* UHF band 740 – 865 MHz, PLL synthesized with 16 selectable channels.

* Built-in hidden condenser microphone offers alternative of headset microphone and lavalier microphone.

* Up to 8 frequencies used simultaneously, allowing the system to be applied for multi-language or simultaneous translation.

* Incorporated AUX input allows audio from a CD or MP3 player. Offering extra preferences of audio resource.

* DC input offers alternative power resource.

* Transmission range up to 80 meters (opening area).

* Rechargeable function design.
