Product Description

The Mekey Advanced Wireless Microphone System (Mi-1604ha) pairs one transmitter with four receivers, delivering reliable multi-channel audio for conferences, presentations, and performance environments.

  • 1Distributed reception technology ensures a more stable signal, a longer reception distance, and broader applicability.
  • 2A 2U standard chassis with a color large-screen display presents the system menu clearly. Each channel's RF and audio status is independently shown via LED indicators for an intuitive overview.
  • 3Four channels offer independent volume adjustment, along with SQ and IR infrared frequency pairing control. A 4+2 audio output mode greatly simplifies daily operation.
  • 4Real-time monitoring of transmitter battery level is supported, and the system menu stores six sets of stacked machine frequencies for quick retrieval. Transmitters can be mixed and matched across meeting, handheld, or clip-on applications.
  • 5The system operates on 4 × 50 frequency points, with each channel offering 50 adjustable points. The default frequency range is 640–690 MHz.
