There are many different ways this item can be used in your system/mastering studio/etc. Please see the manual linked below for full details.

More from a Stereophile review written by John Atkinson:

"The 518 is a successor to Meridian's 618 Mastering Processor, which has gained no small reputation in professional audio circles for the way it reduces 20-bit audio data to the 16 mandated by the CD standard without sacrificing sound quality. It adds considerable functionality, however, and in its most fundamental role can be used as a digital replacement for a system's conventional preamplifier, accepting the outputs of digital sources, allowing for volume control, and feeding its output either to a D/A processor/amplifier/speaker combination, or to a system based on Meridian's DSP-series powered loudspeakers, which have digital data inputs. (Bob Stuart: "At Meridian, we say there is no preamp like no preamp!")

Or it can be used like the 618: to make 16-bit recordings with resolution and sound quality approaching those of true 18- or 20-bit recordings.

Or it can be used as a sophisticated jitter-reduction unit that also allows the user to increase resolution, change the gain of the digital signal, and even to add or remove pre-emphasis."
