A Discreet Overhead Mic Package

The MicroBoom MB5050 gives you the Audix 50" MicroBoom arm with their high-quality MB5050 mini cardioid condenser mic - a great all-in-one package for overhead stage miking of orchestras and choirs, ambient room miking, drum-miking, and more. The boom in the MicroBoom MB5050 package can be used in either a horizontal or a vertical position, while the upper end of the boom holds a mini-XLR connector to securely hold the mic in place. The mic has a built-in low noise preamplifier so no bulky external supply is needed. If you want a clean, professional, and elegant miking solution, you'll find it with the Audix MicroBoom MB5050.

The Audix M5050 delivers superb sound. It has a fully integrated preamp and detachable cable, as well as strong shielding from interference. It's a great overhead mic for choir and group vocals, on acoustic instruments, for ambient room miking, symphonic area miking, speech presentations, cymbals, and more.

The MicroBoom arm combines with the M1250 condenser microphone to become an ideal solution for discreet, overhead miking. This 50-inch carbon fiber boom attaches to any microphone stand, and it weighs in at only 2.5 ounces. Carbon fiber is one of the most lightweight and durable materials on the planet - which is why it's being used to make parts for race bikes, aerospace crafts, motorcycles, and more. The MicroBoom is certainly discrete, but it's also rugged - it has a mini-XLR connector to securely hold the microphone in place while high-quality Mogami cable is used internally to deliver excellent sound to the bottom of the boom, where a mini-XLR male connector awaits.

Very pleased with Audix mb5050 mics

Mics are doing the job required and very pleased with overall performance.
Music background: instrumental/vocal director

Small choir

We have a small choir at our church, and we have some that cannot attend the services so we record the services for them. Each Christmas and Easter we do special music and could not get get a good recording of the choir voices. This new new mic is great, I have heard from the recording listeners that this year was a great improvement in sound quality, and it only took minutes to set up.
