stop) before connecting or disconnecting a micro-
phone; and switch on the phantom power only after connecting the microphone, or off before disconnecting.
2
LINE IN CHANNEL 1 - 4
Balanced inputs of the mono channels 1 to 4 with 6.3 mm jack to connect a source device with a line level. Please set the Gain controller (N
4) to minimum (left stop) before connecting or disconnecting jack cables.
3
INSERT CHANNEL 1 - 4
3-pin 6.3 mm jack socket for inserting an external signal processing device (Compressor, Gate, etc.) in the respective mixer channel. A
special insert cable is required for the connection (Y-cable, 1 x stereo jack to 2 x mono jack or XLR). The assignment is as follows: TIP =
Send, RING = Return, SLEEVE = Masse.
4
GAIN CHANNEL 1 - 7/8
Adjusting the gain of the microphone input from 0 to 50 dB, or the sensitivity of the line input from +15 dBu to -35 dBu. Adjust the Gain
controller so that the peak LED of the corresponding channel only lights up briefly when signal peaks occur. Avoid the permanent lighting of
the peak LED by reducing the input gain or input sensitivity.
