In case of interference:
- power off all transmitters and check whether the “RF/PEAK” LED is blinking and glows
green. This allows to identify a possible direct source of external interference
- power on a transmitter at a time and check that only the corresponding receiver gets
synced, verifying that the “RF/PEAK” LED glows green and is steadily on.
The same radiofrequency choice criteria also apply if using the EME-ONE system along with other
radio microphones
6. CAUTIONS
“LARSEN” effect
The Larsen effect (also known as audio feedback) is an annoying sound generated when there
are any microphones which are too close to each other and are oriented toward the audio
speakers emitting the sounds picked by the microphones themselves. To avoid the Larsen effect
(which may damage the loudspeakers), we recommend that you leave a certain distance between
the microphones and the audio speakers; also lower the microphone volume (if needed) and don't
aim them at the audio speakers.
Induction-related phenomena
To prevent induction-related phenomena from generating buzzes and noise which compromise
proper system operation avoid placing the transmitters and receivers near equipment inducing
strong magnetic fields (e.g. power transformers, power conductors and lines powering the
speakers)
Drop outs
There area areas in which proper signal reception is difficult. To avoid drop outs you need to
move the transmitter to a more appropriate location, avoid interposing any obstacles and, if
needed, reduce the distance between transmitter and receiver.
Place the transmitter as far away as possible from the source of the disturbance, to avoid external
noises or unwanted sounds.
Volume levels
This equipment can generate high-intensity sounds in earpieces. Please take this
into account and keep volume as low as possible.
Please also remember:
TOO HIGH VOLUME LEVELS MAY RESULT IN PERMANENT DAMAGES TO HEARING
The limiters built into the system are designed to be able to control sudden level fluctuations; they
are NOT designed to serve as long-term hearing protections.
Periodically have a specialised audiologist check your ears. Should you experience any irritation
or earwax formation, IMMEDIATELY STOP USING THE EQUIPMENT and have your ears
checked as soon as possible.
