The MI-58 series 5.8 GHz digital in-ear monitoring system has now introduced an AD-58 5 GHz four-channel transmitting antenna combiner to meet the needs of interpreters, engineers and live performers.
The MI-58 digital stereo wireless IEM system includes the MI-58R/MI-580R stereo bodypack receiver, the MI-58T/MI58TD stereo transmitter, and optional noise-isolating earphones, including features
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.
A graphic OLED screen is included, alongside rotary control, ACT sync, dual headphone monitoring outputs (3.5mm and 6.3mm) and volume knobs.
The rear panel features XLR/6.3mm 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.
The AD-58 5 GHz antenna combiner operates within the ISM 5.6-5.9 GHz band, allowing the AD-58 to integrate up to four MI-58T/MI-58TD transmitters into a single output antenna with 10dB gain, reducing antenna congestion and minimising the need for multiple power supplies in complex stage setups and large-scale applications.
RF LED indicators per channel identify signal presence and overload status, adding real-time monitoring at a brief glance.
