The divider effect and SUT gain

The first white paper from the Clinamen technical library: 'The voltage divider effect and SUT gain'" is available in PDF format. You can download it here

Topics covered in White Paper No. 1: 'The voltage divider effect and SUT gain"

The relationship between a Moving Coil cartridge and a step-up transformer goes beyond the simple voltage boost provided by the SUT at its secondary winding. The choice of the step-up ratio also determines the reflected impedance that the cartridge sees at the primary side and, consequently, how its signal is loaded and transferred. Furthermore, this affects the cartridge's tracking capability, as the reflected impedance directly influences the damping of the moving assembly.

However, how much of the SUT's theoretical gain is actually available at the output? In White Paper No. 1, we will answer these crucial questions to properly interface an MC cartridge with a transformer step-up.

We will analyze in detail the 'voltage divider effect' occurring between the SUT and the cartridge, learning how to select the correct SUT gain based on the specific parameters of your system. We will extrapolate practical rules derived from physical and electrical considerations.

These principles form the necessary foundation—a prerequisite, though not entirely sufficient on its own—for the phono pickup to fully express its acoustic, timbral, and tracking capabilities."

Each PDF is part of a technical series, currently divided into eight topics, created to be preserved and consulted over time. Together, these white papers form an original library resulting from over fifteen years of research and development in the Clinamenaudio laboratory: an open work synthesizing the principles of audio design according to the 'Natural Way.'

The price of each individual technical article is 15 euros. Rather than a simple purchase, your download represents direct support for independent research that addresses high fidelity through objective analysis and instrumental verification, in an industry where myths and trends all too often take the place of physical facts.
