NuForce uDAC-2 (Version 2) The NuForce uDAC-2 is a high-performance USB Digital Audio Converter (DAC) that connects your personal computer's audio with your home stereo, desktop sound system, or headphones. The quality and versatility of the uDAC's performance belies its diminutive size. With its extensive power supply, filtering capabilities and charge-pump circuit as a foundation, the uDAC processes incoming data via a USB audio receiver.

DAC and Headphone Amp User Guide Introduction CD-ripping software is capable of reproducing “bit perfect” digital music data (16 bit/44.1kHz) from audio CD files stored on the computer’s hard drive. In addition to CDquality music, some online sites are now offering 24 bit/96kHz music files. Thanks to larger and increasingly economical hard-disk capacity, consumers can store the highest quality music files on their computers. However, extracting good sound from the computer poses problems.
DACs. Digital Connections There are two methods for extracting digital signals from your computer. The universal serial bus (USB) connection is the de-facto standard for just about all peripherals: printers, digital cameras, etc. The USB allows the computer to speedily recognize a connected device. Some computers also incorporate the Sony/Philips Digital Interconnect Format (S/PDIF), a coaxial connection with excellent transfer properties.
If you use a USB hub, choose one with its own AC power adapter. In areas that produce high levels of radio or electrical interference, upgrading to a quality USB cable, i.e., one with extra shielding and a ferrite bead (the cylindrical collar on one end of the cable) to help eliminate noise. Once you’re properly connected, your computer’s operating system should automatically detect your NuForce product. From that moment on, all you need to do is enjoy the music.
The Icon HDP permits an S/PDIF connection from your computer, if that’s your preference. For best results, use a high-quality S/PDIF cable. Once the connection is made, select S/PDIF in your System Preferences Audio Device settings. Analog Connections You need only connect headphones to your NuForce device’s headphone jack and adjust for volume with the unit’s volume control.
Typically, OE types exhibit sensitivities of about 100dB/mW, whereas IE devices can be 10dB higher or more, e.g., 110dB/mW. Assuming a 10dB difference, the lower sensitivity OE headphones require ten times more power to achieve the same volume as the IE type. If you’re using OE headphones, you’ll appreciate the NuForce Icon Series’ power capability. Your headphones will sound clearer and more natural.
