Give your PC a full range of digital possiblities and connect your computer to your Hi-Fi or Home Cinema system... quickly, easily, and with audiophile sound quality!

The UD-10 USB Audio Converter includes balanced digital  AES/EBU (110 Ohm via XLR), S/PDIF (75 Ohm via RCA or BNC), TOSlink optical, and USB input.

Use The Trends UD-10 for: 

• Audiophile USB Transport (provide a digital interface to connect to your own DAC)
• External USB sound card for PC and Mac
• PC/Mac USB Headphone Amplifier
• PC/Mac USB DAC

Packed with top-grade parts and engineered to provide the very best sound, the UD-10 effectively isolates the audio signal from interference from within the PC case, e.g. high-frequency data signals, switching-mode power supply, fan motors, etc.

Proprietary impedance matching circuits for AES/EBU (110Ω) and Coaxial (75Ω) digital outputs apply specially designed pulse transformers for each AES/EBU and Coaxial output. The most pure, accurate, standard digital signal is then regenerated with minimum interference and jitter. It is a very dynamic way to convert the computer (Desktop, Laptop etc.) to a first class CD Transport

• Plug-&-play for PC and Mac 
• High-end Burr Brown DAC for USB audio conversion 
• Unique digital outputs (optical x1, coaxial x2 (RCA & BNC), AES/EBU x1) 
• Proprietary dual power regulation circuits design 
• Separate digital/analog grounds to reduce interference between digital and analog signals 
• High-accuracy crystal clock (±10ppm) 
• Applied RS422 driving IC to concurrently drive 4 groups of balanced & non-balanced digital outputs 
• Proprietary impedance matching circuits for AES/EBU(110Ω), Coaxial (75Ω) digital outputs 
• Specially designed pulse transformers for each AES/EBU and Coaxial outputs 
• USB Connecting cable and 3.5mm to phono adaptor included 
• Plug-and-play without driver installation for PC (Windows 2000, Windows XP and VISTA) and Mac OS X operating systems

Digital-to-analog conversion is accomplished with the aid of the Burr Brown PCM2704. Other circuit details include dual power regulation circuits, separate digital/analog grounds, highly accurate crystal clock (±10ppm), transformers for each AES/EBU and coaxial outputs to isolate interference. While the UD-10 can be powered by the USB, we heartily recommend the optional external power pack for best performance. (AA size rechargeable battery 1.2V x4=5V. Do not use normal batteries with 1.2V x4=6V.)

From TNT "... a look at the specification of the UD-10 makes me wonder how they do it for the price! The casing is well made from aluminium, with a good range of connectors. Would you believe; there are no less than four digital connectors (optical x1, coaxial x2 (RCA and BNC), AES/EBU x1) should you wish to use your own DAC with the UD-10 instead of the built inDAC! Inside we find Sanyo Oscon, and Elna Silmic capacitors, and a Burr Brown PCM2704 DAC chip. There is no doubting that the UD-10 has been built with sound quality in mind, rather than being designed to sell at a huge profit!
