Essential Information About the Mipro ACT-343 4-Channel Wireless Receiver

  • True Diversity Reception for a more stable UHF connection and better resistance to dropouts in busy environments.
  • 4 channels in 1U : a compact 19-inch rack solution to manage multiple microphones/headsets/instruments on a single receiver.
  • SCAN, ACT, and SQUELCH functions : frequency scanning, quick synchronization, and background noise control for smooth use on stage or in installations.
  • Comprehensive outputs : 4 balanced XLR and 4 unbalanced 6.35mm Jack outputs, with adjustable levels to match your console, interface, or sound system.

A 4-channel receiver designed for multi-transmitter ACT configurations

The Mipro ACT-343 is a UHF multichannel receiver focused on efficiency: it centralizes up to four RF links in a standard 19-inch rack format (1U), convenient for mobile sound desks, stage setups, and fixed installations. Its "multi-frequency" logic and channel selection tools aim to simplify the deployment of multiple simultaneous systems, while maintaining clarity through the LCD display.

For stage, conference, and installation: who is the ACT-343 for?

This receiver is particularly suited for users who need to manage multiple transmitters in parallel (voice, presentations, theater, places of worship, schools, events, animation) without multiplying the number of units. In a rack, it integrates easily into a flight case or technical rack. Sound engineers will appreciate the presence of separate outputs per channel, while technical teams will save time thanks to the scan and synchronization functions.

Key features: RF stability, frequency selection, and professional connectivity

True Diversity: more robust reception

The ACT-343 is a True Diversity receiver, an architecture designed to improve transmission stability in UHF. With two reception paths and appropriate diversity management, the system helps limit losses related to multipath and signal variations, common on stage or in reverberant rooms.

SCAN, ACT, and SQUELCH: quick setup and noise control

The SCAN function facilitates searching for an available frequency within the band. The ACT function is designed to speed up pairing/synchronization with compatible transmitters, achieving a coherent link without endless adjustments. The SQUELCH allows adjustment of the threshold to better control unwanted noise when the signal becomes too weak or unstable.

Separate audio outputs: direct integration to your sound desk

Each channel has dedicated outputs, allowing precise routing of each microphone or source to a console, stagebox, or recorder. You benefit from balanced XLR outputs suitable for long cable runs in stage environments, as well as unbalanced 6.35mm Jack outputs convenient for certain configurations. The offered output levels help adapt to line inputs depending on the equipment used.

Detachable antennas and external antenna compatibility

The antennas are detachable and the TNC 50-ohm connector is designed for use with external antenna systems, useful when the receiver is in a closed rack, in a remote control room, or when you need to optimize RF coverage in a venue.
