GAIN
Use the GAIN control to adjust the input gain. This control should always be 

turned fully counter-clockwise whenever you connect or disconnect a signal 

source to one of the inputs. 
The scale has 2 different value ranges: the first value range (+10 to +60 dB) 

refers to the MIC input and shows the amplification for the signals fed in there.
The second value range (+10 to -40 dB) refers to the line input and shows 

its sensitivity. The settings for equipment with st andard line-level signals 

(-10 dBV or +4 dBu) look like this: While the GAIN control is turned all the way 

down, connect your equipment. Set the GAIN control to the external devices’ 

standard output level. If that unit has an output signal level display, it should 

show 0 dB during signal peaks. For +4 dBu, turn up GAIN slightly, for -10 dBV 

a bit more. Fine-tuning of a signal being fed in is done using the level meter. 

To route the channel signal to the level meter, you have to press the SOLO switch 

and set the MODE switch in the main section to PFL (LEVEL SET).
Using the GAIN control, drive the signal to the 0-dB mark. This way you have 

a vast amount of drive headroom for use with very dynamic signals. The CLIP 

display should light up only rarely, preferably never. While fine-tuning, 

the equalizer should be set to neutral.

LOW CUT
Additionally, the mono channels of the mixing consoles have a high-slope 

LOW CUT filter for eliminating unwanted, low-frequency signal components 

(75 Hz, 18 dB/octave).

2.1.2  Equalizer
All mono input channels have a 3-band equalizer with semi-parametric mid 

bands. All bands provide boost or cut of up to 15 dB. In the central position, 

the equalizer is off (flat).

All Models

Fig. 2.2: Equalizer of the input channels

The upper (HIGH) and the lower (LOW) bands are shelving filters that increase 

or decrease all frequencies above or below their cut-off frequency. The cut-off 

frequencies of the upper and lower bands are 12 kHz and 80 Hz respectively. 

For the mid range, the console features a semi-parametric equalizer with a 

filter quality (Q) of 1 octave, tunable from 100 Hz to 8 kHz. Use the MID control 

to set the amount of boost or cut, and the FREQ control to determine the 

central frequency.

Fig. 2.3: Aux Send control MON and FX in the channel strips

Monitor and effects busses (AUX sends) source their signals via a control from 

one or more channels and sum these signals to a so-called bus. This bus signal is 

sent to an aux send connector (for monitoring applications: MON OUT) and then 

routed, for example, to an active monitor speaker or external effects device. 

In the latter case, the effects return can then be brought back into the console via 

the aux return connectors.
All monitor and effects busses are mono, are tapped into post EQ and offer 

amplification of up to +15 dB.

Pre-fader/Post-fader
When using effects on a channel signal, it is usual to have the aux send post 

fader so that the balance between effect and dry signal stays constant even 

when the channel fader is altered. If this were not the case, the effects signal of 

the channel would remain audible even when the channel fader is turned all the 

way down. For monitoring, the aux sends are generally pre-fader, i.e. they operate 

independently of the position of the channel fader.

PRE
When the PRE switch is pressed down, the associated aux send is taken 

pre-fader.

FX
The aux send marked FX offers a direct route to the built-in effects processor and 

is therefore post-fader and post-mute. Please refer to chapter 4 “Digital Effects 

Processor” for detailed information.
