This system embodies the spirit of the BLX range: providing a wireless solution that is simple to deploy, reliable for daily use, and perfectly suited to the needs of group classes. The combination of the BLX4E receiver and BLX1 belt transmitter forms an intuitive base, while the SM31FH headset microphone offers a practical response to sports constraints: humidity, rapid movements, and the need to maintain intelligible diction without straining the voice.
This pack is ideal for the fitness instructor, sports coach, HIIT, cycling, step, functional training class leader, or any activity involving continuous speaking while moving. The headset format allows for hands-free operation and a stable mouth-to-microphone distance, which helps maintain a consistent level and improve instruction clarity. Thanks to its cardioid directivity, the microphone is especially relevant when the music is loud or the room is noisy.
The SM31FH headset microphone is built to withstand the demanding conditions of an intensive class. Its hydrophobic design helps better manage sweat and moisture while maintaining voice-focused pickup. The result: clearer announcements, less vocal fatigue, and a more consistent presence even when the instructor moves around the room.
In shared environments (studio, multipurpose room, simultaneous classes), frequency availability can vary. The system includes a frequency scanner and QuickScan synchronization to speed up the selection of an available channel and transmitter/receiver pairing. This is a real time saver before a class, especially when running multiple sessions in a day.
The transmission is analog, and the system supports up to 12 systems operating simultaneously. For organizations with multiple rooms or instructors, this allows for a coherent setup, provided the frequency range of the model is respected. Here, the H8E band covers 518 to 542 MHz.
