Revolabs HD single and dual channel microphone systems

The Revolabs HD single and dual channel microphone systems are high performance, professional wireless systems designed for use in a variety of venues ranging from small conference rooms to large auditoriums, to conference centres. Both the HD single and dual systems include everything necessary to add wireless, multi-channel microphone audio to almost any video and audio conferencing.


 Great Sound Quality for Almost All Applications

Revolabs HD single and dual channel microphone systems have high definition audio and are designed for speech. The system utilises 1.9 GHz DECT technology and high band-width audio from multiple wireless microphones, enabling clear, reliable, un-tethered communications in recording, audio and video conferencing, speech recognition, VOIP communications, sound re-enforcement as well as many other environments requiring clear audio capture.


The Revolabs HD™ Single and Dual Channel Wireless Microphone Systems have high definition audio, 50 Hz to 20 kHz, which allows the systems to pick up the entire human voice spectrum. The HD Single and Dual Channel Systems are a unique marriage of innovative technology and ergonomic design, employing Multi-Carrier Time Division Multiple Access and Time Division Duplex (MC/TDMA/TDD) radio transmissions both to and from the microphone. This technology allows the microphones to co-exist with other wireless products such as wireless LANs (802.11b&g), and includes digital encryption technology to ensure secure communications.


Depending on which system you decide on, your Revolabs HD™ System contains the following:

  • Mountable Single or Dual Channel Base Station
  • Single or Dual Channel Microphone Charger Base
  • HD Wireless Microphones, purchased and boxed separately

The Base Station houses the processor and one end of the wireless connection. It features one set of PCB diversity antennae and offers individual line-level or mic-level audio in/out for each microphone channel. This allows for external audio processing such as:

  • Mixing
  • Acoustic echo cancellation (AEC)
  • Feedback elimination
  • Level control
  • Equalization
  • Noise cancellation

The system is designed to optimize audio capture/reproduction by providing: Consistent audio input from all participants

  • Minimum room noise
  • Mute control
  • Wireless encryption
  • Automatic channel selection
  • Full duplex audio

The Charger Base charges the HD Wireless Microphones and stores them when not in use.
