MIPRO has expanded its acclaimed MI-58 Series 5.8 GHz digital in-ear monitoring (IEM) system with the introduction of the AD-58 5 GHz 4-Channel transmitting antenna combiner. Designed to meet the demanding needs of live performers, engineers, and interpretation professionals, the MI-58 Series is celebrated for its wide frequency response, low latency, and refined audio clarity.
The MI-58 digital stereo wireless IEM system includes the MI-58R / MI-580R stereo bodypack receiver, the MI-58T / MI-58TD stereo transmitter, and optional noise-isolating earphones. With features such as a user-friendly control panel, long-distance signal transmission, and selectable Stereo / Mono / Mixed output modes, the system offers versatile monitoring solutions tailored to both stage performers and interpretation settings.
The MI-580R receiver supports two AA-type batteries or a rechargeable Li-ion battery with USB Type-C charging via a patented, foolproof charging circuit. A 3.5 mm TRS output delivers up to 100 mW @ 16 Ω, with optional standard or professional isolating earphones.
The MI-58T / MI-58TD transmitter offers comprehensive control and intuitive design. It includes a graphic OLED screen, rotary control, ACT™ sync, dual headphone monitoring outputs (3.5 mm and 6.3 mm), and volume knobs. The rear panel houses XLR / 6.3 mm combo inputs, loop outputs, TNC RF connectors, and an optional Dante interface for the MI-58TD. Transmit power is rated < 25 mW, depending on local telecom regulations.
A key feature for engineers is the dedicated ENG MODE, providing full control during live performances.
New AD-58 Antenna Combiner Enhances Multi-System Integration
In addition to the AT-58 5 GHz Directional Log Antenna, which helps extend system coverage and improve signal focus, the MI-58 Series now welcomes the new AD-58 5 GHz Antenna Combiner. Operating within the ISM 5.6–5.9 GHz band, the AD-58 integrates up to four MI-58T / MI-58TD transmitters into a single output antenna with 10 dB gain. This reduces antenna congestion and minimizes the need for multiple power supplies—ideal for complex stage setups and large-scale applications.
RF LED indicators per channel clearly show signal presence and overload status, providing real-time monitoring at a glance. By streamlining antenna installations and significantly reducing intermodulation interference, the AD-58 ensures greater stability and optimal performance in demanding multi-transmitter environments.
