The Audix ADX20iP Miniature Condenser Instrument Microphone is a professional clip-on microphone designed to capture saxophones, brass instruments, and other acoustic instruments with natural detail and excellent isolation. Its compact condenser capsule, cardioid polar pattern, and flexible mounting system make it well suited for live performances, studio recording, and professional sound reinforcement.
Designed, assembled, and tested by Audix in the USA, the ADX20iP delivers accurate sound reproduction across a wide 40Hz–20kHz frequency range. Its directional pickup pattern helps reduce unwanted stage noise and microphone feedback while maintaining the clarity and transient response needed for close-miking instruments.
The ADX20iP includes the Audix MC20i spring-tension instrument clip, allowing the microphone to attach directly to the bell of a saxophone or compatible brass instrument. An integrated rubber shock-mount system helps isolate the microphone capsule from instrument vibration and handling noise.
Unlike the wireless-oriented ADX20i version, the ADX20iP is configured for wired microphone applications and includes the Audix APS910 phantom power adapter. The package also includes a 6-foot microphone cable and protective carrying pouch, providing a convenient solution for musicians, recording engineers, and live sound professionals.
Features and Benefits
Miniature Condenser Capsule for Natural Instrument Sound
The ADX20iP uses a pre-polarized condenser capsule designed to capture the detail, articulation, and dynamics of acoustic instruments.
Its 40Hz–20kHz frequency response makes it suitable for reproducing the tonal characteristics of saxophones, brass instruments, and other acoustic sound sources.
The miniature capsule allows close placement without the bulk of a traditional instrument microphone.
Cardioid Polar Pattern for Improved Isolation
The ADX20iP features a cardioid pickup pattern that focuses on sound arriving from the front of the microphone while reducing unwanted sound from behind it.
This directional response helps isolate the instrument from nearby stage monitors, amplifiers, and other performers.
Proper microphone placement can also help improve gain before feedback in live sound environments.
Designed for Saxophones and Brass Instruments
The ADX20iP is particularly well suited for saxophones, trumpets, trombones, and other brass instruments.
Its compact design allows the microphone to remain close to the instrument while minimizing interference with the musician's performance.
The flexible gooseneck mounting arrangement makes it easy to adjust capsule placement for the desired tonal balance.
Included MC20i Spring-Tension Instrument Clip
The supplied Audix MC20i clip features a spring-tension design that attaches to compatible instrument bells.
This allows musicians to position the microphone directly on the instrument without relying on a floor-standing microphone stand.
The clip-on configuration is especially useful for performers who move around the stage.
Rubber Shock-Mount System
The microphone capsule is supported by a rubber isolation system that helps reduce mechanical vibration transferred through the instrument and mounting hardware.
This design minimizes unwanted contact and handling noise during live performances and recording sessions.
Handles High Sound Pressure Levels
With a maximum sound pressure handling capability of at least 135dB SPL, the ADX20iP is suitable for close-miking loud acoustic instruments.
This provides flexibility for capturing powerful brass performances without requiring the microphone to be positioned far from the sound source.
Included APS910 Phantom Power Adapter
The ADX20iP package includes the Audix APS910 adapter for connecting the microphone to compatible professional audio equipment.
This allows the microphone to be used with a standard XLR microphone input and a suitable phantom power source.
The wired configuration is useful for recording studios, live sound consoles, and fixed audio installations.
Lightweight and Compact Construction
The miniature microphone features a machined brass capsule housing with a black finish.
Its compact size and lightweight construction help maintain a discreet appearance while allowing flexible instrument positioning.
Flexible Applications Beyond Brass Instruments
Although designed primarily for saxophones and brass instruments, the ADX20iP can also be used for other acoustic instruments when mounted and positioned appropriately.
With optional mounting accessories, it can be adapted for recording applications involving strings, accordion, and other sound sources.

Need a Compatible Microphone Cable or Mounting Accessory?
The Audix ADX20iP includes the MC20i instrument clip, APS910 phantom power adapter, 6-foot microphone cable, and carrying pouch.
For wired operation, connect the APS910 adapter to a compatible professional microphone input using a balanced XLR cable and provide the required phantom power.
Additional mounting accessories may be used when the microphone needs to be positioned on a stand rather than attached directly to an instrument.
Important: The ADX20iP is the wired version. For compatible Audix wireless systems, verify the appropriate ADX20i microphone version and connector before ordering.
