5.6.2 External effect units
External effect units can be inserted into the
input channels via the jacks INSERT (13) or be
connected to the send ways AUX 1 – 4. For the
external effect units connected via the jacks
INSERT, no additional adjustments can be
made on the mixer; however, make sure that the
units are connected correctly and switched on
and that the correct adjustments have been
made. Otherwise, the signal way in the corre-
sponding input channel will be interrupted and it
will not be possible to monitor the channel signal
or to add it to the sum signal.
Make the following adjustments for each of
the units connected to the send ways AUX 1 – 4:
1) To make sure that the subsequent effect
adjustments are audible, first set the corre-
sponding output controls and input controls
approximately to mid-position:
according to the send way used
the corresponding control AUX 1, 2, 3 or 4
(33)
according to the input used
the fader AUX RTN 1 or 2 (19)
or
the fader (1) of the corresponding input
channel
2) Switch on the desired effect at the effect unit
and adjust the processed effect signal as the
output signal.
3) Depending on the send way used as the
effect way, use the control AUX 1, 2, 3 or 4 (7,
9) to add the channel signals to the effect
way. With these controls, the desired effect
intensity can be separately adjusted for each
channel.
Before the send ways 1 and 2 are used as
effect ways, set the switch PRE / POST (8) to
the position POST. Thus, the signal is picked
up after the fader (1) [as it is for the send
ways 3 and 4]; i. e. the effect part of a chan-
nel is always in proportion to the channel
level adjusted.
Notes
1. If the output of the effect unit is connected to the
line input of an input channel, set the correspon-
ding control AUX ... (7, 9) of the channel to mini-
mum; otherwise, there will be feedback: If, for
example, the send way 3 is used for the effect
unit, set the control AUX 3 to minimum!
2. The signals of the effect ways 3 and 4 are also
sent to the inputs of the internal effect processors
( chapter 5.6.1). Therefore, use the controls
FX ... TO MAIN (23) to separately adjust the
intensity of the internal effects as required or
mute the internal effects by means of the button
MUTE (25).
4) Use the controls AUX ... (33) to adjust the
level of the total signal of a send way so that
the effect unit is not overloaded.
5) Use the appropriate input control to add the
signal coming from the effect unit; with the
input control, the effect intensity for all chan-
nels can be jointly adjusted:
— If the effect unit is connected to the input
AUX RETURN 1 or 2 (28), use the fader
AUX RTN 1 or 2 (19) to add the effect sig-
nal to the sum signal.
— If the effect unit is connected to the line
input (14, 15) of an input channel, use the
appropriate channel fader (1) to add the
effect signal to the sum signal. Addition-
ally, the appropriate controls AUX 1 and/
or AUX 2 (9) can be used to add the effect
signal to the send ways 1 and / or 2 (e. g.
when these send ways are used as moni-
tor send ways).
6) To temporarily mute the effect signal, press
the button MUTE (4, 22) of the channel to
whose input the effect unit is connected.
5.7 Monitoring via headphones
or a control monitor system
For monitoring via headphones or a control mon-
itor system connected to the jack PHONES /
CTRL-ROOM (51), the following signals can be
selected:
1. The stereo sum signal post-fader, i. e. after
the fader MAIN MIX (39)
Disengage the button AFL / PFL – MAIN (43)
beneath the level indicators. The LED next to
the button must not light up.
2. The signals of the individual input chan-
nels pre-fader, i. e. ahead of the channel
fader (1), the button MUTE (4) and the control
PAN (5) or BAL (6)
Press the button PFL (3) of the desired chan-
nel. The LED next to the button lights up as
an indication. Additionally, press the button
AFL / PFL – MAIN (43) beneath the level indi-
cators. The LED next to the button lights up.
3. The mono sum signal post-fader, i. e. after
the fader MONO (30)
Press the button AFL (31) above the fader
MONO. Additionally, press the button AFL /
PFL – MAIN (43) beneath the level indicators.
4. The input signals of the jacks AUX RE -
TURN 1 and 2 (28) pre-fader, i. e. ahead of
the faders AUX RTN 1 and 2 (19)
Press the button PFL (21) above the fader
AUX RTN 1 or 2. Additionally, press the but-
ton AFL/PFL – MAIN (43) beneath the level
indicators.
5. The input signal of the jacks AUX IN /
TAPE IN (29) post-fader, i. e. after the control
2-TRACK IN (34)
Press the button AFL (44) beneath the con-
trol 2-TRACK IN (34). Additionally, press the
button AFL / PFL – MAIN (43) beneath the
level indicators. Turn the control 2-TRACK IN
to the right so that the signal is audible. If the
input signal is not to be added to the sum sig-
nal, press the button MUTE (46) beforehand.
Notes
1. The level indicators (45) always indicate the sig-
nal that has been selected for monitoring.
2. The button AFL / PFL – MAIN (43) beneath the
level indicators takes priority over the buttons
PFL (3, 21) and the buttons AFL (31, 44). When
the button AFL / PFL – MAIN is disengaged, the
stereo sum signal will be monitored and indi-
cated.
The buttons PFL and AFL, however, have the
same priority. If some of these buttons are
pressed at the same time and if the button AFL /
PFL – MAIN is pressed as well, the mixed signal
of the corresponding sources will be monitored
and indicated.
