AKG CHM99 WHITE Hanging Cardioid Condenser Microphone

The AKG CHM99 WHITE is a compact hanging condenser mic engineered for overhead and ambient capture in live sound and installed systems. Its diminutive form factor—just 55mm tall with a 13.5mm diameter—makes it nearly invisible in sight lines while delivering professional cardioid rejection and clean audio output. The included spring steel hanging clamp and 10-meter twist-resistant cable allow for quick deployment in any rigging scenario.

Design & Build

Built to hang discreetly above stages, bars, or meeting spaces, this microphone weighs only 0.7 oz and measures 0.5" × 2.1", minimizing visual obstruction while maintaining structural stability. The package includes a windscreen and purpose-built hanging hardware that secures the mic safely and keeps cable routing clean and organized.

Audio Performance

The cardioid pattern with a 125° pickup angle isolates the mic's target source while rejecting off-axis noise—critical for hanging applications where ambient rejection matters. A 73 dB-A signal-to-noise ratio and 21 dB-A equivalent noise level ensure clear, low-noise capture even in moderately loud venues, while the balanced XLR output integrates seamlessly into any professional audio console or mixing setup.
