Soulution 560 D/A-converter

Ingen forstærker eller højttaler kan nogensinde skabe hvad der måtte være tabt i begyndelsen! Kvaliteten ved optagelsen og det indgående signal er fundamentalt i hifi. Soulution 560 D/A-converter lever op til dette, alt hvad som findes i det digitale signal bliver transporteret til analogt, intet slettes og intet tilføjes.

Philosophy

In many areas the 560 D/A-Converter is based on the same proven technical solutions used in the 745 SACD-Player. It also embodies the same principles in its design: top grade digital inter­faces for optimal reception of the music data, a super-precise master clock generator to avoid jitter, intelligent digital signal processing with over­sampling technology, and analogue output stages of top end pre­amplifier quality.

Design

As with its Series 7 sibling the 560 D/A-Converter is packed with cutting-edge tech­nology with one objective – the love of music. The parallels include a consistent dual mono design in the output stages and separate power supplies for digital elec­tronics and the analogue stages. The 560 D/A-Converter adds a digital volume control that allows direct connec­tion to a power amplifier.

Upsampling

Audio data is buffered then upsampled to 24Bit/384kHz. We believe precision of inter­polation is more impor­tant than high clock rates. Our players and D/A converters use an algorithm from the highly regarded Anagram Technologies followed by Burr Brown D/A converters in a digital symmetric configuration. As we consider the PCM conversion technology as superior, the DSD signals get converted before its final D/A conversion.

The 560 D/A-Converter is equipped with soulution’s innovative Zero-Phase-Technology. Smallest timing errors provoked by the analog low pass filter of the D/A converter get eliminated. Every D/A converter requires an analog low pass filter in its output in order to suppress high frequency noise and aliasing signals. The 560’s 3rd order bessel filter, with a cut-off frequency of 120kHz, does show a phase shift of up to 15° in the audio band. Due to the Zero-Phase-Technology the phase error of the analog music signal remains below 1°, 20Hz – 100kHz! The Zero-Phase-Technology brings you even closer to the beauty of the source material! The music gets even more realistic and 3-dimensional with a lot of “air” around instruments and voices. As close to the source as possible! No detail gets lost.

D/A conversion

Burr-Brown devices perform D/A conversion only. Their internal upsampling and filter stages are not used. The output currents are converted to voltage and then filtered. With an internal bandwidth of 40 MHz, this current/voltage conversion stage allows best signal-to-noise performance and maximum dynamics in the analogue domain.

Output stage

The wideband output stage of the 560 D/A-Converter has a bandwidth of 20MHz (-3dB). With such speed of response all musical details are reproduced true to life creating a three-dimensional, spatial sound to bring real listening pleasure.

Operation

The 560 D/A-Converter is operated from front-panel buttons and a rotary control. Further functions can be used to optimise and match an entire audio system around different components.
