ACT-312B/ACT-32H2 Dual-Channel Handheld Wireless System

ACT-312B/ACT-32H2 Dual-Channel Handheld Wireless System MIPRO is a leading manufacturer of truly innovative wireless microphone systems. MIPRO’s industry-leading technology, including AutoScan and patented ACT (Automatic Channel Targeting) channel sync setup, deliver the forward-thinking features that enable our customers to specify and install our systems with confidence. MIPRO’s ACT 3B-Series systems are built to handle tough conditions, deliver superb RF reliability and transparent audio performance in a wide variety of professional venues and applications.

The ACT 3B-Series wireless systems are single and dual channel UHF frequency agile diversity systems that are affordable without sacrificing features and performance. The ACT-312B/ACT-32H2 is a UHF frequency agile single channel half rack receiver with two ACT-32H handheld condenser wireless transmitters.

ACT-312B Receiver

  • Available on bands 5NC (542-566MHz) and 9NA (904-928MHz)
  • EIA standard 1/2U metal rack-mountable receiver
  • Stable PLL circuit. Auto Scan function allows quick search for an interference-free working channel from 112 preset channels under 10 groups. Up to 8 channels in group 11 can be saved and recalled within 961 user-defined frequencies
  • World’s first ACT™ function provides precise and rapid frequency sync to the transmitters.
  • Advanced diversity technology for optimum reception range reduces signal dropouts and the “PiloTone & NoiseLock” dual-squelch circuits prevent noise interference
  • Backlit LCD is lit in green indicates the receiver is in working mode when it detects an incoming signal or buttons are touched. The display dims automatically when the receiver is idle for about 10 seconds
  • Balanced XLR / unbalanced 1/4 " audio output jack, output level switch and DC input are on the rear panel. One mixed-output switch is available for dual-channel receivers
  • Industry’s only RF interference warning indicator for proper adjustments of the SQ level
  • Increase sensitivity to extend receiving range; decrease the sensitivity to reduce interference
  • Receiver provides bias for booster where MIPRO antenna systems can be added for extended receiving range and stability
  • DC input jack accepts 12~15V power supply

ACT-32H Transmitter

  • Robust, lightweight plastic housing
  • The unique multi-layered metal grille protects the capsule against impact, rolling and pop noise, ensuring clarity of sound
  • Premium condenser capsules exhibit high fidelity, wide dynamic range, fast transient responses, good feedback rejection, accurate sound image characteristics, transparent sound quality and withstand maximum SPL
  • Reversible end-cap allows power on/off switch being locked to avoid accidental power-off during performance
  • Impact-resistant battery compartment holds 2 AA batteries
  • Backlit LCD displays various parameters and status
  • Stable PLL circuits. Automatically synchronized with the receiver’s frequency by MIPRO’s patented ACT™ function
  • Patented “built-in” antenna design
  • Interchangeable colored rings for microphone channel identification on stage
  • High-efficiency circuitry design provides more than 16 hours of operation from 2 AA batteries (depending on the battery quality)
