The AT4049b Omnidirectional Condenser Microphone from Audio-Technica is specifically designed for professional recording, live broadcast, and other miking applications where reliability is critical such as sound reinforcement. This versatile mic features direct-coupled balanced outputs, providing a clean signal in high-output conditions without the distortion that is normally associated with conventional transformer-coupled outputs. Its transformerless circuitry design minimizes low-frequency distortions and optimizes the correlation of high-speed transients.

Its omnidirectional polar pattern picks up the maximum ambient atmosphere for the sound of your venue. Its efficient transient response transparently reproduces even the most difficult-to-capture instruments. The AT4049b also includes a switchable 80 Hz high-pass filter and a 10 dB pad.

Featuring a rugged housing of turned brass, every AT4049b features innovative design and exemplary manufacturing quality complies with Audio-Technica’s stringent standards of consistency and reliability. The AT4049b consists of two modular subassemblies: an AT4900b-48 body and an AT4049b-EL omnidirectional head capsule (both body and capsule are sold separately). The AT4049b mic comes with a custom AT8405a stand clamp for 5/8"-27 threaded stands—which helps further isolate the mic from handling noise—as well as a windscreen to minimize vocal plosives and a protective carrying case for secure transportation and safe storage. Additional capsules are also sold separately: cardioid (AT4051b-EL) and hypercardioid (AT4053b-EL).
