Electro-Voice STEREO POWERED MIXER PSX2200 - Manual (Page 11)

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 show 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 descriptions.
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 PSX 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.
