POWER ACOUSTICS SONORISATION WM 7000 FITNESS 631.7

A system designed for classes on the move

The WM 7000 FITNESS 631.7 is presented as a high-end wireless system designed for sports instruction. Its distinctive feature is the integration of the transmitter directly into the headset. This design eliminates the need to find a place for a separate bodypack on sportswear and meets the demands of an activity involving constant body movement.

To lead a session without tying up your hands

This wireless fitness microphone is aimed at coaches, dance teachers and instructors who need to give instructions while demonstrating exercises. The headset format keeps the microphone close to the mouth during demonstrations, without having to hold a microphone or manage the cable of a wired microphone.

Its compact and lightweight transmitter prioritizes freedom of movement. The stated range of 60 m provides useful freedom to move around, subject to the actual conditions in the room. As with any radio link, obstacles, the electromagnetic environment and the positioning of the receiver can affect transmission.

UHF transmission and accessible controls

Infrared synchronization and LED monitoring

The single-channel UHF receiver operates with FM modulation. Infrared synchronization makes it easier to pair with the transmitter, while the LED indicators allow you to monitor the system's operation. An integrated interference-limiting device completes the setup, although choosing a suitable location for the receiver remains important.

Two sensitivity settings for adjusting voice pickup

The microphone offers two sensitivity settings. This choice allows you to adapt the pickup to the user's voice level before fine-tuning the volume on the sound system. The stated audio response ranges from 70 Hz to 15 kHz, with a dynamic range greater than 102 dB and an A-weighted signal-to-noise ratio greater than 98 dB.

Two output formats for connection to a sound system

The receiver features an XLR output and a 6.35 mm Jack output. These two formats allow you to choose the connection that matches the available input on a mixing console or powered speaker. The headset transmitter is powered by a 1.5 V AAA battery; the receiver is powered via a 12 V adapter.
