      • Model: ST-209

      Feature :

      1.2*3 marshalling frequency are built-in, one button to adjust. One same frequency range available two receivers use in the same time.

      2.Infrared ray synchronization function, one button to connect and lock frequency automatically.

      3.Volume of eight channels is independent to adjust. Provide 8+1 audio output, each audio volume is independently output.

      4.Provide multiple transmitters to choose, conference, handheld and collar microphones can be mixed to use.

      5.Backlit LCD display show working station of RF, AF, frequency and channels.

      6.Adopt same working frequency for eight channels, transmitters can interchange at any time, this greatly enhance operation flexibility.

      7.Adopt newest UHF wireless audio transmit chip module IC which has excellent RF and AF performance, provide professional sound experience to customers. Squelch control and digital pilot technology, when transmitter turn off, pilot control will make AF signal to be mute to avoid noise, receiver’s channels also will be mute, this effectively cut off interference signal.
