MiPRO ACT-74 Wideband UHF True Diversity Wireless Microphone System


Key Features:

  • EIA standard 1U rack-mountable metal chassis with excellent heat dissipation & RF shielding characteristics.
  • UHF PLL-synthesized wireless microphone technology for enhanced RF stability, lowered spurious emissions and increased frequency agility.
  • 400 preset channels with 1-set of user-defined group that saves up to 16 channels.
  • Industry’s first ACT syncs automatically and quickly a working channel.
  • Dual “PiloTone & NoiseLock” circuits minimize interference.
  • Industry’s only full-color VFD screen delivers a bright, clear viewing in day/night environments with automatic lit (Working) and dim (Standby) display during performance.
  • All controls are intuitive and easily setup via a single rotary knob.
  • Industry’s only RF interference warning indicator for properly adjusts the SQ level. Increase sensitivity to extend receiving range; decrease the sensitivity to reduce interference.
  • Single channel output or mixed output and switchable three levels for the best sound quality options.
  • High dynamic range and high fidelity characteristics for transparent audio performance.
  • Receiver provides bias voltage for MIPRO antenna systems to enhance reception range and signal stability.
  • MIPRO RCS.Net software allows real-time computer set up, control and monitoring.
  • Built-in 100~240V AC switching power supply ensures system safety and stability.
  • Designed and made in Taiwan.
