Wireless Microphone
This package brings together the precision of the MU-55 HNSP and the reliability of Mipro's wireless transmission technology to create a package calibrated for clear, mobile vocals. The MU-55 HNSP's ultra-thin headband hugs the head without constraint, while its condenser capsule captures every nuance with naturalness and balance. This discreetly-profiled headband microphone is moisture-resistant thanks to its special treatment, and remains stable even under the pressure of an intensive class or dynamic stage. The ACT-33TW transmitter, compact and waterproof, instantly synchronises the carrier frequency with the ACT-311II receiver via the ACT function, ensuring True Diversity capture with formidable stability. Together, this trio is made for lively voices, fast movement and demanding environments. A set designed to be forgotten... except for the quality of the sound it delivers.

Composition of the package
Presentation
The MU-55 HNSP incorporates a 4.5 mm condenser capsule that captures the full spectrum from 40 Hz to 20 kHz, with no loss of clarity. Its omnidirectional pick-up pattern reproduces speech with impressive naturalness, even when you move or change direction. During a sports lesson or a lively lecture, the slim headband and lightweight frame ensure lasting comfort, while the swivelling capsule allows precise positioning. This mechanical precision reveals Mipro's mastery of designing accessories dedicated to the voice.

The ACT-33TW transmitter, designed to accompany long performances, features a robust, waterproof design with IP67 certification. Compact and lightweight, it can be clipped to a belt using an ergonomic clip, and maintains exemplary signal stability in the 480-934 MHz UHF band. The ACT system ensures ultra-fast synchronisation with the receiver, and the LED battery indicators guarantee clear reading even in the dark backstage.
Paragraph 3: 870 characters / 129 words
The ACT-311II receiver, at the heart of the system, operates in True Diversity mode to maintain a seamless link, even in frequency-saturated environments. Its backlit LCD display makes it easy to navigate between the 7 groups and 80 frequencies available, while XLR and ∅6.35 mm jack outputs ensure full compatibility with stage consoles and amps. Its half-rack 19" format optimises integration into both fixed and mobile installations, while preserving linear audio quality from 50 Hz to 18 kHz.
Paragraph 4: 680 characters / 104 words
By combining the three elements of the pack, you get a complete wireless solution: a stable, lightweight headset microphone, a sweat-resistant transmitter and a receiver with formidable precision. This system is ready to follow every word, every movement and every breath, without interruption. Mipro has designed this trio for presenters, coaches, speakers and anyone who uses their voice as a performance tool.

Add a spare windscreen to extend the life of the capsule and avoid stray wind during your performances.

And don't forget to store your pack in a padded hard case, to protect the connectors and extend the reliability of the system.
Paragraph 2: 600 characters / 89 words
Regularly clean the MU-55 HNSP headband with a soft, slightly damp cloth to keep it comfortable and supple. Change the ACT-33TW's batteries before each major use, to avoid any unexpected disconnection. And adjust the position of the capsule to suit the shape of your face, for greater vocal precision without straining your voice, even after long hours of use.
