🔊 Product Introduction

The MIPRO ACT-545 4-Channel UHF Wireless Lavalier Microphone System is a professional-grade audio solution designed for conferences, training sessions, churches, and live presentations. Built with a durable EIA standard 19-inch metal chassis and a modern dual-color LCD interface, this system delivers exceptional reliability, flexibility, and crystal-clear sound.

Equipped with advanced True Diversity technology, the ACT-545 ensures long-range, stable signal reception without dropouts, making it ideal for professional AV installations and system integrators.

📝 Product Description

The MIPRO ACT-545 incorporates cutting-edge wireless technology derived from the renowned ACT-7 series. Its 24 MHz narrowband true diversity receiving circuit significantly reduces interference and intermodulation distortion, ensuring stable wireless performance even in complex RF environments.

The front panel features a newly designed dual-color backlit LCD display, which automatically changes color to indicate “Working” or “Standby” status. A rotary control knob and intuitive buttons allow for quick and easy operation.

With MIPRO Auto Scan and ACT™ synchronization, frequency setup is fast and precise. The system offers 7 preset groups with 80 pre-saved frequencies, along with a user-defined group that allows selection of up to 16 channels from 961 available frequencies, providing maximum flexibility.

Each channel supports independent audio outputs with selectable gain levels or a mixed output option, ensuring optimal signal performance without distortion. The system also supports an optional Dante network interface, making it suitable for modern AV-over-IP installations.

Paired with ACT-500T bodypack transmitters (lavalier / clip microphones), this system is perfect for hands-free applications, delivering clear speech reproduction and consistent performance.
