4.2 Effect unit

GB
Via the send way AUX 2 that also serves as the
effect way for the internal effect processor, sig-
nal parts can be decoupled from the input chan-
nels, processed by means of an effect unit (e. g.
reverb unit) and returned to the mixer via the
Return inputs. The signal for this send way is
picked up post-fader, i. e. the channel signal is
added to the send way after the fader (1). Thus,
the effect part of a channel is always in propor-
tion to the channel level adjusted.
1) Use a 6.3 mm jack to connect the input of the
effect unit to the mono output FX SEND (26).
2) Return the signal coming from the effect unit
to the input AUX RET (25).
Note: When connecting a mono unit, only use the
jack L (MONO). The signal will then be internally
sent to the right and left channels.
3) Alternatively, feed the signals coming from
the effect unit to the line input of an unused
input channel.
For adding the signal to monitor way AUX 1,
an unused input channel must be available,
because this addition can only be carried out
with the control AUX 1 MON (8).

4.3 Recorder

A recorder can be connected to the jacks TAPE
IN and TAPE OUT (18) [L= left channel, R = right
channel]:
1) For recording, connect the input of the re -
corder to the RCA jacks TAPE OUT. At these
jacks, the sum signal adjusted by means of
the fader MAIN MIX (36) is available.
2) For replay, connect the output of the recorder
to the RCA jacks or to the 3.5 mm jack TAPE
IN. To add the signal of the jacks TAPE IN to
the sum signal, use the fader of the channel
CH 13-14 (1).

4.4 Headphones

The following signals can be monitored via head-
phones:
– the signals of the individual input channels
– the sum signal
– the signal of the send way AUX 1
– the input signal of the jacks AUX RET (25)
Connect the headphones (minimum impedance:
8 Ω) to the jack PHONES (19).

4.5 Monitor system for the musicians

When a monitor system is used for stage PA ap -
plications, the send way AUX 1 can be used as
a monitor way. The signal for send way AUX 1 is
picked up pre-fader, i. e. the channel signal is
added to the send way ahead of the fader (1).
Thus, the stage monitors provide the musicians
with an audio signal that has been separately
mixed.
Connect the amplifier of the monitor system
or an active monitor speaker system to the jack
MONITOR OUT (33). Alternatively, for mono-
phonic PA applications in halls via another chan-
nel, use a channel of the internal power amplifier
to amplify the monitor signal: Set the switch
AMPLIFIER ASSIGN (17) to mid-position.
Please refer to chapter 4.7 for information on
how to connect the speaker systems.

4.6 Additional amplifier

The internal power amplifier can be used to pro-
duce the sound for the audience. If the internal
power amplifier does not suffice or if the sum sig-
nal shall be audible in an additional room, con-
nect an additional amplifier to the output MAIN
OUT (45). At this output, the sum signal adjusted
by means of the fader MAIN MIX (36) is avail-
able. The RCA jacks TAPE OUT (18) can be
used as an alternative or in addition.

4.7 Speaker systems

For connecting the speaker systems, the
speaker jacks (49) or the SPEAKON
ble jacks (50) are available. If the SPEAKON
compatible jacks are used, insert the appropriate
speaker plug into the jack and then turn the plug
clockwise until it engages. To remove the
speaker plug, retract the latch of the plug and
turn the plug counterclockwise.
The correct connection of the speaker sys-
tems depends on the desired operation mode for
the power amplifier. This mode is adjusted by
means of the switch AMPLIFIER ASSIGN (17):
Stereo operation (switch in upper position)
The power amplifier amplifies the stereo sum
signal. Connect the speaker systems (minimum
impedance: 4 Ω) to the jack A (left channel) and
to the jack B (right channel).
2-channel operation (switch in mid-position)
In the channel A, the power amplifier amplifies
the mono sum signal; in the channel B, it ampli-
fies the signal of the send way AUX 1 for on-
stage monitoring by the musicians. Connect the
speaker system (minimum impedance: 4 Ω) for
the audience to the jack A, and connect the
speaker system (minimum impedance: 4 Ω) for
on-stage monitoring to the jack B.
Bridged operation (switch in lower position)
The power amplifier amplifies the mono sum sig-
nal to twice its power. The speaker (minimum
impedance: 8 Ω) or a speaker system group
with a total impedance of 8 Ω can only be con-
nected to the SPEAKON ® compatible jack A
in the following way:
Contact 1+ for the positive pole
Contact 2+ for the negative pole
2+ = 1-
2- 1+ =

Connection for bridged operation

4.8 Console light

To illuminate the mixer, connect a gooseneck
light (12 V /500 mA max.), e. g. model GNL-304,
GNL-305 or GNL-314 from "img Stage Line", to
the XLR jack LAMP (34). The light is switched on
and off together with the mixer.

4.9 Foot pedal for the effect processor

To be able to switch on / off the internal effect
processor from the stage, for example, connect
a foot pedal (e. g. FS-60 from MONACOR) to the
2-pole 6.3 mm jack FOOT SWITCH (27).

4.10 Power supply

Use the mains cable supplied to connect the
mains jack (46) of the mixer to a socket (230 V~/
50 Hz).

5 Operation

CAUTION Never adjust the speaker systems
and 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 any more after some
time. Therefore, do not further
increase a high volume after get-
ting used to it.

5.1 Switching on and off

®
1) To prevent switching noise and an excessive
volume, close the faders MONITOR (35) and
MAIN MIX (36) and set the control PHONES
(15) to minimum prior to setting the mixer into
operation.
2) Depending on the microphone type con-
nected, switch the 48 V phantom power sup-
ply on or off, using the switches PHANTOM
(14) [ chapter 4.1.1].
3) If the internal power amplifier is used, check
whether the switch AMPLIFIER ASSIGN
(17) has been set to the correct position
( chapter 4.7) and then switch on the
power amplifier, using the switch POWER
AMP (16). If the power amplifier is not used,
switch it off.
4) To switch the mixer on and off, use the
POWER switch (48). When the mixer is
switched on, the LED POWER (44) and the
display (24) light up.

5.2 Mixing input signals

The following steps merely serve as an aid; other
procedures are possible.
1) First, make the following basic adjustments.
a) Disengage all buttons PAD (10).
b) Set all equalizer controls HIGH, MID,
LOW (9) and all sliders of the equalizers
(31, 32) to mid-position.
c) Set all controls AUX 1 MON (8) and AUX 2
FX (7) for the send ways to minimum.
d) Set all panorama controls PAN (5) and all
balance controls BAL (6) to mid-position.
e) Set the control FX TO MON (22) to mini-
mum.
f) Disengage all buttons MUTE (4), PFL (3),
AFL (29, 37) and the buttons COMP/LIM
(38) and PFL/AFL – MAIN (42).
g) Close all channels faders (1) and the
faders FX TO MAIN (20) and AUX RET
(28).
2) Feed a signal to the channel that is to be
heard at the highest volume (e. g. sing into a
microphone, play a musical instrument) and
then advance the corresponding fader (1)
approximately to the position 0 dB.
The channel has been adjusted in an opti-
mum way when the LED PEAK (2) briefly
lights up for signal peaks. If it lights up for a
longer period of time, the channel is over-
loaded: Press the button PAD (10) to attenu-
ate the input signal or reduce the output level
of the signal source.
3) Advance the fader MAIN MIX (36) until the
subsequent adjustments can be heard well
via the speaker systems connected or via the
