The Audix ADX51 is a professional pre-polarized condenser microphone designed for general instrument and vocal capturing. The cardioid polar pattern eliminates residual noise and feedback at the off-axis sections of the capsule. The ADX51 features a 10 dB pad switch to provide extra headroom while capturing highly transient audio signal. The low-frequency roll-off switch eliminates low-frequency hum, noise and proximity effect. The ADX51 features a low-noise output circuitry and is at home capturing brass, percussion instruments, guitar cabinets, vocals, and much more.
