A versatile mic suitable for critical recording, broadcast, and room ambience capture.
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.
- Specially engineered to meet the most critical acoustic requirements of professional recording, broadcast, and live classical recording.
- Omnidirectional polar pattern provides maximum ambient pickup
- Direct-coupled, balanced output results in a clean signal even under high-output conditions
- Transformerless circuitry virtually eliminates low-frequency distortion and provides superior correlation of high-speed transients
- Switchable 80 Hz hi-pass filter and 10 dB pad
- Rugged turned-brass microphone housing for enduring dependability
- State-of-the-art design and manufacturing techniques ensure compliance with A-T's stringent consistency and reliability standards
- RoHS-compliant — free from all substances specified in the EU directive on the reduction of hazardous substances (RoHS)
Every mic locker should have at least one good pair of omni's - make yours the AT4049b.
