equalizer to your liking.
2. Use the Reverb Program selector to choose one of the ten built-in digital effects.
3. Press the EFFECTS switch down on the chan-
nel to which you want to add the digital effect.
4. Once you have selected the channel(s) for effects by using the channel
EFFECTS switch, raise the effects SEND main level control to apply the
amount of effect desired.

Avoiding Feedback

Feedback is the annoying howling and squealing that can heard when the microphone
picks up sound from the speaker. The sound is then re-amplified back through the
speaker again, creating a feedback loop. Follow these steps to minimize the likelihood
of feedback:
• Avoid pointing the microphone directly at the speakers. In general it is
recommended that the microphone be positioned behind the speaker enclosure.
This uses the directional characteristics of the speaker and microphone to your
advantage.
• Keep the microphone as far from the speakers as possible. This will help achieve
isolation between the speaker and the microphone, and allow you to increase the
output of the XP10000.
• Position the microphone as close to the sound source as possible. This will
enable the microphone to pick up more direct sound, and allow you to reduce the
microphone input gain control.
• Reduce the MASTER LEVEL of the XP1000 system.
