Hyperbolic Conversion Class A Circuit
This new kind of circuitry, developed by Yamaha, eliminates the only
serious drawback of previous Class A operation amplifiers.
These
had to switch to non-linear class AB operation above a certain load
current, causing a slight deterioration in the otherwise excellent
sound quality. The new Hyperbolic Conversion Class A circuit does
away with this problem, allowing your Yamaha MX-50 to deliver pure
class A operation constantly, without switching or cut-off, over its
entire power range.
