The red “+48 V” LED lights up when the phantom power supply is switched
on. The phantom power supply is necessary for condenser microphones and is
activated using the corresponding switch on the rear of the device.
◊
Connect microphones before you switch on the phantom power supply.
Please do not connect microphones to the mixer (or the stagebox/
wallbox) while the phantom power supply is switched on. In addition,
the monitor/PA loudspeakers should be muted before you activate the
phantom power supply. After switching on, wait approx. one minute to
allow for system stabilization.

LEVEL SETTING:
When recording to a digital device, the recorder’s peak meter should not exceed
When recording to a digital device, the recorder’s peak meter should not exceed
0 dB. This is because, unlike analog recordings, slightly excessive levels can create
unpleasant digital distortion.
When recording to an analog device, the VU meters of the recording machine
When recording to an analog device, the VU meters of the recording machine
should reach approx. +3 dB with low-frequency signals (e.g. kick drum). Due to
their inertia VU meters tend to display too low a signal level at frequencies above
1 kHz. This is why, for example, a Hi-Hat should only be driven as far as -10 dB.
Snare drums should be driven to approx. 0 dB.
◊
The peak meters of your EURORACK display the level virtually
independent of frequency. A recording level of 0 dB is recommended
for all signal types.

The switch turns on the FBQ Feedback Detection System. It uses the LEDs in the
frequency band faders to indicate the critical frequencies. On a per-need basis,
lower the frequency range in question somewhat in order to avoid feedback.
The graphic stereo equalizer has to be turned on in order to use this function.

Logically, at least one (ideally several) microphone channels have to be
open for feedback to occur at all!
open for feedback to occur at all!
Feedback is particularly common when stage monitors (“wedges”)
are concerned, because monitors project sound in the direction of microphones.
Therefore, you can also use the FBQ Feedback Detection for monitors by placing
the equalizer in the monitor bus (see MAIN MIX/MONITOR).
