INPUT MONO
Adjustments in the MID frequency range are certainly the most effective way to shape the
sound. As a matter of fact, determining the correct center frequency is not always as easy as
it seems. Here is one method – amongst others – how to quickly nd the right setting of the
parametric EQ for your application:
Setting Instructions:
1. Slightly lower the channel fader to avoid feedback.
2. Turn the MID rotary control all the way to the right (+15dB).
3. Play the desired sound source or talk into the microphone.
4. While doing so turn the frequency rotary control (kHz) slowly from left to right.
5. Surely and within no time, you will detect the frequency range that is not to your liking or
causing the feedback.
6. Leave the frequency control in this position and turn the MID control to the left until the
sound is natural or to your liking.
8. AUX / FX 1/2
The AUX/FX controls allow adjusting individual amounts of the input signals to be routed to the
integrated FX1 or the FX2 effects units. The signal path is split post volume fader – POST FADER
– so that the fader setting also inuences the amount of the signal that is fed to the FX units.
Using the AUX/FX controls lets you easily assign an effect for groups of musical instruments or
vocals. For example, you can assign a short reverb effect of the FX1 unit to the lead vocals and
a combined effects program – echo, hall, and chorus – via FX2 to the background vocals. To
determine the desired intensity of each effect, you should start with the controls set at their center
and make individual adjustments from there on. Please monitor the PEAK LEDs in the FX1/2
channels. The indicator should only light briey at the occurrence of high program peaks. If the
indicator is constantly lit, you should lower the send levels of those channels where the program
peaks occur. For further information, please read the paragraphs about the FX1/2 units.
(In case you are not using the internal FX units and/or you want to connect external signal
processing units, the pre-mixed AUX/FX1/2 signals are outputted via the AUX1/2 send jacks.)
9. AUX 3/4
AUX 3 and AUX 4 controls are primarily meant for establishing two independent monitor mixes.
Using the master section’s AUX PRE/POST switches allows determining whether the signals
are split pre or post fader.
PRE-FADER: The audio signal that is present at the AUX control is tapped pre volume fader
and therefore not affected by the fader’s setting. This mode is mainly used for monitoring. Pre-
Fader Monitoring is especially preferable when monitoring and main mix need to be completely
different from each other, e.g. when the volume setting of particular musical instruments or
vocals needs to be higher or lower than in the main mix. In most cases the mixing console is
placed somewhere in the audience area (FOH) and is being operated by an experienced sound
technician.
POST-FADER: The audio signal that is present at the AUX control is tapped post volume fader
and therefore affected by the fader’s setting. This mode is mainly used for establishing FX- or
special monitoring mixes. Using the POST-Fader method is recommended when the mixer is
also located on the stage and you have to operate it yourself.
