AUDIOENGINE D3 Portable USB audio converter (digital-toanalog converter)

Transit Pro is a super-high resolution USB/DSD (Direct Stream Digital) converter that takes audio signal from your computer and delivers the highest quality digital (optical)/analog signal to any audio component. The key to Transit Proʼs outstanding audio performance is its 32bit/384kHz digital "engine,” which delivers a super-wide bandwidth frequency response, ultra-wide dynamic range and an extremely low noise floor. There are eight user-selectable sampling rates between 44.1 and 384kHz so you can achieve the exact performance level needed for any given circumstance.

Transit Pro has a built-in high quality headphone amplifier with both ¼-inch and 1/8-inch jacks, for connecting any headphones directly without the need for an adapter. Transit Pro is USB-bus-powered or you can use an optional AC wall adapter (not included). Transit Pro is the answer when you need to deliver a reference-quality digital signal from your computer to an external audio component.

Super DAC is a USB digital to analog converter with stereo RCA analog outputs and both coaxial and optical digital outputs. With audiophile-grade Wolfson DAC/ADCs, the M-Audio Super DAC performs 24-bit/192kHz high-definition audio conversion over a USB 2.0 connection. This results in the highest possible audio quality, which is critical for users who want to connect their audio equipment to their computer but are not satisfied with the sound quality of the typical computer sound card or the compression limitations of a Bluetooth connection. Six sampling rates between 44.1 and 192kHz are user selectable so you can achieve the exact performance level needed for any given circumstance.

Super DAC has a built-in high quality headphone amplifier with both ¼-inch and 1/8-inch jacks, for connecting any headphones directly without the need for an adapter. It also features analog stereo RCA line outs and coaxial and optical digital output connections, so you can easily connect a wide array of external equipment. Since virtually all high-quality audio equipment has a digital input, Super DACʼs optical  and coaxial digital outputs are perfect for driving that equipment with a pure digital signal—especially valuable since most computers do not have a digital output.

Super DAC is USB-bus-powered or can use an optional AC wall adapter (not included). The M-Audio Super DAC is the answer when you require reference-quality sound from your computer.

• Supports resolutions up to 1920 x 1080 (1080p Full HD) including 720p and 1600 x 1200 for HDTV monitors or projectors
• Gold-plated HDMI connectors provide wear and corrosion resistance to ensure a long lifespan
• With this version, we added a standby function to lower the energy consumption
• On the past design of HDMI to VGA converters, if HDMI port was connected to the device, VGA port will keep working, now, we added an environmental friendly standby function to make sure when there are no signal outputs from VGA, convertor will be at a low energy consumption, in the meanwhile to produce less heats
• Lower energy consumption, heat-reduced, extends the life of the product; after receiving customer’s feedback that the product will get overheated, we improved the operating current of the product to lower from 220mA to 120mA
• More stable performance and not easy to skip the screen, we improved the design of chips, mainboard and circuit to make it more stable when transmitting signal
