Using state-of-the-art Audio Precision testing equipment, no jitter-induced artifacts can be detected with the DAC1 or the DAC1 USB. This clock-recovery topology outperforms even the most well-designed two-stage PLL designs. With the UltraLock™ clock-recovery system, the digital-to-analog conversion-clock in the DAC1 and DAC1 USB is totally isolated from the clock of the digital audio input. Jitter is NOT a problem for the DAC1 and DAC1 USB, which achieve jitter immunity by utilizing the proprietary UltraLock™ clock-recovery system. Many modern (and expensive) converters suffer from severe jitter-induced distortion. The result of these misfires is a non-musical, digital distortion. Jitter is a type of clock error that, if not properly addressed, can cause the D-to-A to misfire. Jitter presents a major problem to most D-to-A converters. Jitter-Immune UltraLock™ĭigital interconnect cables, electro-magnetic interference, and many other variables introduce jitter into the digital audio. Audiophiles have also discovered the smooth and detailed sound of the DAC1, and it has become a centerpiece in may home listening rooms.
