70% Power GuaranteeΈχω την εντύπωση ότι το 70% guarantee αναφέρεται στην χρήση όλων των τελικών σταδίων και όχι σε 5ch.
Marantz has the 70% power guarantee, meaning that a minimum of 70% of the stereo power indicated in the specification section will be available when 5 channels are simultaneously used. A lot of misunderstanding about power rating has been created by claiming the highest possible output power as a unique selling point. Measurement often has been done on only 1 speaker drive, with lower impedance than 8 ohms and high THD (total harmonic distortion) acceptance. A standard THD value is 0.08%. The lower the better.
