Here are a couple examples of how to use the FX processor on the XENYX series of mixers:
1. The first example will be for the HALL PRESET 01. With this particular preset, pressing the TAP button will turn on, or off, the BRILLIANCE parameter. Now, if we press the PROGRAM/ PARAMETER knob this will bring up the REVERB TIME parameter. There should be a little blinking dot in the bottom right hand corner of the screen. When this dot is blinking, it means that you can turn the PROGRAM/ PARAMETER knob to adjust the REVERB TIME for this preset. Turning this knob to the left will decrease the REVERB TIME and turning this knob to the right will increase the REVERB TIME. After setting the desired REVERB TIME for the HALL REVERB preset, the blinking dot at the bottom right hand corner of the screen will blink 10 more times. Then the screen will go back to "home", displaying the selected preset number, which was 01.
2. Now, let's try using a different preset. Select preset 08, which will be a DELAY. The TAP button at this point will be used to "tap" out the speed of the delay that you would like to hear. So, if you tap the TAP button rapidly a few times, the delay will sound very short. Now, press the PROGRAM/ PARAMETER knob. This will bring up the NUMBER OF REPETITIONS parameter. The same blinking dot in the bottom right hand corner of the screen will been seen to show that you are currently in this particular parameter setting. Turning the knob to the left will decrease the number of repetitions, and turning the knob to the right will increase the number of repetitions. After setting the desired repetition time, wait for the dot to blink ten times and then you will be brought back to the "home" screen, showing the DELAY preset number, which was 08.
