FEEDBACK TROUBLESHOOTING
If you are having problems with feedback, you will have to try one or more of the following:
1)
Move the mic farther away from the speaker
2)
Turn the volume down on the amplified speaker
3)
Turn down the vocal compression - a 1:1 compression will result in less feedback.
4)
Use a directional microphone, such as the Radio Shack
boom mic model #33-3012
Rule of Thumb: The closer the mic and speaker are, the worse this feedback is. Even if you eliminate feedback in
this extreme case, the slightest movement of your head will cause a new feedback path. As the speaker and mic are
separated, you will have more “leeway” in your head movement before feedback ensues
.
You can also make sure you are using the default auto VOX timeout of 2.5 sec, and limit all your sentences/words to
2 seconds or under. This will allow the board to close the mic quickly after you are done speaking, squelching any
feedback.
TIP: If you are having problems with feedback howling after you are done talking, try blowing into the mic or
saying something else. Feedback typically reduces in volume when you are talking or making noise into the mic.
You can do this until the mic auto closes to reduce any feedback from occurring.
Remember, feedback is always there, it is just a matter of how much you can attenuate it. Feedback is also directly
proportional to volume, so the more you turn up your speaker, the more feedback you will experience. Our Vortex
voice amp is the only unit capable of tackling difficult feedback paths by using advanced algorithms.
**** To totally eliminate stray feedback with the PRO trooper amp, consider enabling PTT mode and using the
pushbutton to manually open and close the mic. This will allow you to close the mic right after you are done talking,
which prohibits feedback from even starting. ****
