About: Audix ADX20i Wireless Component Condenser Instrument Microphone

Designed, assembled and tested by Audix in the USA, the ADX20i is a miniaturized condenser microphone used for professional stage and studio applications. The ADX20i is known for its clarity, excellent transient response, resistance to feedback, SPL handling and ease of operation. The ADX20i is primarily used for miking saxophone and other brass instruments.

The ADX20i is characterized with a uniformly controlled cardioid polar pattern. This provides excellent isolation and feedback control on stage as well as natural sound reproduction at very close distances.

With a smooth and accurate response over a frequency range of 40 Hz - 20 kHz, the ADX20i is lightweight, compact and simple to use. Housed in an aluminum ring and isolated by means of a rubber shock mount system, the ADX20i comes with a spring tension gooseneck clip (MC20i) for easy mounting to the bell of an instrument. A number of optional accessories are available, which allows for the ADX20i to be used on a microphone stand for a wider variety of applications.

The ADX20i is designed for use with Audix wireless systems. The ADX20iP is designed for use with a standard microphone cable. The ADX20iP operates on phantom voltage of 5-52 Volts and is supplied with a phantom power adapter (APS910), 6’ integrated microphone cable, gooseneck clip (MC20i) and carrying pouch.
