Page 18: Technical Description
Integrated Ampli- fier McIntosh has ever manufactured. The distortion limits for the MA6900 are no more than 0.005% at rated power output for all frequencies from 20Hz to 20,000Hz. Typical performance at mid frequencies is less than 0.002%. The true distortion readings on the MA6900 are so low, it takes special measuring techniques to make accurate readings. - Page 19 All inputs, outputs, and data ports are controlled by current amplification must be as linear as possible prior to logic circuits in the MA6900. The logic is changed by front the use of negative feedback. McIntosh engineers know panel push-buttons or by a microprocessor IR decoder.
