The ADX-20i is a pre-polarized condenser microphone designed to handle a wide variety of clip-on applications. The ADX20i is sonically superior as well as aesthetically pleasing and is ideally suited for saxophone, trombone, trumpet and other brass instruments. With a smooth uniform response over a frequency range of40 Hz – 20 kHz, the ADX-20i provides a rich, warm sound not typical of microphones this size. It is machined from solid brass and has a low reflective black e-coat finish. The ADX-20i operates on phantom power (9-52 volts) with the preamp module provided (APS-910). It may be used in battery mode with optional phantom power adapter (APS-911). The ADX-20i can be utilized with a wireless system. Depending on the brand of wireless and the connector configuration of the instrument body pack, the ADX-20i connector would need to be modified accordingly. Low noise electronic circuitry, and balanced low impedanceoutput allow for interference free performance even with long cable runs.Features:High tension spring clamp keeps mic in placeMulti-position gooseneckHighly accurate sound reproductionAvailable in hypercardeoid version (ADX-20i/hc)Specifications:
