VHF Tour Guide System

This wireless tour guide system applies the stable and reliable wireless technology to analyze the difference available frequencies and picks the most suitable one with least disturbance for transition of audio signal. It digitizes the audio signal to process and modulation before transmit. Receiver will scan the signal via identification verifying, read the transmitter frequency, process and signal and convert to the analog original sound. It is a economic yet power full system suitable for various of applications.

●  Stylish design and small in size
●  Digital, DSP technology and with radio function
●  Totally 44 sets can be used in the same place
●  RFID software, radio frequency identification to prevent interference
●  Unlimited receivers using at the same place
●  Standard grey, optional in Red and Blue color
