The Beta 181 Microphone Kit from Shure includes a Beta 181 handheld XLR preamplifier and interchangeable side-address cardioid, supercardioid, bi-directional, and omnidirectional condenser capsules. This line-up of capsules allows you to use the Beta 181 on a variety of sources ranging from drum overheads to piano to acoustic instruments and vocals.Shure RPM181/PRE Replacement XLR PreamplifierThe RPM181/PRE Replacement XLR Preamplifier by Shure is designed to work in combination with one of four interchangeable capsules for the Shure Beta 181 side-address instrument microphone. The capsules come in cardioid, supercardioid, omnidirectional and bidirectional Polar patterns making a highly versatile pair.
With a capsule attached, it weighs only 5.1 oz and gets close to any source even in the tightest conditions. Its wide frequency response and high SPL handling is great for miking dual sound sources such as between toms or acoustic instruments. It is also very useful as a mono drum overhead or pair two to create the Blumlein stereo effect.
The RPM181/PRE matched with any of the available capsules performs with little to no crossover distortion and provides exceptional low-frequency reproduction. The pair provides exceptional audio with consistent, textbook-like Polar responses resulting in a mic with noteworthy sound and versatility.Works with one of four interchangeable capsules for the Shure Beta 181 instrument microphoneThe cardioid, supercardioid, omnidirectional and bidirectional capsules make this mic highly versatileWeighs only 5.1 oz with attached capsule and captures any source even in the tightest conditionsMatched with any available capsule it performs with little to no crossover distortion and provides exceptional low-frequency reproductionShure RPM181/C Cardioid Polar Pattern CapsuleThe RPM181/C Cardioid Polar Pattern Capsule by Shure is one of four interchangeable capsules for Shure’s Beta 181 side-address instrument microphone. It features a locking ring which provides a secure connection with the Shure RPM181/PRE. Paired with this preamp, its compact design weighs only 5.1 oz and gets close to any source even in the tightest conditions. With its wide frequency response and high SPL handling, it’s great for piano, acoustic instruments, or used as a drum overhead. It also performs with little to no crossover distortion and provides exceptional low-frequency reproduction. The capsule is made with a hardened steel mesh grille that resists denting, wear and abuse.
