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. The digital section features asynchronous treatment USB signal for maximum stability and sound quality, and the DA-10 is equipped with the exclusive Denon AL32 advanced DSP digital filtering and shaping-noise, providing the highest resolution possible with current HD tracks.
There are separate circuit cards for digital audio portion and the power portion for avoiding interference between the steps, and the portion of the D / A converter is capable of decoding the wider range of sampling frequencies (up to 192 kHz) and bit depths (up to 24 bits ).

Compatibility with a wide range of Mobile Devices
The DA-10 is available with many connecting cables for compatibility with the widest variety of portable music players and smartphones. The USB-30 pin cable is compatible with many devices of Apple, including iPod, iPod touch, iPhone and iPad. The USB-Lightning cable is compatible with newer devices of Apple, including the iPhone 5 and 6, iPad Air, and other models with the wiring Lighting.
There is also, USB-micro "B" connector for compatibility with other smart devices, and is also included analog stereo 3.5mm-3.5mm cable to connect to a headphone output of a player, the cables with angled plug for secure connection.

Add and digital connectivity to an existing Hi-Fi system
At home, the DA-10 can still make your analogue Hi-Fi digital-compatible system. Connect the constant-level analog output of the DA-10 to the analog input of your Hi-Fi amplifier, then digital streaming music from your PC via micro USB-B input at high resolution up to 192kHz / 24bit or DSD64 (2.8MHz ) and DSD128 (5.6 MHz).

Long Lasting Battery Life with Battery Indicator
Featuring a high-capacity rechargeable lithium-ion battery of 3200 mAh, the DA-10 provides up to seven hours of continuous operation when connected to your portable music player or smartphone via USB. The multi-charging indicator function with LED lets you know the current battery charge level with the opening. When the battery is between 50% and 100%, flashing green. When the battery level falls between 20% and 49%, the LED blinks orange, and when the level falls below 20%, the LED changes to red, indicating that it is time to recharge.
When connected to a portable player through port 3.5mm, the battery life can be up to 24 hours. The recharge time can be short up to 3.5 hours when plugged into a USB charger with output of 1.5 A.

Sleek and Convenient Carrying Case
The included carrying case has a stylish design and includes two internal pockets for the DA-10 and your portable player or smartphone. The housing accommodates the portable device you have translucent plastic film, so that you can see and directly manipulate your device, there are safety belts to live everything in place. When folded closed, the carrying case also provides protection from mistreatment and even provides some protection against the elements.
With the portable USB-DAC and headphone amplifier DA-10 of Denon, your music will never sound better, and you can enjoy unchanged fidelity to the top headphones can provide.
