Notes Hyperbolic Conversion Amplication Circuit This kind of circuitry, developed by Yamaha, eliminates the only serious drawback of previously 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 Conversation Amplification Circuit does away with this problem, allowing the Yamaha MX-1000 to deliver superior performance constantly, without switching or cut-off, over its entire power range.

Advanced Power Supply Circuitry (APS) An amplifier is only as good as its power supply - this simple truth has prompted Yamaha to develop the APS circuitry incorporated in the MX-1000. The problem with conventional power sources was their tendency to produce pronounced voltage ripples during medium to large amplitude music signals, particularly under low impedance loads, together with voltage fluctuations in the power transistors. ASP solves this problem by providing an active power source that ensures stable voltage in the final transistor stage under all operating conditions, thus greatly improving power supply to the amplifier.
