Audio Reference Companding
Audio Reference Companding is a level-dependent companding scheme. Instead of companding across the entire dynamic range like most wireless systems (causing a whooshing audio artifact known as "breathing"), companding only occurs at high audio levels. These levels are high enough to make the companding artifacts inaudible.

Beta 58 Microphone Cartridge
The Shure Beta 58A is a high-output supercardioid dynamic vocal microphone designed for professional sound reinforcement and project studio recording. It maintains a true supercardioid pattern throughout its frequency range. This insures high gain-before-feedback, maximum isolation from other sound sources, and minimum off-axis tone coloration. The Beta 58A has a shaped frequency response that is ideal for close-up vocals. The superb performance of this microphone is not affected by rough handling because of its rugged construction, proven shock mount system, and hardened steel mesh grille. Typical applications for the Beta 58A include lead vocals, backup vocals and speech.

• Smooth, extended frequency response for outstanding sound for professional live vocal use
• Consistent supercardioid pattern provides the best gain-before-feedback among dynamic microphones
• Pneumatic shock mount reduces handling noise
• Frequency response: 50 to 16,000 Hz
