1 Operating Elements and Connections

1 On / off switch of the phantom power (+48 V) for the
XLR jacks (5) of channels CH 1 and CH 2
also see warning notes in chapter 4
2 POWER switch of the mixer
3 Power supply jack for connection of the power sup-
ply unit provided
4 USB jack (type B) for connection to a computer: it
can be used both as an audio output (output of the
sum signal) and as an audio input (feed-in of audio
data for reproduction via channel CH 5 / 6)
5 Mono input (combined jack XLR, bal. / 6.3 mm jack,
unbal.) for channel CH 1 and channel CH 2, for
connection of a microphone via an XLR plug or an
audio source with line signal level via a 6.3 mm plug
6 Impedance switch, for channel CH 1 and channel
CH 2: press the button when an electric guitar or an
electric bass with passive audio pick-up has been
connected to the 6.3 mm jack (5)
7 Stereo input (6.3 mm jack, bal.) for channel CH 3 / 4
for connection of an audio source with line signal
level; when connecting a mono source, use jack L
only.
8 Stereo input (RCA) for channel CH 5 / 6 for connec-
tion of an audio source with line signal level
9 Stereo input (RCA) for connection to the output of
a recorder
10 Stereo output (RCA) for connection to the input of
a recorder
11 Stereo output (6.3 mm jack, unbal.) for connection
of an amplifier or another unit, e. g. a second mixer
12 Output (6.3 mm jack) for connection of stereo
headphones (minimum impedance 8 Ω) for moni-
toring the sum signal [independent of the master
control (29)] or the signal at the input TAPE IN (9)
13 Button to switch the input signal of the USB jack (4)
to channel CH 5 / 6
14 Button to switch the signal of the input TAPE IN (9)
to the sum signal
15 Button to switch the signal of the input TAPE IN (9)
to the headphone output (12)
16 Control to adjust the input amplification, for channel
CH 1 and channel CH 2
17 Equalizer to adjust the high frequencies (HI) and
low frequencies (LO), for each input channel
18 Effect control, for each input channel, to adjust the
effect component for each channel
19 Panorama control, for channel CH 1 and channel
CH 2, to place the mono signal in the stereo sound
20 Balance control, for channel CH 3 / 4 and channel
CH 5 / 6
8
21 Level peak indication, for channel CH 1 and chan-
nel CH 2
22 Level control, for each input channel
23 Effect level control to add the effect signal to the
sum signal
24 Volume control for the headphone output (12)
25 Rotary switch to select the effect
26 Control indication for the phantom power
also see item (1)
27 POWER ON indication
28 Stereo level indication for the sum signal adjusted
with the master control (29); in case of overload the
CLIP LEDs light up
29 Overall level control (master control): defines the
level of the sum signal sent via the outputs MAIN
OUT (11), TAPE OUT (10) and the USB jack (4)

2 Safety Notes

The units (mixer and plug-in power supply unit) corre-
spond to all relevant directives of the EU and are there-
fore marked with .
WARNING The power supply unit is supplied with
hazardous mains voltage. Leave serv-
icing to skilled personnel only. Inexpert
handling or modification of the power
supply unit may cause an electric shock
hazard.
It is essential to observe the following items:
G
The units are suitable for indoor use only. Protect
them against dripping water and splash water, high
air humidity, and heat (admissible ambient tempera-
ture range 0 – 40 °C).
G
Do not place any vessels filled with liquid, e. g. drink-
ing glasses, on the units.
G
The heat being generated in the mixer must be car-
ried off by air circulation. Therefore, the air vents at
the housing must not be covered.
G
Do not set the mixer into operation, and immediately
disconnect the power supply unit from the mains
socket if
1. there is visible damage to the mixer or the power
supply unit,
2. a defect might have occurred after a drop or simi-
lar accident,
3. malfunctions occur.
The units must in any case be repaired by skilled
personnel.
G
For cleaning only use a dry, soft cloth, never use
chemicals or water.
G
No guarantee claims for the units and no liability for
any resulting personal damage or material damage
will be accepted if the units are used for other pur-
poses than originally intended, if they are not cor-
