29. AUX/FX SEND

These rotary controls could also be defined as FX SEND master controls, since they
are used to adjust the overall level of the effect mix that you have established using
the channel FX send controls. The AUX/FX SEND controls are used to set the input
levels of the corresponding FX unit, respectively the levels of the AUX SEND outputs.
Whenever the Peak LED (PK) blinks, there is the potential risk that the FX input signal
is driven into clipping, making it necessary to reduce its level by turning the
corresponding AUX/FX SEND control to the left, until the LED is not lit anymore.
Since the AUX/FX SEND controls not only affect the signals of the FX buses but also
the monitor effect level, which is set by the FX to AUX3 control, careless changes
can result in acoustical feedback.

30. FX ON

These switches are used to turn the internal FX units on – the green LED is lit. Please
keep in mind that you also can use an external foot switch to turn the FX units on. In
this case the LED also shows the actual state of operation. If you want to use a foot
switch, the FX ON switch has to be engaged first. The corresponding FX unit is
activated and you can use the foot switch to turn the selected effect program on or
off.

31. PEAK LED

These indicators signal if the input stages of the internal FX units or the AUX 1/"
SEND signals are driven into clipping. To achieve an adequate S/N ratio, please
adjust the FX units’ input level as follows:
Note on how to adjust the FX input signal:
1.Establish a “dry” mix – without effect settings – according to the previous descrip-
tions.
2.Set the AUX/FX send controls of the effect channels to their center position.
3. Position the effect return faders of the effect channels at the –5dB marks.
4.Use the UP/DOWN buttons to select the desired FX program preset.
5.Press the FX ON switch.
6.Play the sound source of the desired input channel and adjust the desired
amount of the FX signal, using the AUX/FX controls of this input channel.
Repeat this step for all input channels that you want to include in your effect mix.
7.Adjust the AUX/FX SEND controls, so that the Peak LED only lights frequently
at highly dynamic signal peaks.
8. Use the FX to AUX3 control to add the effect mix to the monitor mix. Use the
FX return faders to add the desired amount of the FX signal to the main mix.
In case you are using a different effect setting for the second FX unit, you have to
repeat the step 2 - 8, respectively. Pay some attention to the peak indicators when
operating your PowerMate to quickly interact when the signal levels exceed the
normal range and enter clipping.

32. EFFECT RETURN

These stereo faders are used to determine the effect amount of the main mix. In case
you have to set these faders at a position above the +5dB mark, please check if the
FX units input signals are adjusted properly. Otherwise use the AUX/FX SEND
controls to increase the input levels.
