31 Level control AUX RTN to add the signals at
the input AUX RTN (56) to the sum channels
MASTER [button MASTER SUB 1-2 (39) dis-
engaged] or to the subgroup channels [button
pressed]
32 Buttons BOOTH to select the signals that are
to be monitored via the headphone jack
PHONES (52) and the output BOOTH OUT
(53) and that are to be indicated by the level
indicators (38):
– button MASTER MIX for the output signals
of the sum channels MASTER
– button CD / USB / TAPE for the input signals
of the jacks TAPE IN (23) and of the USB
port (45)
– button SUB 1-2 for the signals of the sub-
groups 1 and 2
Notes
1. If multiple buttons are pressed, the mixed signal
of the corresponding sources will be monitored
and indicated.
2. The monitor signals selected by means of the
buttons SOLO (2, 29) will take priority: If a button
SOLO is pressed, the corresponding signals will
be monitored and indicated instead of the signals
that may have been selected by means of the
buttons BOOTH.
33 Volume control BOOTH / PHONES for the
headphone output PHONES (52) and the
output BOOTH OUT (53)
34 Faders for the sum channels
35 LED indicator PHANTOM 48V: lights up
when phantom power for the inputs MIC (22)
has been activated
36 LED POWER ON
37 Control RETURN TO AUX 1 to add the sig-
nals of the internal effect processor or the sig-
nals of the jacks FX RTN (57) to send way 1
38 Level indicators, indicate the level of the sig-
nal that has been selected to be monitored
via the headphone output PHONES (52) and
the output BOOTH OUT (53):
– the signals of the input channels / send
ways for which the button SOLO (2, 29)
has been pressed
– if none of the buttons SOLO has been
pressed, the monitoring signal that has
been selected by means of the button
BOOTH (32)
39 Assign button MASTER / SUB 1-2 to forward
the signals of the input AUX RTN (56) to the
sum channels MASTER (button disengaged)
or to the subgroup channels (button pressed)
40 Button PFL /AFL (with LED indicator beneath
the button):
button disengaged = PFL (pre-fader listening)
The input channels for which the button
SOLO (2) is pressed will be monitored
ahead of the control PAN (7) or BAL (8)
and the fader (1); the send ways for which
the button SOLO (29) is pressed will be
monitored ahead of the control AUX SEND
(28, 30).
button pressed = AFL (after-fader listening)
The input channels for which the button
SOLO is pressed will be monitored after
the control PAN or BAL and the fader; the
send ways for which the button SOLO is
pressed, will be monitored after the control
AUX SEND.
41 Button TAPE / USB TO MIX: When the button
is pressed, the input signals of the jacks
TAPE IN (23) and of the USB port (45) will be
sent to the sum channels MASTER.
42 Button MUTE to activate / deactivate a se -
lected effect
When the effect is deactivated, the LED
PEAK above the button will light perma-
nently. When the effect is activated, the LED
will only light up briefly in case the effect
processor is overloaded.
43 Knob FX SELECT to select an effect: Turn
the knob until the appropriate effect number
starts flashing on the display. Then briefly
press the knob to confirm your selection.
44 Display EFFECT to show the effect number
selected
45 USB port (type B) to connect a computer;
can simultaneously be used as an output
(digital output of the sum signal) and as an
input [feed-in of audio data] (full-duplex mode)

1.3 Rear panel

46 Mains jack for connection to a mains socket
(230 V~ / 50 Hz) via the mains cable supplied
47 Support for the mains fuse
Always replace a blown fuse by a fuse of the
same type.
48 POWER switch
49 Switch PHANTOM of the 48 V phantom power
supply for all microphone inputs MIC (22);
when the phantom power is activated, the
LED PHANTOM 48V (35) will light up
Please observe the warning notes with regard
to the phantom power in chapter 4.1.1.
50 Outputs MASTER for the sum signal, e. g. to
connect the amplifier for PA applications in
halls
– via XLR jacks,
Left L / Right R, balanced
– via 6.3 mm jacks
Left L / Right R, unbalanced
51 Connection FOOT SWITCH (6.3 mm jack,
2 poles) for a foot pedal to activate / deactivate
the internal effect processor
52 Output PHONES (6.3 mm jack) to connect
stereo headphones (minimum impedance:
8 Ω)
53 Output BOOTH OUT (6.3 mm jacks Left L/
Right R, unbal.) to connect a control monitor
system
54 Outputs SUB OUT (6.3 mm jacks, unbal.) for
subgroups 1 and 2
55 Outputs AUX SEND (6.3 mm jacks, unbal.)
for send ways 1 and 2
56 Inputs AUX RTN (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
Note: To connect a mono unit, only use the jack L.
The signal will then be internally sent to the right and
left channels.
57 Effect signal inputs FX RTN
(6.3 mm jacks Left L/ Right R, unbal.)
When the inputs are connected, the input sig-
nal is sent to the sum channels and the signal
way from the internal effect processor to the
sum channels is interrupted.
58 Jacks CHANNEL INSERTS (6.3 mm jacks) to
insert effect units (e. g. compressors) into the
mono input channels CH 1 to CH 8
Plug connections:
tip = Send (output)
ring = Return (input)
sleeve = Ground

3 Applications

This audio mixer is designed for various PA and
recording applications. It provides 8 mono and
2 stereo input channels to connect microphones
(also phantom-powered) and audio sources with
line output level (e. g. instruments and players).
The input signals can be added to a stereo sum
channel, two subgroups and two send ways.
The integrated effect processor can be used to
add effects. Audio mixing may be monitored by
means of headphones and / or a monitor system
in a separate control room.
In addition to the RCA jacks for a recorder,
the mixer provides a USB audio interface for
connection to a computer. This interface may be
used as an output for digital recording of the
audio mix and as an input for feeding in audio
files.
