The Audio-Technica AT4050 Multi-Pattern Studio Condenser Microphone is a professional side-address condenser designed to capture every nuance of a performance. This large-diaphragm microphone combines high-SPL capability with transparent upper and mid frequencies, complemented by rich low-end qualities. It serves as a versatile tool for both critical studio recording and demanding live sound productions.
The AT4050 features three switchable polar patterns: omni, cardioid, and figure-of-eight. A dual-diaphragm capsule design ensures the microphone maintains precise polar pattern definition across the entire frequency range. This flexibility allows users to adapt the microphone to various recording environments and sound sources effectively.
Audio-Technica utilizes dual 2-micron-thick, vapor-deposited gold diaphragms that undergo a five-step aging process to ensure performance characteristics remain constant over years of use. A precision-machined, nickel-plated brass acoustic element baffle provides rock-solid stability and exceptional sensitivity. The internal transformerless circuitry virtually eliminates low-frequency distortion while providing superior correlation of high-speed transients.
State-of-the-art surface-mount electronics ensure compliance with stringent consistency and reliability standards. The AT4050 includes a switchable 80 Hz hi-pass filter and a 10 dB pad to manage high-output sources and low-frequency noise. For enhanced recording clarity, a custom shock mount provides superior isolation from mechanical vibrations.
