Mipro MI-58 Twin Set

Mipro's MI-58 series 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. The MI-58 Twin Set here combines the system's key components – the stereo transmitter and a wireless receiver – with another receiver that comes with its own charging station and headphones. The transmitter's flexible audio inputs mean two performers can either receive the same stereo signal or their own mono source. 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 bodypacks are robust and compact – intended for continuous stage use. The receivers each come with a set of in-ear headphones, so that even beginners have everything they need to get started straight out of the box. They're powered by a rechargeable battery and charged using the docking stations 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-58 series offers a coherent balance of clear audio, straightforward operation, and a well‑implemented wireless platform.
