5.1.1 Phantom power

For microphones or other signal sources requiring phantom power,
a separate 48 V phantom power can be activated for each XLR con-
nection of the input jacks MIC 1– 12 (15)�
CAUTION Phantom power may damage signal sources with un-
balanced signal outputs� Never apply phantom power
to any inputs to which units with unbalanced output
are connected via XLR plugs�
When a microphone is connected or disconnected while the phantom
power is switched on, signal peaks will occur that, when amplified
and sent to the outputs, may damage the speakers or your hearing�
Therefore, first mute the corresponding channel with the key M (12)
☞
( chapter 5�2�3) and use the control H�P (4) to turn back the head-
phone volume (to the left stop)� If a monitor system is connected to
the MONITOR output (23), also turn back the volume of the monitor
system temporarily�
1) Select the channel and call up the view for matching the input

level ( chapter 5�1)�
2) Tap the button "48 V" on the screen� At the top of the channel
strip, "48 V" in red will indicate activation of phantom power�
3) To switch off, tap the button once again�

5.1.2 Signal inversion

The polarity of the signal can be inverted (phase reversal) if required�
This is useful when, for example, an audio source is picked up with
two microphones facing opposite directions (e� g� a drum where sound
is picked up from above and below)� In this case, one of the two
microphone signals should be inverted to avoid phase cancellation
while the two signals are being mixed�
1) Select the channel and call up the view for matching the input

level ( chapter 5�1)�
2) To activate the signal inversion, tap the button "REV" on the screen;
it will be displayed in colour� At the top of the channel strip, "REV"in
green will indicate activation of the signal inversion�
3) To deactivate the signal inversion, tap the button once again�
Note: For the stereo inputs ST 1 and ST 2, "REV" will only invert the left
channel� This is useful when, for example, one side has been accidentally
connected with reverse polarity when connecting a plug� This function is
not available for the input channel USB (for replay of an audio file) and the
digital input S / PDIF�

5.1.3 Signal delay

A delay can be set for the mono input signals (but also for the mixed
signals of the signal buses and of the stereo sum channel)� This is
useful when, for example, a sound source is picked up with multiple
microphones placed at different distances to the sound source� In this
X
case, the signal of the microphone closer to the sound source can
be delayed in order to avoid phase cancellation due to the different
sound delay times while the two signals are being mixed�

level ( chapter 5�1)�
2) To activate the signal delay, tap the button "IN" underneath
"Delay" on the screen; it will be displayed in colour� At the top
of the channel strip, ⓣ will indicate activation of the signal delay�
3) To adjust the delay time, use the control "Delay" displayed on the
screen or the control knob ADJUST (6)�
Note: The unit of measurement (ms, ft, m) for all delay settings can be selected
in the setup menu (
4) To deactivate the delay, tap the button "IN" once again�

5.1.4 Monitoring the signal

To monitor the input signal of the channel selected via headphones
and / or for example, via a monitor system in the control room, use
the Solo function�
CAUTION Never adjust 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 after some time� Therefore, do not further
increase a high volume after getting used to it�
1) Press the key SOLO (11) for the corresponding channel� The signal
of the channel is switched to the Solo bus now� The key will be
illuminated and "SOLO" will be indicated in green at the bottom
of the channel strip�
2) Use the control H�P (4) to adjust the headphone volume�
Note: This setting will not affect the signal at the output MONITOR (23)�
3) To deactivate the Solo function for this channel, press the key
SOLO once again�
When the Solo function is selected for multiple channels, the head-
phones will reproduce the mixed signal of these channels� When the
Solo function is not selected for any channel, the stereo sum will be
automatically routed to the Solo bus�
5.1.4.1 PFL /AFL, monitor level
The setup menu allows you to define if the Solo signal is to be mon-
itored ahead of the fader or after the fader�
1) Press the key SETUP (5)� The setup menu will be displayed�
2) Tap the button "Monitor" on the left to call up the view for the
settings used to monitor the signals (fig� 5)�
3) Tap the button underneath "Solo" to switch between "PFL" (pre-
fader listening) and "AFL" (after-fader listening)�
4) To compensate a difference in volume, use "PFL Trim" to addition-
ally match the monitor level for PFL�
The bar graph on the right will indicate the level�
5) In the section "Monitor/ Phones", use "Level" to adjust the general
monitor volume and "Mute" to mute the Solo channel�
The bar graph on the right will indicate the level�
6) To exit the setup menu, press the key SETUP�
