1 Operating Elements
and Connections
1.1 Input channels
Fig. 1 Mono input channel CH 1; the other mono
input channels are identical.
Fig. 2 Stereo input channel CH 9 /10; with the
exception of the button of item 19, the second
stereo input channel is identical.
1 Channel fader to adjust the volume of the
channel and to fade in / fade out the channel
signal
2 Button SOLO to monitor the selected channel
via the headphones connected to the jack
PHONES (52) and via a monitor system con-
nected to the jacks BOOTH OUT (53):
either for pre-fader listening when the button
PFL/AFL (40) is disengaged
or for controlling the overall channel adjust-
ment after the channel fader when the button
PFL/AFL is pressed
When the button SOLO is pressed, the corre-
sponding LED PEAK (5) will light perma-
nently and the level indicators (38) will indi-
cate the corresponding channel signal.
3 Button L-R: When the button is pressed, the
channel signal will be added to the sum chan-
nels MASTER. With the control PAN (7) or
BAL (8), the signal can be added to the right
or to the left channel only or to both channels.
4 Button 1-2: When the button is pressed, the
channel signal will be added to the subgroups
SUB 1 and SUB 2. With the control PAN (7) or
BAL (8), the signal can be added to group
SUB 1 or SUB 2 only or to both groups.
5 LED PEAK: When the button SOLO (2) is
pressed, the LED PEAK will light perma-
nently. When the button SOLO disengaged,
the LED PEAK will light up briefly to indicate
that the maximum undistorted signal level
has been reached. If it lights up longer, the
channel is overloaded. In this case, turn back
the control GAIN (20) accordingly.
6 Button MUTE (with LED indicator) to mute
the channel
7 Panorama control PAN to place the mono
signal in the stereo sound
When the button 1-2 (4) is pressed, the con-
trol PAN can be used to assign the channel
signal to the subgroups.
8 Balance control
When the button 1-2 (4) is pressed, the bal-
ance control can be used to assign the chan-
nel signal to the subgroups.
9 Control AUX SEND 2 / FX to add the channel
signal to send way 2 (post-fader); this send
way is also used as an effect way for the
internal effect processor
10 Selector button PRE for send way 1
disengaged: signal picked-up post-fader
The channel signal is fed to the send way
after the fader (1).
pressed: signal picked up pre-fader
The channel signal is fed to the send way
ahead of the fader.
11 Control AUX SEND 1 / MON to add the chan-
nel signal to send way 1
12 Equalizer control LOW 80 Hz for the bass fre-
quencies:
±15 dB at 80 Hz
13 Equalizer control MID for the mid-frequencies:
±15 dB at 100 Hz - 8 kHz
14 Equalizer control MID 500 Hz for the mid-fre-
quencies at 500 Hz: ±15 dB
15 Control MID FREQ to adjust the filter fre-
quency (100 Hz - 8 kHz) for equalizer control
in the midrange
16 Equalizer control MID 3 kHz for the mid-fre-
quencies at 3 kHz: ±15 dB
17 Equalizer control HIGH 12 kHz for the high
frequencies: ±15 dB at 12 kHz
18 Button
for the low cut filter (high pass fil-
ter):
When the button is pressed, unwanted signal
parts below 75 Hz (e. g. impact noise) will be
suppressed.
19 Channel CH 9 /10:
Button +4/-10 for matching the level of units
with low output level; when the button is
pressed, the input level will be boosted
Channel CH 11/12:
Button LINE / OPT to switch the channel input
disengaged: input = jacks LINE (21)
pressed: input = signal of an additional mod-
ule (e. g. MP3 player) which is installed in
the upper right section instead of the cover
panel
20 Control GAIN to adjust the input amplification
21 Input LINE (6.3 mm jack, bal.) to connect a
signal source with line output level (e. g.
musical instrument, CD / MP3 player)
Note with regard to the stereo channels: When con-
necting a mono unit, only use the jack L. The signal
will then be internally sent to the right and left chan-
nels.
22 Input MIC to connect a microphone
(XLR jack, bal.)
A phantom power can be activated for all
microphone inputs,
item 49.
23 Input and output jacks (RCA) TAPE for a
recorder
The sum signal is available at the jacks OUT
[after the faders MASTER (34)].
When the button TAPE / USB TO MIX (41) is
pressed, the signal of the jacks IN will be
added to the sum signal ahead of the faders
MASTER.
1.2 Output panel
24 Faders for the subgroups 1 and 2
25 Buttons MUTE (with LED indicator) to mute
the subgroups
26 Assign buttons SUB ASSIGN TO MASTER to
forward the subgroup signals to the left or/
and right sum channel
27 Level control FX RETURN for the effect sig-
nal of the internal effect processor or for the
signal at the input FX RETURN (57)
Use the level control to add the signal to the
sum channels MASTER.
28 Level control AUX SEND MASTER 2 / FX for
the total signal of send way 2 that is sent to
the internal effect processor and to the output
AUX SEND 2 (55)
29 Button SOLO - one for send way 1 and one
for send way 2 - to monitor the send way via
the headphones connected to the jack
PHONES (52) and via a monitor system con-
nected to the jacks BOOTH OUT (53)
30 Level control AUX SEND MASTER 1 / MON
for the total signal of send way 1 that is avail-
able at the output AUX SEND 1 (55)
