ENGLISH
In case of interference, turn the 2 transmitters off and make sure that the
relevant receivers are in the ‘mute’ condition.
This procedure allows you to identify a possible direct external interference
source.
Turn on only 1 transmitter at a time, move it around to check the worst condition
and identify which is the receiver exiting from the ‘mute’ condition.
If a receiver not tuned to the frequency of the used transmitter exits from
the ‘mute’ condition, there is an inter-modulation problem and, therefore, it is
necessary to increase the distance between the transmitter and that receiver
(or find a better position).
ELECTROMAGNETIC FIELDS
To avoid the system is disturbed by hum / noise due to any inductive
phenomena, do not put the receiver near any equipment producing a
significant electromagnetic field (e.g. power transformers, electrical cable,
loudspeaker lines, etc.).
‘LARSEN’ EFFECT (AUDIO FEEDBACK)
The ‘Larsen’ effect (also known as audio feedback) is an unwanted sound
loop that occurs when live microphones are too close to (and pointed at)
loudspeakers emitting the same sounds captured by microphones. To avoid
the ‘Larsen’ effect (that may damage loudspeakers), keep a minimum distance
between microphones and loudspeakers, if necessary turn the microphone
volume down. Never point microphones at loudspeakers.
SIGNAL DROPOUTS
In certain areas it might be difficult (for the receiver) to receive the signal
correctly. Should signal dropouts occur, it may be necessary to move the
receiver to a most suitable position, to remove any obstacle and reduce the
distance between transmitter and receiver.
USE LICENCES
RCF transmitters fully meet all regulations in force.
Yet, in some countries, the use of radio systems must be approved by
local authorities and it may be necessary to get a licence (for legal use).
Your local distributor will provide you all necessary information.
