Audix ADX51 Condenser Microphone

The ADX51 is a pre-polarized condenser microphone designed to handle a wide variety of live, studio and broadcast applications. Characterized with a cardioid pickup pattern and a smooth uniform response over a frequency range of 40-20k Hz, the ADX51 is precision machined from solid brass with a low reflective black e-coat finish.

The ADX51 is designed with low noise electronic circuitry, balanced output, and switches that enable a 10 dB pad and a bass roll-off. The ADX51 is road-worthy and capable of handling high sound pressure levels of 142dB.
