Audio-Technica AT4040 - Cardioid Condenser Studio Microphone with Shock Mount

The Audio-Technica AT4040 is a side-address cardioid condenser microphone from the 40 Series for professional recording, broadcast and sound reinforcement. A large, tensioned diaphragm gives smooth, natural sound, and transformerless circuitry reduces low-frequency distortion.

It combines very low self-noise, wide dynamic range and high SPL capability with a switchable 80 Hz high-pass filter and 10 dB pad. The AT8449a shock mount is included.
