Caution:

Do not switch power off and on rapidly, as this interrupts the normal power-up sequence. We advise waiting at least five seconds between power cycles.

2. Digital Outputs

These outputs provide digital audio signal (DAS) via cables equipped with either XLR-type or RCA-type connectors to a digital audio processor.

The XLR output conforms to the Audio Engineering Society/ European Broadcast Union (AES/EBU) professional digital audio standard, which calls for a 110Ω transmission of the DAS. Use a digital interconnecting cable specifically designed for the 110Ω AES/EBU standard when using this input, with pin assignments as indicated below:

Pin 1: Signal ground

Pin 2: Signal + (non-inverting)

Pin 3: Signal – (inverting)

Connector ground lug: chassis ground

It has been Mark Levinson’s experience that the AES/EBU

interconnection standard offers the best quality of all digital transmission interfaces when fully optimized, and we recommend its use wherever possible between Mark Levinson components.

However, optimizing any electrical digital interface completely represents a significant engineering challenge. It is entirely possible that a different type of input may actually outperform a less-than optimized AES/EBU implementation on some brands of digital components. For this reason, we have gone to great lengths to fully optimize both of the digital outputs on the Nº390S. If you are using your Nº390S with a different brand of processor, we recommend experimenting to determine which type of input on that component results in the best audible performance.

The RCA output provides digital audio signal (DAS) via cables equipped with RCA-type connectors to the digital processor. It conforms to the Sony/Phillips Digital Interface Standard (S/PDIF), which calls for a 75Ω transmission of the DAS. Use a digital interconnecting cable specifically designed for the 75Ω S/PDIF standard when using this output.
