The Audio-Technica AT4040 is a premier large-diaphragm studio condenser microphone that has become an industry standard for its smooth, natural sound and remarkable versatility. Featuring an externally polarized (DC bias) true condenser design, the AT4040 utilizes a technically advanced diaphragm tensioned specifically to provide a flat, transparent response with a touch of air in the top end. Its transformerless circuitry virtually eliminates low-frequency distortion, ensuring superior correlation of high-speed transients—making it just as capable of capturing the subtle nuances of a fingerstyle acoustic guitar as it is the power of a screaming vocal.
With an exceptionally low self-noise and a wide dynamic range, this microphone excels in the stringent environments of modern digital recording. It features a switchable 80Hz high-pass filter to roll off unwanted low-end rumble and a -10dB pad for capturing high-SPL sources like drum overheads or dimed guitar cabinets. The symmetrical housing assembly creates an open acoustical environment that minimizes internal reflections, preserving the purity of your sound source.
This unit is in very good condition and has been fully tested in our shop. It delivers the clean, articulate signal these 40-series microphones are famous for. While the chassis shows some typical light cosmetic signs of use from being handled in a studio setting, it remains structurally sound and functionally perfect. If you are looking for a workhorse condenser that consistently punches way above its price point, the AT4040 is an essential addition to any mic locker.
