Micro DAC is a USB digital-to-analog (DAC) converter with two outputs, one analog and one digital (optical). Itʼs ideal for converting the audio from your computer into a high-quality analog format without needing to carry anything larger than a flash drive. The sound quality available from the typical headphone jack on a portable device or coming from the standard-issue soundcard found in virtually every computer leaves a lot to be desired. Micro DAC delivers a marked upgrade in sound quality, compared to just plugging your headphones directly into your unitʼs headphone jack.
Use the 1/8-inch analog output to connect any headphones, and enjoy vibrant high-fidelity sound. There is a gain switch that boosts the signal level, so you can drive even high-impedance headphones to a robust loudness level. And since virtually all high-quality audio equipment has an optical digital input, Micro DACʼs optical digital output is perfect for driving that equipment with a pure digital signal—especially valuable since most computers do not have a digital output.
Micro DAC has a rugged aluminum housing and is USB-bus-powered. Getting professional-quality audio from your computer couldnʼt be easier!
