Full explanation on YBA’s balanced input output

SKU: N/A Category:

The choice of materials is an important part of the design of YBA amplifiers. The chassis of the Signature is made from a block of aluminum milled in the mass. Besides absolute rigidity, it also allows different internal boundaries free from electro-magnetic interference.

This mechanical structure allows mounting on 2 levels of components that are fixed on either side of the central portion! The transistors are mounted on a solid aluminium block with special mica wafers, which improves heat dissipation to avoid thermal distortions.

All of the materials used to manufacture for YBA electronics are non-magnetic. The selections and tests of the French manufactured components, are more precise to avoid any unbalanced effect and increase reliability.

YBA Signature transistors are specially selected in order to be perfectly matched. The mono amplifier is a derivative of the stereo power amplifier.
