First, let me say that I think the 519 will probably be used by not only Meridian aficionados, but also by owners of other brands who opt to wait for DVD's digital output, and not to support the RF input.

On the 519, you connect the Digital output and the AC-3 output of your LD player into the respective inputs of the 519.

Then you connect the Digital output of the 519 to the input of your digital processor, in my case the 562V controller. The 519 detects the presence of an AC-3 signal, and if so, it sends the AC-3 bit-stream; otherwise it sends the PCM track of your LD (in digital form).

The other function of this little box is to reduce jitter, which most LD players are extremely prone to. It also helps to cut down on the popping that the 565 has been reported to have.

The popping problem is due to the coax out on the LD being turned off instead of being muted when no signal is present. At $695.00, the 519 is a bit expensive, but when you look at what you pay just for some jitter reduction units, it is a super bargain.

If you want to do a side by side comparison of the AC-3 and PCM track, you need to bypass the coax input of the 519, and use a different input on the 562V or surround processor. When the 519 detects the AC-3 bit-stream, it only sends that signal. There are jumpers located inside the unit, but I have not used them.
Once you are through showing all your friends the difference between AC-3 and Pro Logic, plug the coax back into the 519.

The improvement through jitter reduction is nothing short of amazing! The soundstage becomes more refined, and even more subtle nuances are revealed.
