Hi

1) I just purchased a SONY RDR-GX380 DVD recorder and notice my DVD Recorder has a setting for a sampling frequency of either 48khz / 16bit or 96khz / 24bit PCM sound output.

Is 96khz a better sound quality than 48khz?

My Sony TV KDL-40S4100 appears to take 96khz and my Pioneer SX-315 Amp does also.

My quesion is though is if the TV and Amp are only desinged for 48khz can these be harmed if the DVD has been set up to output at 96khz?

2) The DVD can output DTS but the TV I am not sure about. Again can the TV be damaged if DTS output is selected from the DVD and the TV does not have a DTS decoder?

3) Also what type of sound output is MPEG requiring a decoder?

Any advise appreciated!

Regards

Blaine

It can be. It is potentially about having twice as many samples of the original sound, so a smoother representation of analogue in digital format.

My Sony TV KDL-40S4100 appears to take 96khz and my Pioneer SX-315 Amp does also.

My quesion is though is if the TV and Amp are only desinged for 48khz can these be harmed if the DVD has been set up to output at 96khz?


No. You will only be outputting those rates through a digital connection. If you're taking the analogue connection out, the Sony will already have done all the digital translation if there is any to be done. The disc you were using would have to have been set up with a 96KHz sampling rate for the magic to be done.

2) The DVD can output DTS but the TV I am not sure about. Again can the TV be damaged if DTS output is selected from the DVD and the TV does not have a DTS decoder?

No. It's pretty much impossible to cause damage by that route. You'll have to resort to a hammer if you really want to hurt the TV.
Again, the decoding will probably be done in the Sony, unless you've got a digital connection to the TV - HDMI, for instance. If you are using a digital connection and send DTS or 96KHz, you'll just get a confused TV, not a broken one, if it's not set up to take it. It might come up with an error message.

3) Also what type of sound output is MPEG requiring a decoder?

From <a href="http://en.wikipedia.org/wiki/MPEG-2">Wikipedia</a> -

'MPEG-2 is a standard for "the generic coding of moving pictures and associated audio information".[1] It describes a combination of lossy video compression and lossy audio data compression methods which permit storage and transmission of movies using currently available storage media and transmission bandwidth.'
