1 Operating Elements and
Connections

1.1 Rear panel

A Power supply jack for connection of the
power supply provided
B On/off switch of the mixer
C* USB jack (type B) for connection to a com-
puter: can be used as an output (digital out-
put of the sum signal) and as an input (feed-
in of audio data)

1.2 Front panel

Mono input channel CH 1;
channel CH 2 is identical
Stereo input channel CH 3/4;
channel CH 5 / 6 is identical
1 Input for connection of a microphone (XLR
jack, bal.)
Note: A phantom power can be activated for the
microphone inputs:
item 21.
2 Input for the connection of a unit with line sig-
nal level (e. g. musical instrument)
Mono channel:
1 × 6,3 mm jack, bal.
Stereo channel:
1 × 6,3 mm jack, Left L, bal.
1 × 6,3 mm jack, Right R, bal.
Only use the jack L to connect a mono unit.
3 Control GAIN for input amplification
4 Equalizer for high range (HIGH), midrange
(MID) and bass range (LOW)
5 Control AUX SEND to add the channel signal
to the effect send way; the signal will be
picked up after the control LEVEL (8)
In the model MMX-22UFX, the effect send
way is also used as the effect way for the
internal effect processor.
6 Mono channel:
Panorama control PAN to place the mono
signal in the stereo sound
Stereo channel:
Balance control BAL for the stereo signal
7 LED indicator PEAK; lights up permanently
when the channel is overloaded (control
GAIN or equalizer advanced too much or sig-
nal level at channel input too high)
8 Level control LEVEL to add the channel sig-
nal to the signal sum
Master section
9 Input STEREO AUX RETURN (6.3 mm jacks
Left L /Right R, unbal.), can be used as an
input for an effect unit or for an additional
line audio source (for the model MMX-22,
only use the jack L to connect a mono unit;
for the model MMX-22UFX, use a Y cable to
connect a mono unit to both jacks)
Note for model MMX-22UFX: Connecting a unit to
the jacks will mute the outputs of the internal effect
processor.
10 Output AUX SEND (6.3 mm jack, unbal.) of
the effect send way, for connection to the
input of an effect unit
11 Output PHONES (6.3 mm jack) to connect
stereo headphones (minimum impedance of
8 Ω)
12 Output BOOTH OUT (6.3 mm jacks Left L /
Right R, unbal.) to connect the amplifier of a
monitor system in a separate control room
13 Output MASTER OUT for the sum signal
(6.3 mm jacks Left L /Right R, unbal.), e. g. to
connect the amplifier for PA applications or to
connect a second mixer
14 Input TAPE IN (RCA jacks Left L /Right R) to
connect the output of a recorder or another
reproduction unit, e. g. a CD player
15 Output TAPE OUT (RCA jacks Left L /Right R)
to connect the input of a recorder
16 Button TAPE[/USB*] TO BOOTH/PHONES:
with the button pressed, the input signal of
the jacks TAPE IN (14) and the USB jack (C)*
is sent to the monitoring outputs PHONES
(11) and BOOTH OUT (12) and indicated by
means of the LED level indicator (22)
17 Button TAPE [/USB*] TO MIX:
press the button to send the input signal of
the jacks TAPE IN (14) and of the USB jack
(C)* to the sum signal
18 LED POWER ON
19 Model MMX-22:
Level control AUX SEND MASTER for the
sum signal of the effect send way at the out-
put AUX SEND (10)
Model MMX-22UFX:
Level control AUX RETURN for the output sig-
nal of the internal effect processor or the sig-
nal at the input STEREO AUX RETURN (9)
20 LED indicator; lights up when phantom power
has been activated by means of the button
PHANTOM 48V (21)
21 Button PHANTOM 48V: press the button to
apply a phantom power of 48 V to the inputs
MIC (1)
Please observe the warning notes with re -
gard to the phantom power in chapter 4.1.1.
22 LED level indicator for the sum signal or,
with the button TAPE[/USB*] TO BOOTH/
PHONES (16) pressed, for the input signal of
the jacks TAPE IN (14) and the USB jack (C)*
23 Volume control BOOTH/
for the monitoring
outputs PHONES (11) and BOOTH OUT (12)
24 Total-level control MASTER for the audio mix
(total of all signals);
the sum signal is sent via the jacks MASTER
OUT (13), TAPE OUT (15) and the USB jack
(C)* and can be monitored via the outputs
PHONES (11) and BOOTH OUT (12).
Operating elements for the effect processor*:
25 Selector switch FX SELECT to select an
effect (16 predefined effects available)
26 Level control for the effect signal:
– FX LEVEL for the selected effect 1 – 16
– REVERB LEVEL for the reverberation
effect
27 Overload indicator PEAK for the input of the
effect processor
2 Safety Notes
The units (mixer and power supply unit) corre-
spond to all relevant directives of the EU and are
therefore marked with
.
WARNING The power supply unit uses dan-
gerous mains voltage. Leave serv-
icing to skilled personnel. Inexpert
handling or modification may re -
sult in electric shock.
Please observe the following items in any case:
G
The units are suitable for indoor use only. Pro-
tect them against dripping water and splash
water, high air humidity and heat (admissible
ambient temperature range: 0 – 40 °C).
G
Do not place any vessel with liquid on the
units, e. g. a drinking glass.
G
The heat generated inside the mixer must be
dissipated by air circulation; never cover the
air vents of the housing.
G
Do not operate the mixer and immediately dis-
connect the power supply unit from the socket
1. if the mixer or the power supply unit is visi-
bly damaged,
2. if a defect might have occurred after the
mixer or the power supply unit was dropped
or suffered a similar accident,
3. if malfunctions occur.
In any case the units must be repaired by
skilled personnel.
G
For cleaning only use a dry, soft cloth; never
use water or chemicals.
G
No guarantee claims for the units and no lia-
bility for any resulting personal damage or
material damage will be accepted if the units
are used for other purposes than originally
intended, if they are not correctly connected
or operated, or if they are not repaired in an
expert way.
If the units are to be put out of operation
definitively, take them to a local recyc-
ling plant for a disposal which is not
harmful to the environment.
3 Applications
This audio mixer is designed for universal PA
and recording applications. It provides two mono
and two stereo input channels to connect micro-
phones (also phantom-powered) and audio
sources with line output levels (e. g. musical
instruments and reproduction units). A send way
allows for the use of an effect unit. In addition,
connections for a recorder are available. Audio
mixing may be monitored by means of head-
phones and/or a monitor system in a separate
control room.
The model MMX-22UFX additionally provides an
internal effect processor (16 predefined effects
and/or one reverberation effect may be selected)
and a USB audio interface for connection to a
computer.
* only for model MMX-22UFX
