MIPRO MI-58T IEM 5 GHz Digital Stereo Transmitter

The MI-58T is a 5.8 GHz digital stereo in-ear monitor transmitter delivering stable, low-latency performance with Stereo / Mono selection. It features XLR / 6.3 mm combo inputs and an OLED interface for stage and portable monitoring.
- Engineered for interference-free performance, the MI-58T operates in the license-free ISM 5 GHz band with high-efficiency digital modulation for stable, high-fidelity transmission.
- Features two selectable groups: Group A with 12 channels, and Group B with subgroups B1 and B2, each offering 12 channels—allowing flexible frequency planning for complex venues.
- Each channel supports 64 user IDs and one encrypted ID, enabling multiple systems to operate in close proximity without crosstalk.
- Equipped with an OLED display and a rotaty knob for intuitive navigation, with a lock function to prevent accidental changes.
- XLR / 6.3 mm combo input accommodates both balanced and unbalanced sources; 6.3 mm LOOP OUT allows easy signal routing to additional equipment.
- Includes 6.3 mm and 3.5 mm headphone outputs with adjustable volume for convenient real-time monitoring.
- Multiple transmitters can be paired with the AD-58 antenna combiner and external antennas to extend range and enhance signal stability.
- ENG mode enables quick data transfer to multiple receivers, allowing sound engineers to configure and monitor systems on the fly.
