Yamaha MX-800 is a stereo power amplifier that provides superior performance without switching or cut-off over its entire power range thanks to the new Hyperbolic Conversion Amplification Circuit. The Advanced Power Supply Circuitry ensures stable voltage in the final transistor stage under all operating conditions. The power peak meter indicates the power output on a logarithmically compressed scale from 0.002 to 600 watts (—50 to + 5dB), independently for the left and right output channels. Three LOAD selectors adjust the peak power display according to the speaker load impedance.
