NORMA is pleased to present the new REVO DS1 Digital Source. It is an extremely interesting product, both for its outstanding technical content and for its noticeable versatility, obviously combined with the rigor of NORMA musical tradition. In addition to a CD player section that represents the evolution of the REVO CDP1R, the NORMA REVO DS-1 source offers a complete set of digital inputs. As a matter of fact, there is both a full bandwidth USB input (192.0 KHz) as well as 4 SPDIF inputs, coaxial, optical and XLR. Therefore, all the features for an advanced digital source are contained within a single frame, and they are able to meet even the most demanding user’s needs with no limitations, both in terms of versatility as well as of listening quality. The same conversion section and the same output stages that made the REVO CDP1R unique, famous and appreciated, are used in REVO DS-1 enabling it to reach top world production levels as the quality of sound reproduction.
In a historical moment when we witness the proliferation of DACs for “computer music”, exclusively designed around the parameters of the so-called technical modernity and cost reduction to the detriment of the potential sound performance of high resolution devices, NORMA proposes a “universal machine” which is highly sophisticated in all the aspects relevant to sound output. You can finally truly appreciate the actual quality of high resolution files, without the limitations imposed by inadequate implementation. A complete set of NORMA DS-1 enables the user to manage and store all digital parameters independently for each input. For instance, it is possible to enable the over-sampling feature at any frequency as the user wishes as well as disable it if undesired.
It is also possible to select the Master Clock source between the Low-Jitter local oscillator and the input signal’s one. Finally, it is possible to vary the upsampler parameters, the digital filter’s response, the absolute phase and the volume of the output signal. All of this can be carried out both via the local controls as well as by remote control.
