Mipro ACT-74

The Mipro ACT-74 quad channel UHF radio mic receiver operates on channel 38. Licence required.

There are 400 preset channels on the ACT74 with a user defined group to save up to 16 channels.

48 compatible channels for maximum flexibility.

The colour VFD screen offers comprehensive system status information including: group, channel, frequency, name, RF & audio signal strength, diversity condition, transmitter battery level, squelch level and indication of interference.

True diversity operation ensures a long transmission range and freedom of movement and the Automatic Channel Targetting (ACT) feature makes system set up extremely simple by matching and synchronising transmitters and receiver at the press of a button.

The ACT-7 series receivers also have an advanced computer network-interfaced control feature which enables the system to be set up, controlled and monitored by PC using an optional Mipro hardware device via RS-232 or USB.

  • EIA standard 1U rack-mountable metal chassis with excellent heat dissipation & RF shielding characteristics.
  • UHF PLL-synthesized 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-colour 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.
