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.
Overhead for Drums / Percussion: Bells, cymbals, hi-hat, goodie table
Acoustic instruments: Guitar, piano, saxophone, orchestra (zone miking)
Group vocals: ADX51 may be used as a hanging mic or on a stand to pick up group vocals for ensemble, choirs or plays. Two mics may be positioned overhead or in front of the group, at a distance of 4-6 feet apart.
