GB
Please read these operating instructions carefully
prior to operation and keep them for later reference.

1 Operating Elements and Connections

1 Mono input MIC IN (bal.) to connect a micro-
phone to channel CH 1 via XLR plug or 6.3 mm
plug
At the XLR jack, a phantom power of +18 V is
always present.
2 Stereo input LINE IN (RCA jacks) to connect an
audio source with line signal level (e. g. CD
player) to channel CH 2
3 Stereo input TAPE IN (RCA jacks) to connect the
output of a recorder
4 Stereo output TAPE OUT (RCA jacks) to con-
nect the input of a recorder
5 USB port (type B) to connect a computer or a
power supply unit with USB connection; when
operating the mixer with a computer, it is possi-
ble to use this port as an audio output (output of
the mixed signal) and as an audio input (feed-in
of audio data to be reproduced via channel
CH 2)

2 Applications
This compact 2-channel audio mixer with USB inter-
face is suited for universal applications, e. g. for
audio recording on the computer. The mono input
channel allows to connect a (phantom-powered)
microphone; the stereo input channel allows to con-
nect an audio source with line signal level. In addi-
tion, the mixer is provided with connections for a
recorder and headphones. The mixed signal is sent
to the output via a 3.5 mm jack and the USB port. It
is also possible to use the USB port as an input to
transfer audio data from the computer to the mixer.
When connecting the mixer to a computer, power
is supplied via the USB connection. When operating
the mixer without a computer, either use a suitable
power supply unit with USB connection or operate
the mixer via the integrated rechargeable lithium-
ion battery. The battery is charged when the mixer
is connected to the power supply via the USB port.
3 Important Notes
This unit corresponds to all relevant directives of the
EU and is therefore marked with
G
The unit is suitable for indoor use only. Protect it
against dripping water and splash water, high air
humidity and heat (admissible ambient tempera-
ture range 0 – 40 °C).
G
For cleaning only use a dry, soft cloth; never use
water or chemicals.
G
No guarantee claims for the unit and no liability
for any resulting personal damage or material
damage will be accepted if the unit is used for
other purposes than originally intended, if it is not
correctly connected or operated, or if it is not re-
paired in an expert way.
If the unit is to be put out of operation
definitively, take it to a local recycling
plant for a disposal which is not harmful to
the environment.

4 Audio Connections

Prior to connection, always turn back the output
controls MONITOR / PHONES (10) and MASTER
(14) to "0".
1) The input MIC IN (1) of the mono channel CH 1
allows to connect a microphone via XLR plug or
6.3 mm plug. Both the XLR jack and the 6.3 mm
jack of the combined jack are balanced.
The XLR jack always supplies a 18 V phantom
power and it thus suitable for a condenser micro-
phone operated with this phantom power.
Caution! Do not connect a microphone with
unbalanced output via XLR plug; it my be dam-
aged by the phantom power.
2) The input LINE IN (2) of the stereo channel CH 2
allows to connect an audio source with line sig-

nal level (e. g. CD player) via RCA plugs: L = left
channel, R = right channel.
3) It is possible to use the RCA jacks TAPE IN (3)
and OUT (4) to connect a stereo recorder:
– Connect the recording output of the recorder to
the input TAPE IN.
– Connect the recording input of the recorder to
the output TAPE OUT; the output signal ad -
justed with the MASTER control (14) is sent to
this output.
However, it is also possible to use the jacks for
other units with line signal level, e. g. to connect
a CD player or MP3 player to TAPE IN or to con-
nect an amplifier to TAPE OUT.
4) The 3.5 mm jack MONITOR / PHONES (9) allows
to connect stereo headphones (impedance ≥ 8 Ω).
Thus, you will be able to monitor the output sig-
nal adjusted with the control MASTER (14) or the
input signal of the jacks TAPE IN (3) via head-
phones.
5) At the stereo output MAIN OUT (7), the output
signal adjusted with the MASTER control (14) is
present. This output allows to connect e. g. an
amplifier or a second mixer via 3.5 mm plug.
6) When operating the mixer with a computer, it is
possible to use the USB port (5) for digital output
of the mixed signal to the computer and for feed-
ing digital audio data to the mixer. To connect the
port see chapter 5.1.
