Introduction
LEM L3000-SD is an efficient, high-quality wireless microphone system, with an user-friendly control set.
The use of the UHF band (780-960MHz) enables the majority of interference problems afflicting lower
bands to be overcome. Shorter waves are less susceptible to reflection, so tend to saturate the area
round the transmitter better. The UHF band is therefore more suited to critical situations (stages or clubs
with a lot of lights and amplifiers) where reflections can cause problems for VHF sound waves.
The transmitter/receiver connection frequency has been pre-set on our premises and it is showed:
- on the products package;
- on the rear panel of the receiver;
- on the battery space inside the hanheld microphone;
- on the back of the bodypack transmitter.
The L3000SD receiver has two antennas and it makes use of the SWITCHING DIVERSITY technology.
This technology enables greater reliability and coverage than single antenna systems. In real time, the
circuitry automatically selects the antenna receiving the best signal, reducing breakdown and interference
risks. Switching between the two antennas, controlled by an opto-coupler, is immediate and totally noise-
free.
The system L3000SD comprises a receiver and four types of transmitter.
