What is "channel separation" in the spec of rcd-1072?

thanks.

It is the difference between the left en right channel in decibels. For CD it is about 100db and actually irrelevant, since any CD players can achieve about 96db.

Recordplayers and tape-desck could only get about 25-60db channel seperation.

Do you mean that if the level reaches more than 96db, you can hear the difference between L and R?

thanks.

It's a measuremnent of crosstalk. Theoretically, the left and right channels of a stereo component (or the 5.1 or 7.1 channels in home theater gear) are totally independent of one another. In reality, due to proximity of components within the box, power supply limits, impedance, etc. there will be a small amount of bleed over from one channel to ther other.

For digital devices (CD/DVD players), amplifiers, and processors the channel separation is normally very high (96+ dB). This means there is, for all practical purposes, virtually no crosstalk. For analog signal sources (FM tuners, turntables, tape decks) there tends to be lesser separation, which leads to a reduction in stereo imaging.

Do you mean that if the level reaches more than 96db, you can hear the difference between L and R?

Basically what that means, is if you play something that only plays in the left channel, and you have the volume cranked up to the point where the left channel is playing over 96 dB (and this is LOUD), the right channel will be playing the left channel information at 1 dB (inaudible). In other words, you won't have any discernable crosstalk with that amount of separation.
