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!

Portable USB-DAC and headphone amplifier DA-10 provides Denon's audio performance on par with top sound systems of separate devices in a compact size and equipped with high-capacity rechargeable lithium-ion battery of 3200 mAh, for many hours listening pleasure anywhere, even on the road.

Excellent audio performance from your digital music sources
With many mobile devices, headphone amplifier section is mostly designed for low power consumption for extending battery life. While this is satisfactory with normal headphones with top type headphones, the sound performance suffers.
The DA-10 features advanced analog output stage, with the possibility of treatment of a very wide range of types of headphones, including top type models headset and studio-quality headphones, which are often high impedance and require more power than the output stage.
A mounted sideways gain switch allows you to adjust the gain of the output stage for a perfect combination with your favorite top headphones, including high impedance models, and the final analog output module has a separate power cache circuit for perfect listening experience. There is also the possibility steady output for connection to an external audio system.

High quality audio technologies
Located in an elegant aluminum chassis with solid volume slider aluminum alloy, the DA-10 is equipped with Denon's exclusive technologies for superior music listening experience. With the most sophisticated converting digital signal to analog, the DA-10 is equipped with a heading reference Burr-Brown PCM-1795 32-bit high resolution DAC chip, that can treat multiple sampling frequencies up to 192 kHz, and bit depths up 24 bits. The DA-10 can also decode high-resolution DSD audio tracks (the type found on SACDs), and has the ability to decode DSD files 2.8 and 5.6 MHz.
The AL32 proprietary technology Denon using our inventive DSP digital filtering, sampling upwardly and processing algorithms for converting upwardly and patterning high-resolution digital audio noise at 32 bits, providing drastically improved low-level details and disappearance deformation.

Design Net for music lovers
Equipped with Class Reference Burr-Brown PCM-1795 DAC chip, the DA-10 has a leading manufacture for music lovers, including dual master clock crystals, each optimized for specific sampling frequencies and located right next to the DAC chip on the sound board for maximum reduction in distortion.
