Most PC's and all laptops include an "on-board" audio system used for audio playback. Unfortunately, in order to keep the manufacturing cost as low as possible most PC manufacturers tend to use rather low quality electronics for these on-board sound cards. In addition, all motherboard mounted sound cards suffer from unwanted noise and distortion due to the fact that they receive a great deal of interference from the other closely mounted digital electronics.

The DFX USB Adapter uses high quality audio components, specially selected for low noise, low distortion, and high audio separation. In addition, the audio systems in the DFX Adapter are located away from the digital noise generated by the PC motherboard. These two important features allow the DFX USB Adapter to dramatically improve your PC audio quality.

The DFX USB Adapter provides the outputs for stereo systems as well as all six outputs necessary for 5.1 Surround Sound Systems.

The DFX USB Adapter also generates a full Surround Sound audio field from your normal stereo MP3 files. This makes full use of your Surround Sound audio system with normal stereo audio files.

If you plan to use your PC for recording, for example recording live music events or converting your LP record collection into MP3 files, the DFX USB Adapter is a very affordable way to insure top quality recordings. The audio recording systems built into most PC's are typically very poor, even much worse than the audio playback systems. The DFX USB Adapter gives you a recording quality that is only equaled by recording systems costing hundred's of dollars.

Our DFX Enhancer software restores the audio fidelity and depth that is lost during the MP3 encoding/decoding process. The DFX USB Adapter complements the DFX Enhancer software by greatly improving the hardware quality of your PC audio system. The combination of the DFX Enhancer software with the DFX USB Adapter hardware gives you the best possible audio quality from your PC.

The DFX USB Adapter interfaces with your PC or laptop using the standard preinstalled Windows USB driver. This means you don't need any special software installation procedures. Installing your DFX USB Adapter is as simple as plugging it into a USB port and then plugging your speakers into the DFX USB Adapter's speaker output.

Since the DFX USB Adapter is truly "plug and play" you can use it both with your desktop and quickly take it with you to use with your laptop for music listening on the road. It can be disconnected from your PC and reconnected to your laptop in literally just seconds.

One of the most important measures of audio performance is the Signal to Noise (S/N) ratio. This ratio shows how much undesired extra noise has been added to the audio signal by the audio system. When comparing the DFX USB Adapter to popular PC desktops and laptops we found that the DFX USB Adapter improved the S/N ratio by as much as 22 dB, and in no case was the improvement less than 10 dB. The laboratory testing showed similar dramatic improvements in reduced distortion and improved audio separation.
