EVO HANDHELD
DYNAMIC MICROPHONE
Using The Microphone On Vocals
Controlling Feedback (continued)
Feedback may also be triggered by room resonances (deter-
mined by the acoustics of the room you're in), particularly in
the low-frequency region (i.e., indirectly by the proximity
effect). In this case, you can easily stop the howling just by
moving a bit away from the microphone.
Background Vocals
Never let more than two people sing into one microphone.
With more singers, sound arrives at an angle greater than 35°
off-axis and is picked up in the region where the microphone
starts to becomes less sensitive. To attain the same loudness as a
solo voice, mixer gain would have to be boosted and feedback
risk would therefore increase.

Microphone Care
The EVO Handheld Dynamic Microphone has a matte
nickel-plated housing that is easily cleaned with a soft cloth,
slightly dampened in water. After extended use, a windscreen
will become soiled by dust and saliva and start to alter the
sound and feedback performance of any microphone. We
therefore recommend washing the foam windscreen with water
or a very mild detergent solution and letting it dry overnight.
