2) With the faders (5), adjust the volume for the
input channels CH 1 – CH 4 . The VU meter (11)
shows the signal level at the master output
AMP (19) . At 0 dB, the mixer is set to maximum
gain . In case of overload, the red LEDs of the
VU meter light up .
3) Adjust the desired tone for the two outputs
REC (18) and AMP (19) with the 3-way equal-
izer (10): the controls can be used to attenuate
or boost the LOW, MID and HIGH frequen-
cies by up to 10 dB . With the controls in mid-
position, there is no effect on the frequency
response .
4) The crossfader (6) is used to fade between two
of the channels CH 1 – CH 4 . To do so, select
the desired channels with the C .F . ASSIGN
switches A and B (7):
C .F . ASSIGN A: position 1, 2 or 3 to select
channel CH 1, CH 2 or CH 3
C .F . ASSIGN B: position 2, 3 or 4 to select
channel CH 2, CH 3 or CH 4
When the respective switch is in position 0,
no channel is selected .
When moving the crossfader to the left, the
channel selected with the C .F . ASSIGN A
switch is faded in and when moving the fader
to the right, the channel selected with the
C .F . ASSIGN B switch is faded in . When the
fader is in mid-position, both channels are sent
to the outputs at the same time . To decativate
the crossfading function, set both C .F . ASSIGN
switches to position 0 .
5.2 Monitoring the channels
With the monitoring function (PFL = Pre Fader
Listening), it is possible to monitor each individ-
ual input channel CH 1 – CH 4 and the MASTER
channel via headphones . The level of the signal
monitored is independent of the position of the
corresponding channel fader .
1) Connect stereo headphones (impedance ≥ 8 Ω)
to the jack (16) .
2) Press the corresponding PFL button (14) of
the channel .
3) Adjust the desired headphone volume with
the LEVEL control (15) .

5.3 Microphone announcements
1) Adjust the desired volume with the LEVEL con-
trols (3) for the microphone channels MIC 1
and MIC 2 .
2) Adjust the desired sound with the controls (2):
the low (BASS) and high (TREB) frequencies
can be attenuated or boosted by up to 10 dB .
3) To make it easier to understand a microphone
announcement, the levels of the channels
CH 1 – CH 4 can be attenuated by 15 dB . To
do so, set the talkover switch (8) to TALK po-
sition . In OFF position, the talkover function
is deactivated .
