 Features of the wireless transmitter and receiver  

• 2.4GHz is an ISM frequency band which is legal and free all over the world.

   

• Unlike UHF device’s analog signal, 2.4GHz can realize digital transmission.

   

• The sampling rate is 64K@16bit*2, we call it HDCD sound.

   

• Latency time: 1.1~2ms. It is the shortest latency time in this field.

   

• The practical test S/N ratio is 89dB, and the practical test THD is 1.5%.

   

• Support at most 6 sets using at the same time without mutual interference.  

   

• Multiple sets of receivers can be operated with a single transmitter within the operating range.

   

• The receiver has been adopted by APEC2014 for simultaneous interpretation and deploying staff.
