UHF Wireless Conference System

SU204

 

SU204 is four channel wireless microphone system consists of 4 sets independent UHF receiver module with 100 frequencies. It is designed for stage, conference room, school, church and many other applications. and made up of four wireless conference microphones and 1 set equipped with mixer function of the receiving host composition. Working in UHF band, high-frequency circuits: adopt PLL phase lock loop control oscillations, audio lock code identification technology.

 Audio circuits: using high-performance dynamic extension and intelligent mixing circuit! Provide the original sound signal real! In addition the machine is equipped with RS - 232 control interfaces for convenient control to central controller

Main Features:

• Operating frequency: 700-900MH
• CPU control with LCD display make operation 0easy and performance outstanding
• Adopt PLL combined technology, and the transmitter power is adjustable, they can be used several sets at the same time without interference.
• Multi-channel and high frequency, fully eliminate the interference signal
• With audio compressing-expanding technology, reduce the noises and increase the dynamic range
• The function restrains the howling, can effectively reduce the howling
• Receiver with multi-level high-frequency amplification, with high sensitivity
• Multi-level noise supervisory circuit, can the TONE-LOCKED system, so that it have a good anti-jamming features
• Excellent chips and quality components used to make this machine excellent sound quality
• 100 meters in the spacious place, 50 meters for the ideal using range
