Legendary AKG sound. Brilliant sound and ease of use. Unique HDAP (High Definition Audio Performance) technology ensures the best possible, realistic sound at any time. The rugged handheld transmitter with its soft-touch finish is extremely easy to use and fulfills the highest esthetic requirements. The transmitters operate for 30 hours off a single AA size battery, saving frequent battery replacements and thus money.
The D 880 WL 1 capsule is becoming the new standard microphone for lead and backing vocals on stage. Never before has it been possible to produce a diaphragm with differentiating thicknesses. The Varimotion process allows the adjustment to take place at the diaphragm. The result is a quantum leap in sound performance. The Doubleflex anti-vibration system reduces all kinds of interference.
