A solution inspired by the "SM" reference: simplicity, robustness, and consistency
The SM Wireless analog systems follow the spirit of the SM series microphones, which have become a benchmark among professionals for their consistency and reliability. Here, the goal is clear: to offer a wireless system that is easy to deploy, stable in use, and flexible enough to adapt to stage needs as well as event environments. The M17 Band fits into a multi-pack approach, with a range organized into 21 complete sets, including versions dedicated to intensive uses such as fitness.
Who is it for? Fitness classes, coaching, sports animation, and projected voice
This " special fitness instructor" pack is tailored for situations where speaking while moving is required: group classes, coaching, studios, associations, sporting events, or animation. The headset microphone frees the hands, stabilizes the distance to the mouth, and helps maintain intelligible voice even when intensity increases. The choice of a rackable receiver also facilitates integration into a control room, technical cabinet, or fixed installation with mixer and amplifiers.
