AT4049B Omnidirekcioni kondenzatorski mikrofon
Preporučuje se za profesionalna snimanja i kritične aplikacije pri emitovanju.
Omnidirekcioni polarni obrazac obezbeđuje maksimalno ambijentalno upijanje.
Recommended for professional recording and critical applications in broadcast, this versatile microphone may be used with confidence in a wide variety of professional miking applications. Featuring direct-coupled balanced outputs for clean signals in high-output conditions, the 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 microphone is fully RoHS-compliant - free from all substances specified in the EU directive on the reduction of hazardous substances (RoHS).
The AT4049b consists of two modular subassemblies: an AT4900b-48 body and an AT4049b-EL omnidirectional head capsule (both available separately). Additional interchangeable capsules are available in cardioid (AT4051b-EL) and hypercardioid (AT4053b-EL).
