connectionS, CONtROLS, AND INDICAtORS:
1 MIC / LINE IN 1
Balanced microphone or line input (XLR / 6.3 mm jack combo socket).
Connect a microphone (dynamic or condenser) using an XLR microphone cable. The XLR input
features 20 V DC phantom power. When connecting a condenser microphone, please observe its
operating voltage. A mono line signal source can be connected both via a balanced jack cable
(6.3 mm stereo jack) as well as via an unbalanced jack cable (6.3 mm mono jack).
2 tRIM KNOB
Use the TRIM knob to set the input amplification (gain). If you want to connect signal sources to or
disconnect them from the mixer, the corresponding TRIM knob should always be set to minimum
(knob all the way to the left).
The associated scale shows two different value ranges: The first value range (0 to +50 dB) refers
to the MIC input and the gain of the corresponding signal. The second value range (+10 to -40
dB) refers to the line input and indicates the respective sensitivity.
To attain optimal modulation, it is advisable to turn the TRIM knob up until the clip LED (3) flashes
only when level peaks occur in the connected signal.
3 CLIP LED
Lights up as soon as the level of the connected signal is only 3 dB below the clipping threshold.
4 2-BAND EQUALIZER
The high band (HIGH) is at 12,000 Hertz. The associated control makes it possible to boost or cut
treble frequencies by up to 15 dB.
The bass band (LOW) is at 80 Hertz. The associated control makes it possible to boost or cut bass
frequencies by up to 15 dB.
In the centre position, the signal remains unprocessed; the equalizer is inactive.
5 PAN
The panorama control lets you set the position of the connected signal in the stereo field.
6 LEVEL
Use the LEVEL control to set the level of the respective channel strip in the master mix.
7 LINE IN 2/3
The stereo channel is a line input that has two unbalanced RCA sockets (left/right) and is designed
for typical line-level signals.
8 BAL
Use the balance control to set the relative volume between the left and right channel of the
connected stereo signal.
