AKG CHM99 WHITE Hanging Cardioid Condenser Microphone
Description
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.

Frequently Asked Questions
What does the hanging clamp do, and what's included in the box?
The spring steel hanging clamp secures the microphone to pipes, trusses, or other rigging points and keeps cable routing organized. The package includes the clamp, a 10-meter twist-resistant XLR cable, and a windscreen to reduce handling and wind noise.
Is this mic suitable for close-miking vocals or instrument amplifiers?
No. The CHM99 is engineered for overhead and ambient capture; it is not designed for close-miked lead vocals or amplifier sources. Its cardioid pattern and pickup characteristics are optimized for hanging applications and room-level recording.
What are the phantom power requirements?
The CHM99 requires 9V to 52V phantom power at 3 mA current draw. Standard console phantom power supplies (typically 48V) will operate it correctly.
How does the cardioid polar pattern help in a live or hanging scenario?
The 125° cardioid pickup angle focuses the microphone's sensitivity on the target source below and rejects off-axis noise from the sides and rear. This isolation is essential when hanging overhead, reducing pickup of crowd noise, reflections, or other unwanted ambient sound.
What is the frequency response, and how does it affect what it captures?
The frequency response spans 70 Hz to 18 kHz, covering the full range of speech, drums, and most instruments. The 21 dB-A equivalent noise level and 73 dB-A signal-to-noise ratio ensure clean capture even in moderately loud environments.
