Designed for professional speech reinforcement, presentations, theater, and live events, this system delivers clear vocal reproduction while allowing presenters and performers to move freely without a handheld microphone.
Featuring the Shure MX153 omnidirectional earset microphone, BLX1 bodypack transmitter, and BLX4R rackmount receiver, the BLX14R/MX53 is an excellent choice for houses of worship, corporate meeting facilities, educational institutions, and professional performance venues.
Its lightweight, low-profile microphone design provides comfortable extended wear, while one-touch QuickScan frequency selection makes wireless setup straightforward.
Shure MX153 Omnidirectional Earset Microphone
The included Shure MX153 is a professional subminiature earset microphone designed for discreet placement near the mouth.
Its omnidirectional pickup pattern captures speech consistently while allowing natural head movement. The lightweight, flexible design makes it suitable for presentations, performances, and extended speaking engagements.
Unlike traditional over-the-head headsets, the MX153 features an earset design that fits over one ear, providing a less noticeable appearance for speakers and performers.
Clear, Natural Speech Reproduction
The MX153 condenser microphone is designed for professional vocal applications where intelligibility and consistent sound quality are essential.
Its discreet placement helps maintain a natural appearance during video presentations, theatrical performances, and public speaking events.
BLX4R Rackmount Wireless Receiver
The Shure BLX4R is a single-channel wireless receiver designed for professional sound reinforcement applications.
Its rackmount configuration allows convenient installation in portable audio racks and permanent sound systems.
One-Touch QuickScan Frequency Selection
Shure QuickScan automatically searches for an available operating frequency within the system's supported frequency band.
This simplifies setup and helps reduce the time needed to configure wireless microphones before performances, meetings, and events.
Professional Audio Connections
The BLX4R provides both XLR and 1/4-inch audio outputs for connection to compatible mixers and professional sound systems.
Included rackmount hardware makes the receiver suitable for installation in standard equipment racks.
BLX1 Bodypack Transmitter for Wireless Freedom
The included Shure BLX1 bodypack transmitter provides a compact wireless connection for the MX153 earset microphone.
Powered by two AA batteries, the transmitter offers up to 14 hours of battery life, depending on battery type and operating conditions.
Its lightweight design allows presenters, instructors, and performers to move naturally throughout their presentations or performances.
