The 19-inch rack-mountable unit features a bright, comprehensive LCD display and balanced XLR outputs on the rear panel.
Dual Transmitter Operation
The U4D dual receiver enables simultaneous operation of 2 microphone transmitters.
Marcad Diversity Operation
Shure's patented Marcad circuitry minimizes RF noise and drop-out.
2400 Selectable Frequencies

Here's Your Sound. It's where we meet. Shure has been enthusiastically dedicated to helping you tell the truth in notes, words and sound since 1925. We make microphones and audio electronics to help amplify, process, and mix your sound. Perfectly. Transparently. Reliably.
This success is and always has been due to our recognition that audio electronics are the means to self-expression for a diverse group of individuals worldwide. Without the desire of so many to have their unique voices heard, there would be no Shure Incorporated. Now, past our 75th year, we re-dedicate ourselves to this notion of being the audio tool of choice for personal expression, reminding ourselves that "Shure" is synonymous with "your sound."
Our history is one of innovation and excellence. For instance, our SM57 and SM58 mics are still the world's top sellers - over 30 years after they were introduced. Our products are, quite simply, the tried and true products of genius. Of course, there's a lot more to the story. Click here for a Brief History of Shure.
So, what do we make? Lots of great gear for stage and studio: Microphones. Wireless microphones and wireless guitar systems. Digital signal processors and feedback eliminators. Personal (in-ear) monitor systems. Hi-Fi phono cartridges and DJ needles. Portable mixers and digital signal processors.
If you're here because you're a musician (or speaker or engineer or sound technician), you've come to the right place. It's nice to meet you. Because you and Shure, we've got something in common.
Used Speaker Accessories
Speakers are generally output devices used by computer systems, and these usually have speaker accessories such as speaker hardware, cables, mounts, stands, etc. All speakersâ?? function amplify sound or audio output so it can be heard by other listeners easier. There are speakers that are built to work particularly with computers while there are those that can be linked to any kind of sound system device. The speakers function as transducers that transform electromagnetic waves into sound waves that can be heard by listeners. They receive audio input from source devices like the computer and with the use of speaker accessories the sound is amplified. Analog sound waves are converted into digital sound waves and are produced from digital speakers.
The speaker cables serve as connectors between the input devices and the speaker. Computers and other audio devices will need compatible cables to be able to connect with the speakers and produce amplified sound. The speaker mount are speaker accessories that act as support. They are needed to properly place and hold speakers so they can function properly. There are wall mounts and brackets for the ceiling. Different mounts are needed for different sizes and location for placement. The speaker stand is commonly used in surround systems and these are speaker accessories that help position the speaker devices efficiently. These are usually adjustable. The speaker rigging comprises the support system of speakers. Normally, if there is not rigging provided, the speakers are simply stacked on top of the other on stage.
