AKG WMS45 Sports Set Perception A

AKG WMS45 Sports Set Perception A — UHF Wireless Headworn Microphone System

The AKG WMS45 Sports Set Perception A delivers hands-free wireless audio for instructors, coaches, and active presenters who move around while they speak. Operating in the UHF band from 530.025 to 559 MHz, this system gives users the freedom to lead a class, run a training session, or guide a tour without being tethered to a cable. The Perception Wireless Sports Set combines the SR45 receiver, PT45 bodypack transmitter, and C544 L headworn microphone into a single ready-to-use package that is surprisingly easy to set up.

Built for Active, Hands-Free Use

The C544 L condenser microphone features an external shock mount that suppresses cable and mechanical noise, so movement does not translate into distracting thumps in the mix. A moisture shield on the capsule keeps sweat and humidity from penetrating the transducer, making this set well suited to gym floors and outdoor sessions. The PT45 bodypack is the smallest and lightest transmitter in its class, and it is also compatible with all AKG MicroMics for future expansion.

Ideal for Fitness Instructors, Coaches, and Active Presenters
