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 speaker. 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 speaker as possible. This will help 
achieve isolation between the speaker and the microphone, and allow you 
to increase the output of the Expedition Express.

• 

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 overall level of the speaker.
