Soulution 560 D/A converter

No deletions at the source are mandatory. This holds even more true for the playback of high-resolution files than it did for CDs and SACDs. No amplifier or loud­speaker can make good for what has been lost at the source. The quality of the recording and the signal supplier are of fundamental importance in high fidelity.

The 560 D/A-Converter excels at exactly this task. It captures all digital music data and transports it in the analog domain. No deletions, no additions!

Highlights

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 analog 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 analog stages. The 560 D/A-Converter adds a digital volume control that allows direct connec­tion to a power amplifier.

Upsampling
Audio data is buffered and then upsampled to 24Bit/384kHz. We believe the 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.

zeroφtech
The 560 D/A-Converter is equipped with solutions innovative Zero-Phase-Technology. The 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 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 much “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 the best signal-to-noise performance and maximum dynamics in the analog 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.
