The German audio company beyerdynamic will debut a new aviation headset at this year’s EAA AirVenture in Oshkosh. The HS 800 Digital uses a newly developed DANR (Digital Adaptive Noise Reduction) which combines the advantages of feed-back and feed-forward ANR for the first time in a digital system, according to company officials.
ANR headsets use conventional analogue feed-back filter, because these suppress wideband interference signals with high reaction speed, company officials said, noting system-related disadvantages, such as the background noise and the limited capacity for complex sound,s were accepted in the market. Feed-forward digital control was introduced by the beyerdynamic HS 600 DANR. The HS 800 Digital combines feed-back and feed-forward ANR.
The HS 800 Digital is available in three versions. In addition to the version with the two standard jack plugs, there is the HS 800 Digital Rotor with spiral cable and U-174/U jack plug for helicopters. The HS 800 Digital 6pin has a six pin Lemo connector, which — beside the microphone and stereo headphones signal — provides the electrical system voltage to get along without batteries.
Recommended retail price: $839.
