Rotel is a family-owned business, founded in Japan over 55 years ago
There is no substitute for experience. More than fifty-five years of designing, engineering, and manufacturing audio/video components has put us at the top of the audio field. We have always been a family owned business. That is why we take the time to build, test, and critically evaluate each new model before it goes into production. Our reputation is personal.
It's all about the sound.
Much of Rotel's success in sound reproduction can be attributed to our engineering philosophy called Balanced Design Concept - a disciplined synthesis of physics, electronics and mechanical engineering.
Balanced Design Concept revolves around three principles: parts selection, circuit topology and critical evaluation.
Our engineers spend countless hours selecting and testing parts from an array of suppliers to give our products the best reliability and acoustic advantages. It costs a little more, but we believe the benefits differentiate Rotel's quality from that of mainstream hi-fi manufacturers.
It's not enough to simply use better parts. Where you put them is equally important. That's why we rely heavily on something we call Symmetrical Signal Trace design. This keeps each channel's signal path identical to the others to preserve imaging and sound staging. We also use 'star' grounding techniques wherever possible to improve performance - a method of terminating all ground points in a star-shaped pattern on a single plane.
We've found that human hearing is more sensitive than even sophisticated instruments in the hands of experienced engineers. That's why we run listening sessions at each development stage, and use our participants' feedback to refine the product before it goes into production. This ensures the performance of a new model is as good as it can possibly be.
NO DETAIL TOO SMALL
Rotel engineers choose components from around the world in order to make each product the best they can. You are likely to find capacitors from the United Kingdom and Germany, semiconductors from Japan or the United States, while toroidal power transformers are manufactured and wound in our own factory.
THE HUMAN TOUCH
Rotel has over 50 years of electronic design, precision engineering and manufacturing expertise. We know through experience that we can’t rely on a simple “textbook” formula to produce great results. Creating musical magic is as much art as it is science. Parts that measure the same may not sound the same. Identical parts can be oriented in different ways in a signal path and produce different results. That’s why our engineers obsess about listening to our designs at every stage of engineering through to final production.
ENGINEERED FROM THE GROUND UP
An electronic component is never merely a collection of parts, regardless of their quality. A circuit – literally the path the electronic signal must follow from input to output – is a complex, interactive environment. Even the best parts poorly placed will interact with each other in negative ways. Skillful engineering, informed by both science and experience, is required to optimize the layout so that the investment in critically selected parts that have a direct effect on the sound quality results in audibly superior performance. It’s a painstaking process requiring critical evaluation at each stage of the design, but it is where our engineers have proven themselves to be the best in the business time and again.
