Default Re: Toshiba HD XA2 True HD Audio

Hi from Bob at PureLink. The HS-42A is capable of extracting the HD Audio content from the HDMI signal. The level of resolution is determined by the player and the software. The switcher does not care, it just passes it along.

The Dolby TruHD and DTS Master HD soundtracks, found exclusively on HD-DVD and Blu-ray discs, and only accessible via the HDMI connection, are the non-compressed audio content. However, not all players are capable yet of decoding this bit stream because their not powerful enough. When this happens, the player automatically defaults to the next highest resolution content, which is the LPCM 5.1 channel version. This content is better than Dolby Digital Plus or DTS Neo-6 on DVD, with more dynamic range than a regular DVD but not as much as we will hear when the players or receivers show up with enough computing power to actually decode the new audio codecs with no compression.

Hope this helps. The HS-42A is capable of taking that audio content and routing it to your current receiver or preamp digital audio input with one coaxial or toslink cable.
