Auzentech Solves Static Issue on Older-Model Denon AV Receivers; Offers Firmware Updates


Auzentech ( is pleased to announced that it has found a solution to problems of audio static when the Auzen X-Fi HomeTheater HD is connected to older-model Denon AV Receivers. A firmware update to the X-Fi HomeTheater HD Sound Card has been created to correct the problem.




As first reported in a September 4 Open Letter from Auzentech, Denon AV Receivers manufactured in early 2008 or before may produce static during playback of high definition bitstream audio with the Auzen X-Fi HomeTheater HD sound card. Although Denon did not respond to Auzentech's attempts to communicate about the problem, we located and purchased some earlier Denon receivers for analysis, and were successful in diagnosing the trouble.




Auzentech engineers found that earlier Denon receivers read HDMI audio sources differently than do newer models, or other receivers on the market. We do not know why the older units were designed to perform differently. However, you should not experience this problem if you own a more recently manufactured Denon receiver or a different brand of receiver.




To adapt the Auzen X-Fi HomeTheater HD to the unique HDMI implementation on Denon's older receivers, Auzentech will apply an X-Fi HomeTheater HD firmware update for anyone affected by the problem. The update will be performed by Auzentech or an authorized Auzentech dealer or technician. If you are an owner of the Auzen X-Fi HomeTheater HD and an older model receiver exhibiting audio static during high definition bitstream audio, please email Auzentech at the address listed below. We will provide guidance on how to update your product.

This firmware update offer includes shipping to and from Auzentech or its representatives.

Auzen X-Fi HomeTheater HD sound cards shipped directly to customers from the Auzentech online store after October 19, 2009 will already have the firmware update applied. Models purchased in retail stores may have the original firmware, but are eligible for the update.
