Cardioid Condenser Microphone
Product Description
A marriage of technical precision and artistic inspiration, the AT4040 features an advanced large diaphragm, tensioned specifically to provide smooth, natural sonic characteristics. Designed as a multi-purpose performer, this externally polarized (DC bias) true condenser microphone offers exceptionally low noise, wide dynamic range and high SPL capability for greatest versatility. Being symmetrical and transformerless 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 troublesome of instruments and sound effects.
