In 2006, MIPRO introduced the industry-leading ACT-8 digital wireless microphone system. It features excellent sound quality almost as good as the cable transmission. Moreover, the handheld microphone transmitter is fitted with latest interchangeable true condenser (TCM) and dynamic microphone capsules for unsurpassed audio quality and highly recommended by audio professionals.

Due to recent changes of telecom regulations in Europe and US, MIPRO introduced a new wideband digital receiver: ACT-82a. The bandwidth increased from 24 MHz to 120 MHz to adhere regulations in various countries. ACT-82a can work with the transmitters powered by AA battery like ACT-80H and ACT-80T, or the transmitters powered by rechargeable lithium battery like ACT-8Ha and ACT-8Ta.

  • Specifications
  • Transmitters
  • Accessories
  • The receiver is an EIA standard 1U rack-mountable metal chassis and the control panel, equipped with full-color VFD, is intuitive and easily accessible, allowing for quick and easy system setup via a single rotary control.
  • MIPRO’s latest IF filter circuitry improves RF dynamic range and anti-interference characteristics, increasing interference-free channels. Upgraded 120 MHz wide bandwidth allows more interference-free channels to be selected. Specific auto-tracking filter for the minimum pass-band loss and maximum anti-interference.
  • New digital diversity receiving technology eliminates signal dropout and enhances receiving range and increase stability.
  • Full-Range sound quality won’t be changed by the strength of RF signals or operation distance.
  • Digitally-processed RF circuitry and DigitnamicPlus™ technology eliminates compander noise assuring the wireless sound quality almost as good as cable transmission.
  • Improved < 2.9ms latency. Proprietary Audio A/D Converter provides a true dynamic range >115 dBA, T.H.D. < 0.04% at 1 kHz.
  • The AES/EBU Digital Audio Interface facilitates a direct connection to digital mixing consoles and transmits signal without distortion, therefore S/N ratio will not deteriorate in long distance transmission.
  • Proprietary 128-bit encryption guarantees secure audio transmission, preventing unauthorized listening.
  • Built-in 10 SmartEQ™ preset and user-defined microphone capsule equalization for faithful reproduction to suit artists’ preferences.
  • Wordclock in/out facility with activity indicator ensures correct synchronization with other digital equipment.
  • Optional MIPRO RCS2.Net software allows real-time network remote-controlling and monitoring of 64 systems.
