Product Introduction

The MIPRO ACT-545 4-Channel UHF Wireless Microphone System (Hybrid Setup) combines 2 handheld microphones (ACT-500H) and 2 lavalier clip microphones (ACT-500T) into one powerful and flexible wireless solution. Designed for churches, conferences, training sessions, and live events, this system provides maximum versatility for different speaking and performance needs.

Built with a rugged EIA standard 19” rack-mount metal chassis and powered by advanced True Diversity technology, the ACT-545 ensures long-range, stable, and interference-free wireless performance.

 Product Description

The MIPRO ACT-545 is engineered using advanced wireless technology inherited from the professional ACT-7 series. Its 24 MHz narrowband true diversity receiving circuit minimizes signal dropouts and intermodulation distortion while maximizing stable channel availability in crowded RF environments.

The front panel features a modern dual-color backlit LCD display that automatically changes color to indicate “Working” or “Standby” mode. A rotary control knob and intuitive buttons provide quick and easy system operation.

With MIPRO Auto Scan and ACT™ synchronization, frequency pairing between transmitters and receiver is fast and precise. The system includes 7 preset groups (80 frequencies) and allows user-defined selection of up to 16 channels from 961 available frequencies, offering excellent flexibility.

Each channel provides independent audio outputs with selectable gain levels or a mixed output option, ensuring optimal signal integrity and dynamic range without distortion.

The system also supports an optional Dante network interface, making it ready for modern AV-over-IP installations. The hybrid combination of handheld and lavalier microphones makes it suitable for both speech and performance applications.
