The CM311 reference head-worn condenser microphone is designed for touring and live-sound applications. It sounds like the best handheld microphones - full, clear and distortion-free, even with the loudest singers.

Differoid® stands for differential cardioid, which cancels ambient noise from floor monitors, crowds and other sources. Controlled field tests show that the Differoid provides up to 12dB more gain before feedback than conventional cardioid microphones. Many users of CM311 say that their house mix is better because the mic's isolation is nearly complete.

The CM-311 L is terminated with a female professional mini-XLR connector for use with all AKG wireless body-pack transmitters. The microphone comes with a custom molded hard plastic case.

Differoid noise-cancelling technology
for highest ambient noise rejection

Cardioid polar pattern
for outstanding gain before feedback

Condenser capsule with internal shock mount
for efficient rejection of mechanical and body noise

Robust headband construction
for maximum comfort and freedom of movement

The DGN99 and DGN99 E are dynamic gooseneck microphones with cardioid polar pattern for general public address and communication use. The microphones provide a frequency response tailored for optimum intelligibility, good off-axis rejection for high gain before feedback and suppression of unwanted ambient noise. The all-metal body ensures a long, useful life for the microphone even in tough day-to-day use. The DGN99 E comes with an integrated XLR connector while the DGN99 offers open cables for universal use. Using a dynamic capsule, the microphones do not require any powering.

The DST99 S is a paging microphone with cardioid polar pattern for general public address and communication use. The DST99 S provides a frequency response tailored to speech use, for optimum intelligibility as well as good off-axis rejection, high gain before feedback and suppression of unwanted ambient noise. The all-metal body ensures a long useful life for the microphone, even in tough day-to-day use.

The DST99 S is mounted on a table stand with an on/off switch and supplies a coiled cable with three-pin XLR connector. Using a dynamic capsule, the DST99 S does not require any powering.
