Product Details

Audio-Technica AT4049B Omnidirectional Condenser Microphone

The Audio-Technica AT4049B is a versatile omnidirectional condenser microphone recommended for professional recording and critical applications in broadcast. Use the AT4049B mic with confidence in a wide variety of professional miking applications, such as acoustic instruments and percussion, where proximity effect and coloration are not desired; ambient recording for clean room sound free from off-axis coloration; and distance miking of electric guitars and other instruments in great-sounding live rooms. The greatest advantage of omni mics in general and the AT4049B in particular, is the open and extended bass response and lack of phase-cancellation problems that can occur with directional mics.

Featuring direct-coupled balanced outputs for clean signals in high-output conditions, the Audio AT4049B microphone is totally free of the distortion associated with conventional transformer-coupled outputs. Its fast response to transients contributes to the open, transparent reproduction of even the most difficult-to-capture instruments. The AT4049B microphone is fully RoHS-compliant—free from all substances specified in the EU directive on the reduction of hazardous substances (RoHS).
The Audio-Technica AT4049B consists of 2 modular subassemblies: an AT4900b-48 body and an AT4049b-EL omnidirectional microphone head capsule.
