Mipro MI-58RT

Mipro's MI-58RT in-ear monitoring set combines the series' digital transmitter and compact bodypack receiver. The MI-58 system is aimed at musicians who demand clean and transparent monitoring audio, without the artefacts typical for analogue wireless systems: Because the entire signal path is digital, the sound is free of compression or other technical side-effects that can alter or distort it. Similarly, the connection between the transmitter and the receiver is stable and reliable, with a latency of less than 4ms, which is scarcely audible. As the name suggests, the MI-58 series uses the 5.8GHz frequency band, which is free to use without a licence worldwide – another reason the system is so popular in mobile setups, for smaller stages or rehearsal spaces, or in permanently installed setups.

The Mipro MI-58R bodypack is robust and compact – intended for continuous stage use. The receiver comes with a set of in-ear headphones, so that even beginners have everything they need to get started straight out of the box. It's powered by a rechargeable battery and charged using the docking station also included. There are a number of key settings that musicians themselves can adjust on the receiver. Besides volume control, functions include fine-tuning the sound, including optimising the highs and lows to personal preference – this really helps make the most of the system's excellent signal quality. Another feature with a genuine practical benefit is the balance function: When receiving a mono-mix signal, made up for instance of separate vocal and instrument channels, a performer can precisely set the relative level of the two sources.

Combining near-effortless setup, crystal-clear signal, and stage-ready construction, the MI-58 is an IEM system that can play to its strengths whatever the setting. The transmitter has a set of versatile connections that enable a variety of monitoring setups: The combo jacks on the rear accept XLR mic cables and 6.3mm instrument lines, either as a stereo signal or as a mono monitor feed. Further flexibility is provided by the system's deliberate modularity – more receivers can be added almost without restrictions, and multiple transmitters can also be linked and controlled as one unit, which is a major benefit for larger rigs or permanent installations. But it's still the performance of the technology itself which is most noteworthy here, with the high-quality, low-latency transmission making it suited for all kinds of signals, including vocals and rhythmically unforgiving instruments like drums. All in all, the Mipro MI-58RT offers a coherent balance of clear audio, straightforward operation, and a well‑implemented wireless platform.
