Mipro ACT-311II Wireless Receiver

ACT-311II: A Receiver from the ACT Series Designed for On-Stage Reliability

The Mipro ACT-311II is part of the ACT range with a clear approach: to offer a reliable analog UHF receiver that is simple to deploy and flexible enough for live performances, events, houses of worship, or mobile installations. Its half-rack 19" (1/2U) format facilitates integration in flight cases, technical racks, or on shelves, while maintaining field-oriented ergonomics thanks to its backlit LCD screen.

With its multi-frequency management (groups and channels) and tuning assistance functions, it targets users who want to save time during setup while maintaining consistent reception quality in environments sometimes crowded with signals.

For Whom and For What: Voice, Presentation, Hosting, and Musical Applications

The ACT-311II is an excellent choice if you need a 1-channel wireless receiver for voice (singing, speech, conference, theater) or for musical applications requiring clear and natural reproduction. Its specified frequency response from 50 Hz to 18 kHz makes it suitable for RF systems intended for precise listening, especially when intelligibility is crucial.

It suits both technicians looking for a stable and quick-to-coordinate solution and users deploying a wireless system occasionally: Auto Scan helps find an available frequency, while Squelch limits signal opening when reception becomes insufficient.

Features and Highlights: RF Stability, Synchronization, and Control

True Diversity: Minimizing Dropouts and Stabilizing Reception

The True Diversity design is based on a simple principle: securing reception by exploiting diversity to reduce the effects of fading and reflections (common indoors and on stage). The result is more consistent behavior, particularly useful when the transmitter is moving.

ACT, Auto Scan, and Squelch: A Trio Designed for Field Use

The ACT-311II integrates functions that speed up preparation. Auto Scan helps identify an available frequency, ACT simplifies synchronization with compatible transmitters, and Squelch allows adjusting the threshold to avoid unwanted noise when the signal becomes too weak. This combination provides real operational comfort, especially when changing venues or needing to adapt quickly to a frequency plan.

PiloTone and NoiseLocke: Professional-Oriented Signal Management

The PiloTone and NoiseLocke circuits contribute to signal management and interference reduction when the RF link is not optimal. The goal is to maintain clean and controlled reproduction, avoiding unintended openings and unwanted artifacts.

Connectivity: Simple Integration into Consoles or Audio Systems

With an XLR output and a 6.35mm Jack output, the ACT-311II easily adapts to common configurations: connection to a mixing console, amplifier, processor, or audio interface. This dual connectivity is practical for accommodating different equipment levels, whether in performance or installation.
