Adjust the intensity level that should be picked up by the receiver through the rotating volume button (- / +), item 1, and
monitor the saturation level on the display, item 2. As the volume increases and the transmitter (stick) is used, intensity
peaks can be monitored. Adjust the volume so it does not constantly reach the level PEAK 100%, avoiding audio
saturation. Adjust the mixer or amplifier gain level to obtain the best audio quality.
A vocal microphone provides many ways of shaping the sound of your voice as it is heard over the sound
system. The following sections contain indications on how to use your microphone system for best results.
Microphone distance and proximity effect
Basically, your voice will sound bigger and mellower the closer you hold the microphone to your lips. Moving
away from the microphone will produce a more reverberant, more distant sound as the microphone will pick more of
You can use this effect to make your voice sound aggressive, neutral, sensual, simply by altering your
distance from the microphone. The proximity effect is a powerful increase in low frequency response that occurs when
a sound source is close to a sound source (less than 5 cm). It gives more "body" to your voice and an intimate, bass-
heavy sound.
Unwanted noise
To avoid unwanted noise, do not turn the button off when the receiver is on and connected to the desk, as,
depending on the system configuration, it may create high-intensity noise. Try to let the button turned off when not
using it during your presentation.
Angle of incidence
Speak to one side of the microphone. This provides a well-balanced, natural sound. If you sing or speak
directly into the microphone, it will not only pick up excessive breath noise but also overemphasize "s", "sh", "tch", "p",
and "t" sounds in a very unnatural way.
Feedback
Feedback occurs when part of the sound projected by the loudspeakers is picked up by a microphone,
amplified and fed back to the speakers. Above a certain volume (the feedback threshold) this process becomes a
vicious circle, making the sound system howl and screech. The only solution is to turn down the volume.
To maximize gain before feedback, place the system loudspeakers in front of the microphones (along the
side face of the stage). If you use monitor speakers, be sure never to point any microphone directly at the monitors or
at the system loudspeakers.
Feedback may also be triggered by resonances (due to the room acoustics), particularly in the low frequency
range, and thus indirectly by the proximity effect. In this case, it is often enough to move away from the microphone a
little to stop the feedback.
Backing vocals
1) Never let more than two people share a microphone.
2) Please note the sound angle of incidence should not be above 35°.
