4 channel dsp d/a converter and network renderer
February 2025 - now updated to the MKII 4-CHANNEL VERSION. Your older version CAN be updated to the MKII version. Call us for details!
Info on the new version:
What is the purpose of the -4ch versions?
The -4ch versions use one of the latest DAC chips with stellar technical specifications. So the -4ch versions make for an enhanced 2 channel DAC, with the same features as the DAC501 / DAC502 units sport. The sonic characteristics of the -4ch versions are on a higher level with incredible transparency and openness. Both line output stages and headphone output stages are built with discrete electronics similar to the standard DAC50x.
All standard DAC50x units can be upgraded with the -4ch version. It is a new analog section module to be installed in the unit plus a new software needs to be loaded. It is our goal to keep our equipment upgradeable for long-term securing of your investment. The standard DAC501 / DAC502 units we continue to manufacture. In addition the -4ch versions will be capable to play 4 channels simultaneously once we introduce the
necessary software.
What technology is used?
The DAC501-4ch and DAC502-4ch units are based on the following hardware parts:
ARM processor for Network and USB interfacing and general control of the unit
SHARC Signal Processor chip for various signal processing tasks including sampling frequency conversion and high precision volume control
Extensive power supply with separate power transformers and many high precision voltage regulators
Local, very low jitter clock generator for the D/A converter
State of the art D/A conversion
Discrete analog sections following the D/A conversion
Very low impedance outputs
Analog output level selection to accommodate for amplifiers and headphones
Some technical specifications:
Signal to Noise Ratio: Better than 128dB
Signal to Distortion and Noise Ratio: Better than 115dB
Linearity: Within a 120dB range less than +-0.2dB deviation from ideal
Spurious components including harmonics: Less than -120dB
Crosstalk between channels: Less than -110dB, 20Hz up to 20kHz
