Mini DAC makes high resolution audio simple. There are no processors, touch screens, or software updates. Mini DAC is an upsampler that converts lower resolution digital music to high resolution. It does this by re-clocking the data and converting it to 24 bit 96kHz. The result is a more musical experience than the USB streaming, mp3, or CDs source.
Mini DAC has a single optical and USB input. Changes to the user interface and battery power allows the full scale DAC design to fit into a smaller case. The minimalist interface consists of a single toggle switch to select between USB and Optical input, a 3.5mm output jack, and acrylic face plates. Volume is fixed at line level. The money is spent on providing the same DAC and power regulation circuitry as in our custom products.
The plot to the left shows the harmonics and noise levels of the Mini DAC and ADC combined. Injecting the maximum signal into the system resulted in .002% added distortion to the original signal. Fiber optic was used to connect between the ADC and DAC.
The small size of the Mini DAC allows it to fit in a pocket or on a cramped shelf. The 10.5 hour battery life provides hours of listening pleasure without the need for expensive power cords or conditioners.
The Mini DAC comes standard with acrylic plates. Add $50 for milled aluminum plates and a grounding post.
