The AT4049b Omnidirectional Condenser Microphone from Audio-Technica consists of the company's AT4900b-48 microphone body and the AT4049b-EL omnidirectional head capsule. It is suitable for field or studio use and features an omnidirectional pickup pattern that detects sounds in all directions, allowing you to record room ambience. The microphone's internal transformerless circuitry reduces distortion and provides correlation of high-speed transients. There is a direct-coupled balanced output for a clean signal under high-output conditions and a strong turned-brass housing for durability. A switchable high-pass filter reduces low frequency noise, and a -10 dB pad picks up loud sound sources. The package includes a microphone stand clamp, a windscreen, and carrying case.
