Introduce the USBe Perfect –
THE ANSWER to USB Signal Transmission
Walter Liederman, owner of Underwood Hifi and Core Power Tech A/V had these comments when asked about the USBe Perfect –
The USBe Perfect is designed to yield the best results when using USB (Type 2 or Type 3) in your audio system. Now that USB has become the transmission medium of choice, we saw a need to create the absolute best connection for the Highest Fidelity result.
Carefully designed and meticulously Alpha and Beta Tested, the results were unanimous. USBe Perfect improved every system it was placed in. We decided to bring this product to market with an Introductory Price of $299. This is a special offer during these difficult times – the actual retail price is 499 dollars.
USBe Perfect Technical Highlights
The USBe Perfect is designed to minimize signal degradation effects such as crosstalk, jitter, and inter-symbol interference (ISI) that negatively affect audio quality. This is achieved with a comprehensive set of features that optimize the entire USB signal transmission chain These include –
- Integrated Regeneration of the USB 5V power from the source.
- Input stage equalization. Each input channel re-equalizes the signal gain with transmission frequency to compensate for cable losses. (assumed to be 1 to 3 meters)
- Output stage matching. The outputs stage provides tailored de-emphasis to compensate for impedance mismatches at the signal termination.
The following plots show the input and output of typical implementation based on USBe Perfect with a USB 3.0 Type A connector and a Standard USB3.0 3-meter long cable
Note the greatly improved Eye Mask indicating the potential for less signal error and greater transmission efficiency.
