Audix ADX18 - Gooseneck Condenser Microphone for Podium and Conferences (45 cm)
The Audix ADX18 is a professional pre-polarized condenser microphone designed to meet the most demanding requirements for fixed installations and live speeches. Known for its reliability and superior sound quality, this model stands out in the market for its ability to capture the human voice with exceptional clarity and naturalness, even at comfortable distances for the speaker. Its 45 cm (approximately 18-inch) gooseneck design provides the ideal length for standard-sized podiums, allowing the microphone to rise above the height of laptops or documents without obstructing the speaker's view.
At the heart of the ADX18 is a highly sensitive (16 mV/Pascal) condenser capsule with a uniformly controlled cardioid polar pattern. This design is crucial for acoustically complex environments, as it effectively isolates the speaker's voice from ambient room noise and other sounds coming from the sides or rear. Thanks to its excellent off-axis rejection (greater than 15 dB), the microphone offers high gain before feedback, making it a reliable and powerful tool for sound engineers and AV system operators.
The ADX18's construction reflects Audix's high engineering standards. Made with a precision-machined brass body and finished in a sleek, non-reflective matte black, this microphone is discreet on camera and extremely durable. Its circuit design includes a preamp integrated into the XLR base, simplifying connection and ensuring a clean, interference-free signal. Furthermore, its extended frequency response of 40 Hz to 18 kHz ensures faithful reproduction of all vocal nuances, delivering a warm, rich sound that enhances intelligibility in conferences, sermons, and corporate presentations.

Frequently Asked Questions
-
Does this microphone need power?
Yes, being a condenser microphone, the ADX18 requires phantom power (18-52V) to function properly.
-
How do you install it on a table?
The product includes the TM1218 flange mount, which allows you to permanently attach the microphone to a flat surface. It is also compatible with anti-vibration desktop stands (not included) if you prefer not to drill into the surface.
-
Is it compatible with wireless systems?
The ADX18 is a wired microphone with an XLR connection. To make it wireless, you would need to connect it to a plug-on transmitter compatible with phantom power, although its primary use is wired.
-
What does "off-axis attenuation" mean?
This means the microphone rejects sounds that don't come directly from the front (in this case, by more than 15 dB), which helps ensure that only your voice is heard and not echoes from the room or nearby speakers.
