To add the input signals to the sum signal,
use the faders AUX RTN 1 and 2 (19).
Note: When connecting a mono unit, only use the
jack LEFT (MONO). The signal will then be inter-
nally sent to the right and left channels.
29 Input jacks and output jacks (RCA) for a
recorder; a 3.5 mm jack is also provided as
an input
The sum signal after the fader MAIN MIX (39)
is available at the jacks TAPE OUT.
To add the signal of the jacks AUX IN / TAPE
IN to the sum signal, use the control
2-TRACK IN (34).

ates in bridged mode (double output power
at an 8 Ω speaker) and amplifies the mono
sum signal.

stereo sum signal when it is sent to the power
amplifier [assignment switch (37) in the posi-
tion MAIN L / MAIN R]
40 Button COMP/ LIM (with LED indicator) to
switch on the compressor for the stereo sum
signal

the output PHONES / CTRL-ROOM (51)
43 Button AFL / PFL – MAIN (with LED indicator)
to select the signal that is to be indicated by
the level indicators (45) and to be sent to the
output PHONES / CTRL-ROOM (51)
Button disengaged:
The stereo sum signal after the fader MAIN
MIX (39) will be indicated and sent to the
output PHONES / CTRL-ROOM.
Button pressed:
The signal of a channel whose button PFL
(3, 21) or AFL (31, 44) is pressed will be
indicated and sent to the output PHONES /
CTRL-ROOM.
44 Button AFL (with LED indicator) to monitor
the signal of the jacks AUX IN / TAPE IN (29)
after the control 2-TRACK IN (34) via head-
phones or a monitor system connected to the
jack PHONES / CTRL-ROOM (51). To have
the level indicators (45) indicate the signal,
make sure that the button (43) beneath the
indicators is pressed.
45 Level indicators; indicate the level of the sig-
nal that has been selected to be monitored by
means of the output PHONES / CTRL-ROOM
(51), see item 43
46 Button MUTE (with LED indicator) to mute
the signal at the input AUX IN / TAPE IN (29)

3 Applications

This audio mixer with integrated stereo power
amplifier (class D, 2 × 400 W
ers) is suited for various PA and recording appli-
cations. It is designed as a table-top unit and
provides 12 mono input channels and 2 stereo
input channels for connecting microphones (also
phantom-powered) and audio sources with line
output level (e. g. instruments, players).
The input signals can be added to a stereo
sum channel, a mono sum channel and four
send ways. Two digital effect processors are
available for adding effects. Headphones or a
monitor system may be connected for monitor-
ing the audio mix or for pre-fader listening to indi-
compatible)
