Compact USB digital-to-analogue converter that provides stereo RCA analogue outputs and both coaxial and optical digital outputs. With audiophile-grade Wolfson DAC/ADCs, it performs a 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 192 kHz are user selectable so user can achieve the exact performance level needed for any given circumstance. The converter has a built-in high quality headphone amplifier with both 1/4'' and 1/8” jacks, for connecting any headphones directly without the need for an adapter. It also features analogue stereo RCA line outs and coaxial and optical digital output connections, so a wide array of external equipment can be connected. Since virtually all high-quality audio equipment has a digital input, the converter’s 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. The converter is USB-bus-powered or an optional AC wall adapter can be used (not included).
