or turn back the GAIN control (4) of the
channel correspondingly (if required, it can
also be fully turned to “MIN” or “MAX”) .
For the channels CH 1 to CH 4, the channel
VU meters (6) serve as control meters: they
show the level ahead of the fader for the
respect ive channel .

7) Adjust the desired sound with the equalizers

of the channel: For channels CH 1 to CH 4,
the high range (HIGH), the midrange (MID),
and the bass range (LOW) can be boosted up
to max . 15 dB or substantially attenuated up
to max . 30 dB with the 3-way equalizer (5) .
For the microphone channels, the high and
bass ranges can be boosted or attenuated up
to max . 15 dB with the 2-way equalizer (7) .

If the controls are in mid-position, there

is no influence on the frequency response .

Note:

Sound adustments influence the levels .

Therefore, after a sound adjustment, check the
channel level by means of the stereo VU meter
and readjust it, if necessary .

8) Make the adjustments for the remaining

connected input channels in the same way
as described above .

5.2 Settings when using an effect unit

All input channels can individually be placed
on the effect send way (for this, also see chap-
ter 4 .3) . The effect send way is a pre-fader way .
Therefore, the position of the channel faders
(12) does not influence the extent of the effect .
1) To send a channel to the send way, press the

SEND button (10) of the channel (LED above
the button lights up) .

2) With the RETURN control (23), adjust the

level by which the signals coming from the
effect unit are mixed to the stereo master .

5.3 Mixing of the audio sources

1) To mix the connected audio sources, switch

off the crossover function . For this purpose,
set the C .F . ASSIGN switches (26 and 28)
to “X” .

2) Advance the master fader A (16) or B (18)

to a position that allows you to adjust the
mixing relation of the audio sources in an
optimum way .

3) Use the channel faders (12) to adjust the

volume relation of the audio sources . If a
channel is not used, its fader should be set
to minimum .

4) With the master faders, separately control

each master channel by means of the stereo
VU meter (22) . For this, switch the VU meter
with the button (17) to display the respect ive
master channel . Usually, an optimum level
control is obtained if the VU meter shows
values in the 0 dB range at high volume .
However, if the output level is too high or
too low for the following unit, set the master
signal accordingly to a lower or higher level .

In case of music with pulsating signal

peaks (e . g . techno), the LED BEAT (24) of
the respective master channel lights to the
rhythm of the music .

5.4 Crossfading between

two channels / cut function

1) With the two C .F . ASSIGN switches, two

channels of the stereo input channels CH 1
to CH 4 are se lected for crossfading:
With the left C .F . ASSIGN A switch (26),
select the channel to be faded in if the cross-
fader (27) is moved to the left .
With the right C .F . ASSIGN B switch (28)
select the channel to be faded in if the cross-
fader is moved to the right .

2) Set the faders (12) of the channels not used

to minimum . Obtain the optimum level con-
trol for the two selected channels by means
of their faders (see chapter 5 .1) .

3) Crossfading between the two selected chan-

nels is now possible with the crossfader .

4) To produce special sound effects, for each of

the two channels certain frequency ranges
can be suppressed with the CUT buttons
(25): HIGH button for the high range, MID
button for the midrange, LOW button for
the bass range . With the button pressed,
(LED above the button lights up), the respec-
tive frequency band is attenuated to such
an extent that it can hardly be noticed in
the sound . To switch off the cut function,
release the corresponding button again .

5) Obtain the optimum level control for the

two master channels . For this purpose, see
chapter 5 .3, item 4 .

5.5 Talkover function for

the DJ microphone

The talkover function increases the audibility of
announcements via the DJ microphone during
the music program . To activate the function,
press the AUTO TALK button (8): if the button
is pressed (LED above the button lights up), the
levels of channels CH 1 to CH 4 are automati-
cally attenuated by 12 dB in case of announce-
ments via the DJ microphone [connected to the
XLR jack (1) or the 6 .3 mm jack (41)] . To switch
off the function, release the button again .

5.6 Pre-fader listening (PFL)

via headphones

Via the pre-fader function, it is possible to
monitor the microphone channel MIC 2 and
the stereo input channels CH 1 to CH 4 via
headphones connected to the jack (19), even
if the corresponding channel fader (12) is set to
minimum . Thus, e . g . on a CD, the de sired title
can be selected or the right moment for fading
in an audio source can be timed .

Alternatively, it is also possible to monitor

the current music program ahead of the master
faders (16 and 18) .
1) To monitor an input channel ahead of the

channel fader, press the PFL button (11) of
the channel . Turn the MIX control (21) to the
left stop (position “PFL”) .

To monitor the current music program

ahead of the master faders, turn the MIX
control to the right stop (position “PROG .”) .

2) Adjust the desired headphone volume with

the LEVEL control (20) .

5.7 Monitoring of the music program

via a monitor system

The music program currently playing can be
monitored ahead of the master faders (16
and 18) via a monitor system connected to
the BOOTH jacks (35) . Adjust the level for the
monitor system with the BOOTH control (15) .

5.8 Remote-controlling of turntables

and CD players

Turntables and CD players with contact control
connected to the channels CH 1 to CH 4 can
remotely be started via the mixer (fader start) .

If the unit is connected via a remote start

control line to the mixer (for this see chap-
ter 4 .4), a switch is closed when the respective
fader (12) is advanced and thus starts the turn-
table or CD player . If the fader is set back to
minimum, the switch opens and the connected
unit stops or switches to pause .
