Adjustments in the MID 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 find the right setting of the parametric EQ for your
application.
Note on how to adjust the parametric EQ:
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.Meanwhile 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 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.
It is a different story when you want to enhance a specific frequency range. In this case perform
steps 1 to 4 as described above. Set the frequency rotary control to the range you want to enhance
or leave it at the position where the sound is most satisfactory. Now you can use the MID control
to determine the amount of the alteration.
8. AUX/FX
The AUX/FX controls are used to adjust individual amounts of the channel signals to be routed to
the FX1 or the FX2 units. The split point of the “dry” signal is POST FADE or in other words: the
signal path is split after the audio signal has passed all stages of the channel module, including
the volume fader. That is the reason why the fader setting also influences the amount of the signal
that is fed to the FX units. Using the AUX/FX controls it is easy to establish an effect mix. For
instance, you can assign the short reverb effect of the FX1 unit to the lead vocals and a combined
effect 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. Also keep in mind that there are two AUX/FX1/2 send controls
located within the master section which control the total amount of the FX signals. When you begin
to establish the effect mix these controls should also be set at their center position.
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. Please monitor
the PEAK LEDs in the FX1/2 channels. The indicator should only light briefly 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.
9. AUX 3
The AUX 3 control is primarily meant for the monitor mix. Nevertheless, when the master section’s
AUX3 POST button is pressed, it can also be used as a third FX send bus. In that case the signal
is split post fader and outputted via the AUX 3 send jack.
To establish a monitor mix you can choose between two alternatives. The main difference of the
two options is the point where the signal gets split up; according to the setting of the AUX3 POST
button.
The AUX3 POST button is not engaged: the signal split lies PRE FADER – the setting of the
channel faders does not affect the signal level that is present at the AUX3 rotary controls. Since
the monitor mix is not influenced by the setting of the channel faders, this alternative is primarily
used when the main mix and the monitor mix have to be completely different – the volume of
specific musical instruments or vocals needs to be higher or lower or should not appear at all in
the monitor mix. This mode is also preferable when the PowerMate is operated by a technician in
the audience area (front ofhouse).
The other alternative should be used when you have to operate the mixer on-stage and still want
to have control over the main mix.
