Sony NS3100, DVP-NS9100ES manual Sync, Separate speaker settings, Super Audio D/A Converter SA DAC

Incidentally, this adjustment is not duplicated on most A/V receivers. Some receivers can adjust for speaker distance on the multi-channel signals that are decoded in the receiver itself. But most receivers offer no such adjustment for the 5.1-channel analog inputs you may be using to enjoy multi-channel Super Audio CD.

A/V Sync

Today's advanced televisions and video projectors often incorporate sophisticated video signal processing to optimize the image quality. Often, these circuits require buffer memories that result in a slight delay of the video signal. Unfortunately, this can result in a mismatch, where the television picture lags behind the sound from the speakers by some fraction of a second. As you can imagine, the effect can be unnatural and annoying.

That's why Sony offers another Digital Signal Processing function: AV Sync. This enables you to correct time misalignments between the audio and video signals by up to 120 milliseconds, in 10 millisecond increments. Sony brings your television and your home theater speakers back into alignment. A/V Sync achieves identical results on stereo, 5.1-channel and even digital audio outputs.

Separate speaker settings

Unlike previous models, the DVP-NS9100ES and NS3100 also provide speaker size and location settings for Super Audio CD playback that are separate from the settings you make for DVD-Video and other formats.

Super Audio D/A Converter (SA DAC)

If you're using the DVP-NS9100ES with an amplifier that does not have an i.LINK® interface of if you're enjoying the NS3100ES, you won't be listening to Super Audio CDs via digital output. In this case, the player's on-board D/A converters will exert a pivotal influence on sound quality.

Multi-channel Super Audio CDs present the player with six separate channels—all recorded with exactly the same superb quality as two-channel Super Audio CD. That's why the Sony® ES Series DVD players incorporate six channels of Sony's Super Audio D/A Converter (SA DAC). The circuit delivers superlative performance for multi-channel SA-CD, two-channel SA-CD and CD reproduction.
