tion of stereo headphones (minimum imped-
ance 8 Ω)

fier of a monitor system in a separate control
room
17 Output TAPE OUT (RCA jacks Left L / Right R)
for connection of a recorder for recording
18 Input TAPE IN (RCA jacks Left L / Right R) for
connection of a recorder for reproduction or
another reproducer such as CD player
19 Button PHANTOM: with the button pressed a
48 V phantom power is activated for all inputs
MIC (1)
Please pay attention to the warning notes in
chapter 4.1.
20 Level control FX SEND for the signal of the
effect send way at the output FX SEND (13)
21 Button TAPE TO CTRL ROOM: with the but-
ton pressed the signal of the input TAPE IN
(18) is sent to the monitoring outputs
PHONES (14) and CTRL ROOM OUT (16)
and indicated via the level display (27)
Note: If the button FX TO CTRL R. (23) is addition-
ally pressed, instead of the TAPE IN signal the
effect way is monitored and indicated
22 Button TAPE TO MIX: with the button
pressed the signal of the input TAPE IN (18)
is sent to the master signal
23 Button FX TO CTRL R.: with the button
pressed, the signal of the effect way, ahead
of the output control FX SEND (20), is sent to
the monitoring outputs PHONES (14) and
CTRL ROOM OUT (16) and shown via the
level indication (27)
24 Volume control PHONES / CONTROL ROOM
for the monitoring outputs PHONES (14) and
CTRL ROOM OUT (16)
25 POWER LED

27 LED level indication; shows
a) the master signal,
when the buttons TAPE TO CTRL ROOM
(21) and FX TO CTRL R. (23) are not
pressed
b) the signal at the input TAPE IN (18),
when the button TAPE TO CTRL ROOM is
pressed and the button FX TO CTRL R. is
not pressed
c) the signal of the effect way ahead of the
output control FX SEND (20)
when the button FX TO CTRL R. is pressed

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 is supplied
with hazardous mains voltage.
Leave servicing to skilled person-
nel only. Inexpert handling or
modification of the unit may cause
an electric shock hazard.
It is essential to observe the following items:
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 vessels filled with liquid, e. g.
drinking glasses, on the units.
G
The heat being generated in the mixer must
be carried off by air circulation. Therefore, the
air vents at the housing must not be covered.
G
Do not set the mixer into operation, or imme-
diately disconnect the mains plug of the power
supply unit from the mains socket if
1. there is visible damage to the mixer, the
power supply unit or to the mains cable,
2. a defect might have occurred after a drop or
similar accident,
3. malfunctions occur.
The units must in any case be repaired by
skilled personnel.
G
A damaged mains cable at the power supply
unit must only be replaced by skilled person-
nel.
G
Never pull the mains cable to disconnect the
mains plug from the mains socket, always
seize the plug.
G
For cleaning only use a dry, soft cloth, never
use chemicals or water.
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 not repaired in an expert way.
G
Important for U. K. Customers!
The wires in this mains lead are coloured in
ac cordance with the following code:
blue = neutral
brown = live
As the colours of the wires in the mains lead of
this appliance may not correspond with the
coloured markings identifying the terminals in
your plug, proceed as follows:
1. The wire which is coloured blue must be
connected to the terminal which is marked
with the letter N or coloured black.
2. The wire which is coloured brown must be
connected to the terminal which is marked
with the letter L or coloured red.
If the units are to be put out of operation
definitively, take them to a local recy-
cling plant for a disposal which is not
harmful to the environment.
3 Applications
This mixer designed as a tabletop unit is suited
for sound mixing used for PA applications and
recording applications. The model MMX-1024 is
equipped with 6 input channels (2 mono, 4
stereo) and the model MMX-1244 is equipped
with eight input channels (4 mono, 4 stereo) for
connection of (phantom-powered) microphones
and audio sources with line output level such as
musical instruments, CD players. Via insert
jacks in the mono channels, units for sound pro-
cessing can be inserted. A send way (signal
pick-up "post-fader") allows for connection of an
effect unit. In addition, a reproducing input and a
recording output for a recorder are available and
monitoring outputs for connection of head-
phones and a monitor system in a separate con-
trol room.
4 Connection
Prior to connecting any units or to changing any
existing connections, switch off the mixer or set
the output controls PHONES / CONTROL ROOM
(24) and MAIN MIX (28) to minimum.
4.1 Microphones
Connect microphones via XLR or 6.3 mm plugs
to the balanced jacks MIC (1) of the mono chan-
nels. The XLR connection has a latching. To pull
