Shure BLX® wireless rack-mount presenter system provides a sound solution to free up your hands and make yourself mobile while speaking. Microphone earset connects to the bodypack transmitter, which can operate up to 300 feet away (line of sight) from the receiver. Professional quality and simple setup with an intuitive interface come together to create legendary audio performance right out of the box. These features and more make this wireless system a great choice for lecturers and presenters, worship leaders, actors in community theatres, and more.

The Shure BLX14R/MX53 wireless microphone system communicates between the BLX4R receiver and the BLX1 bodypack transmitter. Rack mount receiver fits neatly into an existing setup or on its own. QuickScan frequency selection finds the best available frequency for the receiver and transmitter with just one touch at setup. In addition to fast frequency selection, this analog receiver delivers improved linearity and frequency response. LED indicators on the receiver display the status of audio levels so gain can be adjusted as needed. The rack mount kit is included, and the antennas are removable for quick antenna distribution.

Paired to the receiver is the BLX1 bodypack transmitter. Worn either on a belt or a guitar strap, this bodypack transmitter is lightweight and will go unnoticed by audiences and speakers alike. With a battery life of up to 14 hours and an LED indicator for low battery level, this wireless system lasts through even long uses. Functions such as group and channel selection and gain adjustment can be done right from the bodypack transmitter. The on/off switch is easily accessible and uses a toggle design, providing tactile indication when the transmitter is on.

Subminiature microphone MX153 offers exceptional speech clarity and enhanced plosive protection in a comfortable earset design. Improved gain before feedback makes this omnidirectional mic ideal for business presentations, A/V conferences, houses of worship, and live sound reinforcement. Protective elements include Kevlar reinforced cable, windscreens, and CommShield® Technology that guards against interference from digital bodypack transmitters and RF cellular devices.
