Audio formats

There are some audio formats recorded on discs as shown below.

•Linear PCM

Uncompressed digital audio, the same format used on CDs and most studio masters.

DVD VIDEO supports 2 channels at sampling rates of 48/96 kHz and quantization of 16/20/24 bits.

Audio CD/Video CD is limited to 2 channels, 44.1 kHz at 16 bits.

•Dolby Digital

A surround audio format configured with six channels. Because the "LFE (Low-Frequency Effect for sub-woofer, etc.)" channel, one of the six channels, is an auxiliary channel, this format is called "5.1-channel system".

Not all Dolby Digital discs contain six (5.1) channel information.

•DTS (Digital Theater Systems)

A surround audio format configured with six (5.1) channels which is same as Dolby Digital. Because the compression ratio is lower than Dolby Digital, it provides wider dynamic range and better separation. Not all DTS discs contain six (5.1) channel information.

The associated indicator lights up in the display window when playing back a disc.

Indicator	Audio format

LPCM	Linear PCM

DOLBY DIGITAL	Dolby Digital

DTS	DTS (Digital Theater Systems)

Note that, with some formats and/or depending on the unit's "DIGITAL AUDIO OUTPUT" setting, digital audio signals are not always output from the unit's DIGITAL OUT jacks as are recorded on the disc.
