The USB isolator is a device that will pass USB signal from input to output connector, while providing galvanic isolation between them. USB isolators are used in applications where direct USB connection can create noise (ground loop noise to audio or measurement), direct connection can be unreliable (noise to USB signal) or where isolation is →

The Valve Wizard web page is about tube amplifiers. They have a very good document on grounding issues in tube circuits. So read their 16 page Grounding document to learn about grounding (both general information and tube amplifier specific information). →
Here is one piece of additional information to my ground loop postings. Ground loops can be introduced when different components in audio systems are connected with standard audio cables, and these loops can cause annoying interference. Grounded audi components generally carry significant currents in their ground returns. Texas Instruments Application Report SLOA143 – October 2009: →
The Rane Library has many interesting audio relaed technical documents. The most famouse of them is Note 110 Sound Systems Interconnections – it is a classic. Just few days ago I happened to look around at The Rane Library, and found some really interesting material related to audio systems and ground loops: Grounding and Shielding →

As a result, the trend away from legacy single-channel isolated systems to applications utilizing multi-channel isolation has led to the introduction of new isolation components. Many of these applications →
Rane Sound System Interconnection note, originally written in 1985, continues to be a very useful reference. It’s popularity stems from the continual and perpetual difficulty of hooking up audio equipment without suffering through all sorts of bizarre noises, hums, buzzes, whistles, etc.– not to mention the extreme financial, physical and psychological price. Many things have improved →
Would this be suitable logo for my groundloop postings? →
Many laptops are pretty well known for having terrible audio interfaces. There are usually noise and grounding issues. This article tries to describe the reasons for those problems. Grounded power supply issues A recent post Yet Another Dell Laptop Audio Grounding Problem blog posting documents a well known and horrendous audio problem found on many →
As electronics applications continue to become more compact and has more and more features in same package (think about modern smart phone or tablet), requires system engineers to use multiple power rails and mixed disciplines of circuit design (mix both analogue and digital parts tightly). A typical tablet will consist of items such as a →
