About this model
The Audio-Technica AT4051B Cardioid Condenser Microphone is ideal for professional recording and critical applications in broadcast. Featuring direct-coupled balanced outputs for clean signals in high-output conditions, the AT4051B 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 AT4051B mic is fully RoHS-compliant”free from all substances specified in the EU directive on the reduction of hazardous substances (RoHS). The AT4051b consists of two modular subassemblies: an AT4900b-48 body and an AT4051b-EL cardioid head capsule. Recommended uses of the AT4051B are acoustic guitar, percussion, drum overheads (mainly for cymbals), and live-sound instrument recording where rear-cancellation is required.
