Speaker Placement; Avoiding Feedback - Samson EXPEDITION EXPRESS+ El Manual Del Propietario

Speaker Placement

The Expedition Express+ provides three different
placement options for your specific situation.
For maximum sound coverage the Expedition
Express+ can be used with a standard 1 3/8" speaker
stand. The speaker should be raised above the heads
of the listening audience. Take care when placing the
speaker on a stand, to ensure that it is on a level,
steady surface and will not tip over.

Avoiding Feedback

Feedback is the annoying howling and squealing that can be 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.

When using the speaker on the floor, or when the speaker is
below the listener, the Expedition Express+ features a monitor
angle position to project the sound up, towards the audience.
For smaller settings, the speaker can be placed vertically on a
table or desk.
Take care when placing the Expedition Express+ in direct sunlight
for long periods of time, as this may discolor or damage the unit.
Do not place the speaker on wet surfaces, as it can cause
malfunction. If you notice condensation on the unit, dry the
speaker before using or storing.
