The Audio-Technica AT4053B-EL Cardioid head capsule is a modular component of the Audio-Technica AT4053B, AT4049B, and AT4951B Condenser Microphone systems. The AT4053B-EL is one of several capsules designed to work with the Audio-Technica AT4900b-48 microphone body. It is recommended for professional recording and critical applications in broadcast. The 4053b-EL has fast response to transients and contributes to the open, transparent reproduction of even the most difficult-to-capture instruments.The excellent rear rejection of the AT5053B"s hypercardioid pattern makes it great for live sound instrument recording, where additional rear-rejection is required.
