The Nº30.6 Reference Digital Processor sets the standard in the way that digital information is handled. For those who want the finest digital performance today and a solid foundation for the future, the Nº30.6 is among the safest investments it is possible to make. One of the advantages of a separate digital audio processor is that you can take the money which might have otherwise been spent on several built-in D/A converters and put it into one, superior processor which will enhance the performance of all the transports with which it is used. Ironically, many outboard processors fail to live up to this potential due to interference between their various digital inputs. The Nº30.6 provides outstanding isolation between its inputs, realizing the full potential of the various digital transports with which it is used. In fact, every source has its own dedicated digital interface receiver. As a result, the selected input effectively has the Nº30.6 “all to itself ” for its conversion to analog. The Nº30.6 is fully balanced in both the analog and digital domains. All digital filtering and processing is implemented in a balanced configuration, and conversion to analog is accomplished in two opposing polarity 24-bit converters per channel. This approach maintains the integrity of the signal, reducing the opportunities for music-destroying noise and digital artifacts to enter the signal path. See the Nº30.6 owner's manual for instructions on connecting the Nº30.6 with the PLS-330 power supply.
