Emerson Digital Streaming Interface

Its AES/EBU and S/PDIF outputs allow a connection to any system equipped with digital audio input.

The Emerson DIGITAL model becomes the ideal companion to a High-End digital-to-analog converter that does not have a network connection.



Technology, precision and quality

The original format of the digital Hi-Res music tracks provided by streaming services must be maintained.

With this in mind, we perform no alterations or conversions in order to fully respect data integrity. The streamed music is fully “bit-perfect” all the way through.

We have added extremely precise clocks which ensure perfect timing of data flow, “jitter-free”  from the network playback through to the output signals.

An effective line

With a radical and compact design, carved from massive aluminum, protected by powder coating, both models of the Emerson range remain discreet wherever you install them.

The Emerson in action

The Emerson DIGITAL can be integrated into a multitude of different configurations.
