The Audix ADX12 and ADX18 Miniature Gooseneck Condenser Microphones provide clear, natural speech reproduction for podiums, lecterns, conference rooms, houses of worship, and professional presentation systems. Available in 12-inch and 18-inch gooseneck configurations with cardioid or hypercardioid pickup patterns, these microphones offer flexible solutions for both permanent installations and portable speaking applications.
Designed to capture speech from a comfortable distance, the ADX12 and ADX18 feature precision-engineered condenser capsules, low-noise electronics, and a wide 40Hz–18kHz frequency response. Their directional pickup patterns help reduce unwanted room noise while maintaining accurate voice reproduction for meetings, presentations, and public address systems.
Each microphone features dual flexible gooseneck sections for precise positioning, an integrated microphone preamplifier housed in the XLR base, and a non-reflective black finish. The interchangeable capsule design and multiple mounting options make the ADX Series a practical choice for commercial AV installations.
Whether installed permanently in a lectern or used with a compatible tabletop microphone base, the Audix ADX12 and ADX18 combine professional speech intelligibility with a discreet, durable design.
Features and Benefits
Natural, Accurate Speech Reproduction
The ADX12 and ADX18 use pre-polarized condenser technology to reproduce spoken voice with clarity and detail.
Their 40Hz–18kHz frequency response provides natural sound reproduction for speeches, presentations, conference discussions, and other spoken-word applications.
Cardioid and Hypercardioid Pickup Options
Choose the polar pattern best suited to your installation.
Cardioid Models – ADX12 and ADX18
Cardioid pickup emphasizes sound arriving from the front while reducing sound from the rear. This makes these models suitable for podiums, conference rooms, and general speech reinforcement.
Hypercardioid Models – ADX12HC and ADX18HC
Hypercardioid pickup provides a narrower front pickup area for more focused sound capture. These models are useful when additional rejection of sound arriving from the sides is needed, although microphone positioning remains important because hypercardioid microphones have a small rear pickup lobe.
Two Gooseneck Lengths for Flexible Installation
The Audix ADX Series is available in two lengths to accommodate different podium heights, tabletop arrangements, and speaker preferences.
- ADX12: 12-inch nominal gooseneck, approximately 16 inches overall
- ADX18: 18-inch nominal gooseneck, approximately 22 inches overall
The shorter ADX12 is well suited for compact lecterns and tabletop installations, while the longer ADX18 provides additional reach for taller podiums and larger presentation surfaces.
Dual Flexible Gooseneck Sections
Flexible sections near the microphone head and base allow precise adjustment of microphone placement.
This helps installers and presenters position the microphone toward the speaker's mouth without requiring a bulky external microphone arm.
Integrated XLR Microphone Preamplifier
The ADX12 and ADX18 feature integrated preamplifier circuitry built into the microphone's XLR base.
This compact design allows the microphone to connect directly to compatible professional microphone inputs through a standard XLR connection.
Interchangeable Microphone Capsule
The modular capsule design allows compatible cardioid and hypercardioid capsules to be replaced when needed.
This provides flexibility for maintenance and changing installation requirements without replacing the entire microphone assembly.
Multiple Mounting Options
Each microphone includes a flange mount for permanent installation on a podium, lectern, or tabletop.
For additional flexibility, the microphones can also be used with compatible Audix ATS Series tabletop stands or a standard microphone stand with the appropriate adapter.
An optional shock-isolated flange mount can help reduce vibration transmitted through the mounting surface.
Low-Profile Professional Appearance
The slender gooseneck design and matte black finish help the ADX12 and ADX18 blend into professional presentation environments.
Their non-reflective appearance is especially useful for video production, conference rooms, worship facilities, and presentation spaces.
Professional Phantom Power Operation
Both models require 18–52V phantom power and feature a standard 3-pin male XLR connection.
They are designed for use with professional mixers, DSP systems, and microphone preamplifiers that provide compatible phantom power.
