Mipro ACT-545

A Receiver Designed for Professional Integration within the ACT Ecosystem

The Mipro ACT-545 is designed with a professional approach: a metal chassis in standard EIA format, reliability-focused design, and connectors intended for clean integration into a sound rack, mobile control room, or fixed installation. In a modern RF setup, reception stability and consistent audio levels are essential; the ACT-545 positions itself as a UHF receiver built to meet field demands, with the possibility to extend the architecture towards network audio via Dante (optional).

Who Benefits from the ACT-545 and in What Applications

This receiver targets sound engineers, service providers, performance venues, conference and audiovisual installations seeking more reliable RF reception, especially when radio conditions are variable (multiple RF sources, movement, complex stages). Its true diversity reception and detachable antennas facilitate system optimization, while the balanced and unbalanced outputs allow adaptation to consoles, stageboxes, or audio interfaces according to cabling preferences.

Key Features: RF Stability, Audio Consistency, and Integration

True Diversity Reception: A Solid Foundation in UHF

The true diversity reception mode aims to secure reception by using two reception paths, reducing dropouts and improving signal continuity in spaces where reflections and masking may occur. Combined with a 24 MHz bandwidth in UHF, the ACT-545 is designed to fit into RF parks and technical environments where more comfortable frequency management is sought.

Audio Quality and Dynamic Headroom

For natural voice and instrument reproduction, the ACT-545 offers a frequency response from 50 Hz to 18 kHz, with a dynamic range greater than 111 dBA. These elements help maintain precision, attack, and clarity while limiting the sensation of compression when the source becomes more expressive.

Audio Outputs: Balanced and Unbalanced with Selectable Levels

The ACT-545 provides a balanced output and an unbalanced output, each with three level settings. This flexibility is particularly useful to match the input level of a console, stagebox, or processor, and to harmonize levels when multiple receivers coexist in the same rack.

Dante Option: Opening to Network Audio

When infrastructure requires, the ACT-545 can be equipped with a Dante network interface (optional). This approach enables more modular deployments, with audio distribution designed for AV environments and installations where audio over IP simplifies routing and system evolution.

Detachable Antennas and Rack Integration

Detachable antennas facilitate reception optimization depending on rack placement. The receiver features a female TNC 50? connector providing bias for MIPRO antenna systems, supporting the implementation of antenna solutions suited to more ambitious installations. All is housed in a metal chassis with EIA standard, suitable for road use as well as technical racks.

Universal Power Supply, Designed for the Field

The ACT-545 operates via an external switching power supply compatible with 100 to 240 V AC, a valuable feature for events and tours where stability and mains compatibility are prerequisites.
