Description

ACT-311

  • EIA standard 1/2U metal receiver.
  • Receiver provides bias for booster where MIPRO antenna systems can be added for extended receiving range and stability.
  • Backlit LCD displays group, channel, frequency, RF level, antenna selection, AF level, battery level indicator, interference warning indicator, and panel lock indicator.
  • A lit green light indicates a working mode when receiver detects an incoming signal or buttons touched. Light dims automatically when 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.
  • High efficiency and low spurious PLL circuitry with Auto Scan functioin. Each receiver is presets with 11 groups, Groups 1~6, 7~10 have 8 &16 compatible channels respectively. Up to 8 channels in group 11 can be saved and recalled within 961 user-defined frequencies. A total of 112 preset channels per band.
  • World’s first ACT™ function provides precise and rapid frequency sync to the transmitters.
  • Advanced diversity technology for optimum reception range and reduces signal dropouts and the “PiloTone & NoiseLock” dual-squelch circuits prevent noise interference.
  • Adjustable ‘SQ’ for higher sensitivity to increase receiving distance and lower sensitivity to reduce interference.
  • Industry’s only RF interference warning indicator for ideal SQ level adjustment.
  • DC input socket accepts 12~15V power supply.
  • Matching ACT-30H handheld and ACT-30T bodypack transmitters.

ACT-30T

  • Miniature, compact design.
  • Top features mute switch, mini-XLR connector and antenna.
  • Backlit LCD displays various parameters and indicators.
  • Unique battery cover design provides easy access to operational controls and protects against accidental change of settings.
  • Connector for optional MJ-70 remote mute switch cable.
  • Low spurious PLL-synthesized technology enhances frequency stability and reliability.  One-touch ACT syncs the transmitter and receiver frequency automatically.
  • Selectable impedance for microphone or guitar/line inputs.
  • 4-pin mini XLR connector is compatible with all MIPRO lavalier, headworn microphones and instrument cable.
  • Highly efficient power consumption circuitry ensures long operating hours from 2 AA batteries.
  • Adjustable belt clip allows wearing transmitter in up or down position.

MU-23D

  • Compact ear-hook design for a secure, ultra comfortable fit.
  • Supplied in three ear-hook sizes for ideal fit.
  • Detachable boom can be worn on left or right & detached for replacement or servicing.
  • MU-23 features a 3mm omni-directional capsule.
  • Resistant to moisture, perspiration and salts.
  • Detachable or fixed microphone boom options.
  • Soft yet flexible thin boom bends 120° and holder can be rotated for an ideal fit.
  • Ideal for speech and vocal applications.
