- Excellent comfort
- Insensitive to moisture, perspiration, and salts
- Dual-diaphragm transducer for cable noise suppression
- Compatible with all standard wireless systems
The new AKG HC 577 L has been designed to be invisible in the limelight. It is so small it will virtually disappear on stage or on camera, while providing perfect mobility and pristine audio quality.
A patented body design protects the microphone's dual-diaphragm transducer from moisture and perspiration. Mechanical noise, cable noise, etc. are reduced to a minimum. The microphone uses a CK 77 omnidirectional transducer that has been an industry standard for lavalier capsules for years and ensures superior audio performance.
The HC 577 L uses dual-ear temple pieces for extreme stability and optimum comfort.

The microphone shall be an extremely light head-worn design. The microphone shall use a dual-diaphragm transducer with a frequency-independent omnidirectional polar pattern. The transducer element shall be protected from penetrating water, sweat and make-up. An additional moisture shield shall protect the transducer element from water, perspiration and makeup flowing along the microphone arm. The length of the neck-back is adjustible. The microphone boom can be mounted left or right-sided. The length of the microphone boom is adjustable. The microphone shall be available in matte skincolor and meet the following performance criteria: frequency response: 20 to 20,000 Hz, The included Presence Boost cap adds 3dB at approx. 12kHz. sensitivity: 8 mV/Pa (-42dBV), electrical impedance: =<3,500 ohms, equivalent noise level (CCIR 468-3) 37dB, max. SPL(k=1%) 133 dB, power requirement: 1.5 to 12 VDC. The microphone shall be fitted with a 1.5 m (5 ft.) cable and its net (exclusive of the cable)/shipping weight shall be 28/150 grams (0.99/5.29 oz.). Available versions: HC 577 L with Mini-XLR connector for AKG wireless pocket receivers, foam and metal screen windscreens in several colors are also available.
