5.1.4 Signal delay
For each signal (all input signals as well as mixed signals of the sub-
groups, Aux ways, effect ways and of the sum channel MAIN), a delay
can be set� This is useful when, for example, an audio source is picked
up with multiple microphones that do not have the same distance to
the audio source� In this case, the signal of the microphone closer to
the audio source can be delayed in order to avoid phase cancellation
due to the different sound delay times while the two signals are
being mixed�
1) Use the key ASSIGN (22) to call up the screen view "Channel"
(fig� 16) (press the key twice, if required)� The button "Delay" will
appear on the left side:
Delay Time
0.0 ms

2) To activate the delay, tap the button; it will appear in colour�
3) Use the rotary knob PARAMETER ADJUST (18) to adjust the delay
time�
4) To deactivate the delay, tap the button again�
5.1.5 Monitoring a signal
Use the Solo function to monitor the input signal of the selected
channel via headphones or via a speaker in the control room�
CAUTION Never adjust a very high volume� Permanent high vol-
umes may damage your hearing! Your ear will get ac-
customed to high volumes which do not seem to be
that high after some time� Therefore, do not further
increase a high volume after getting used to it�
1) The key SOLO CLEAR (6) will light up when at least one channel
has been set to the Solo bus� In this case, press the key so that it
extinguishes� This will ensure that the Solo bus is not used unin-
tentionally� Otherwise, the signals of multiple channels set to the
Solo bus will be mixed�
2) Press the key SOLO (23)� The signal of the selected input channel
will be set to the Solo bus�
3) To monitor the signal ahead of the volume control of the channel,
make sure that the key PFL (17) = "Pre-Fader Listening" is illumi-
nated (press the key, if required)�
4) Depending on the jack used for the headphones or the monitoring
system connected, adjust the monitoring volume with the control
HP1, HP2 or CTRL ROOM (15)�
5) To indicate the level of the signal monitored via the Solo bus, press
the key SOLO METER (5) so that it is illuminated�
5.2 Linking mono channels
If, in addition to the two stereo channel pairs CH 17/18 and CH 19/20,
further inputs for stereo signals are required, link two adjacent mono
channels as a stereo channel: The channel with the lower, uneven
number will become the left channel; the channel with the higher,
even number will become the right channel�
1) Use the keys (8) to select one of the input channels to be linked�
Please note that the settings of this channel will be adopted by the
other channel (exceptions: input gain, phantom power)�
2) Press the key LINK (23) so that it is illuminated� The channels are
now linked as a stereo channel� Both channels are selected and
can only be set together�
Note: The channels cannot be linked when one of the channels is assigned
to a DCA group (
☞
chapter 5�8)� In this case, a corresponding message will
be displayed�
3) To unlink the channels, press, with the two channels selected, the
key LINK so that it extinguishes�
The above procedure can also be used to link two adjacent subgroups
or Aux ways�
5.3 Assigning a signal path
There are many ways to add input signals to one or multiple outputs�
The following chapters will describe some of these options�
5.3.1 Signal sum MAIN
The easiest way to define a signal path is to directly route the signal
of an input to the sum channel MAIN� The sum signal MAIN will then
be available at the XLR jacks and the 6�3 mm jacks MAIN OUT (37)
and also, as a digital stereo signal, on a computer connected via the
jack USB AUDIO (35)�
1) Select the desired input channel with the appropriate key (8) and
then press the assignment key MAIN (23) so that it is illuminated�
2) To define the position of the input signal in the stereo panorama,
press the key PAN (23) and then position the signal with the rotary
knob PARAMETER ADJUST (18)� In the view "Assign" (fig� 9), the
setting will be indicated as a large-scale graphic:
Left
Pan
Fig. 8 Stereo panorama
Note: To reset the panorama setting on the screen, tap the centre of the
bar (fig� 8) twice�
In the other views, a small graphic is displayed above the respective
channel faders�
For stereo channels and mono channels linked as stereo pairs, the
panorama setting will shift the stereo balance�
3) The level indicators (4) for the left (L) and right (R) channels indicate
the sum signal MAIN�
4) Use the key MAIN (7) to select the sum channel MAIN to be con-
figured�
5) If required, make the following adjustments and changes to the
sum channel MAIN:
– change the balance between the left channel and the right
channel with the key PAN (23) and the rotary knob PARAMETER
ADJUST (18)
– invert the signals (see chapter 5�1�3)
– define a signal delay (see chapter 5�1�4)
– process the dynamic range (see chapter 5�4)
– adjust the sound (see chapter 5�5)
6) As already described for an input channel (
sum channel MAIN can be monitored via the Solo bus� However,
the sum channel MAIN cannot be selected via the key SOLO: it is
automatically selected provided that no other channel has been
assigned to the Solo bus� The easiest way to do this is to press the
key SOLO CLEAR (6)�
5.3.2 Subgroups SUB 1– 4
It is possible to combine multiple inputs in a subgroup first; the mixed
signal of the subgroup can then be routed to the sum
or, via the outputs SUB OUT 1– 4 (29), used for other purposes (e� g� for
external effects)� Thus, it is, for example, possible to group chorus parts
or various instruments of a drum set and then process them together�
1) To assign an input channel to one or multiple subgroups, press, with
the input channel selected, the keys SUB 1– 4 (23) of the desired
groups so that the keys light up�
2) The sum signal of a subgroup will be indicated by the level indicator
(4) located above the corresponding key�
