5 Setting the Mixer into Operation

5.1 Operation with a computer

When operating the mixer with a computer, either
use the audio software supplied with the operating
system or an audio software installed additionally.
Various programs for audio reproduction / recording
are available on the Internet free of charge.
1) Start the computer. Connect the USB port (5) to
a USB connection on the computer via the USB
cable provided. Switch on the mixer with the
switch POWER (8) [position "ON"]. The LED ON/
CHARGE (6) lights up according to the battery
charge status ( chapter 5.3).
The computer recognizes the USB interface of
the mixer as an external device for audio input
and audio output, e. g. as "USB Ear-Micro-
phone", depending on the operating system. The
required drivers (standard drivers of the operat-
ing system) are available on the computer.
Note: If not all drivers required are available on the com-
puter, install them, e. g. via the original CD of the operat-
ing system. Restart the computer after installation, if nec-
essary.
2) Open the reproduction / recording program and
make the required settings for audio reproduc-
tion via the mixer or audio recording from the
mixer ( user manual of the program). Then
operate the mixer according to chapter 6.
If it is not possible to record or reproduce any
sound, make sure to activate the USB interface for
audio input or audio output in the system settings of
the operating system of the computer.
Hint: If the mixer is connected to a computer and to any units
earthed via their mains cables (e. g. amplifiers), there may
be hum noise due to ground loops. To eliminate this noise,
connect the mixer to the corresponding unit via a ground iso-
lator (e. g. FGA-30 from MONACOR).
5.2 Operation with power supply unit
Via its USB connection, the power supply unit must
provide an output voltage of 5 V
current of 500 mA (e. g. PSS-1000USB from
MONACOR). Connect the power supply unit to the
USB port (5) via the USB cable provided, then con-
nect it to a mains socket. Switch on the mixer with
the switch POWER (8) [position "ON"]. The LED
ON / CHARGE (6) lights up according to the battery
charge status ( chapter 5.3).
5.3 Charging the battery / Battery operation
To ensure the maximum operating time (approx.
4 hours) when the mixer is operated via the inte-
grated rechargeable lithium-ion battery, fully charge
the battery prior to operation. Connect the USB port
(5) to a computer (chapter 5.1) or to a power supply
unit (chapter 5.2). The LED ON / CHARGE (6)
shows the charge status and operating mode:
1. With the mixer switched off [switch POWER (8)
set to "OFF"], the LED ON / CHARGE shows
green while the battery is being charged. When
the battery has been fully charged, the LED is
extinguished.
2. With the mixer switched on [switch POWER set
to "ON" ], the LED ON / CHARGE shows red and
green (= yellow) at the same time while the bat-
tery is being charged. When the battery has been
fully charged, the LED shows red.
To save battery power, the LED ON / CHARGE does
not light up during battery operation. Therefore, you
may easily forget to switch off the mixer. To prevent
the battery from being completely discharged,
always make sure to set the switch POWER to
"OFF" after operation.
6 Operation
1) Switch on the mixer with the switch POWER (8)
[position "ON"].
2) For basic setting, set the controls MASTER (14)
and GAIN (15) approximately to mid-position for
the time being.
3) When a microphone is connected to the jack MIC
IN (1), speak into the microphone and turn up the
corresponding control LEVEL (17) until you
obtain a good microphone signal. If you need to
turn up the control LEVEL completely for this pur-
pose, further turn up the control GAIN (15). How-
ever, if the LED PK (19) lights up and is not extin-
guished immediately, turn back the control GAIN.
The LED PK must only briefly light up with level
peaks.
4) Use the panorama control PAN (18) to place the
microphone signal on the stereo base. Adjust the
sound with the controls HI and LO (16).
5) Turn up the control LEVEL (21) for channel CH 2
until you obtain a good input signal.
To assign the input signal of the USB port (5)
to channel CH 2, press the button USB ASSIGN
TO CH 2 (23). When the button is engaged, the
USB input signal and the signal of the input LINE
IN (2) use the same channel. Therefore, do not
use the input LINE IN if you intend to reproduce
only the USB input signal via channel CH 2.
Note: When recording via the USB port, please pay
attention to the risk of feedback if you assign the record-
ing signal of the computer to channel CH 2 as an input
signal.
6) For channel CH 2, adjust the sound with the con-
trols HI and LO (20) and the balance with the
control BAL (22).
7) Use the controls LEVEL (17, 21) to mix the input
signals of channels CH 1 and CH 2 or to fade
them in and out. When a channel is not used, set
its control to "0".
8) Use the control MASTER (14) to set the level of
and an output
the output signal that is sent via the jacks MAIN
OUT (7), TAPE OUT (4) and the USB port (5). If
one of the overload LEDs CLIP (13) shows red,
turn back the control MASTER accordingly.
9) The headphone output MONITOR / PHONES (9)
allows to monitor the output signal of the mixer.
For this purpose, the button TAPE IN ASSIGN
TO MONITOR (12) must not be engaged. Adjust
the headphone volume with the control MONI-
TOR / PHONES (10).
WARNING! Never adjust the headphones to a
very high volume. Permanent high volumes
may damage your hearing! Your ear will get
accustomed to high volumes which do not
seem to be that high after some time. There-
fore, do not further increase a high volume after
getting used to it.
10)When a unit is connected to the jacks TAPE IN
(3), it is possible to monitor the output signal of
this unit:
1. If the button TAPE IN ASSIGN TO MAIN (11) is
engaged: via the outputs MAIN OUT (7), TAPE
OUT (4), USB (5) and MONITOR / PHONES
(9). The output signal of the mixer is also pres-
ent at these jacks. Therefore, set the two con-
trols LEVEL (17, 21) to "0", if necessary.
2. If the button TAPE IN ASSIGN TO MONITOR
(12) is engaged: only via the headphone out-
put MONITOR / PHONES. In this case, it is not
possible to monitor the output signal of the
mixer via the headphone output.
