Figure 8.6 Macro-Tech 2402 Minimum Power Matrix

Minimum Power Notes:

All minimum power specifications are based on 0.1% regulated AC mains and an ambient room temperature of 70°F (21°C). International units with multi-tap transformers are specified for the worst-case transformer tap (normally 100 VAC, 50 Hz). The standard EIA power measurement (RS-490) is not identified here because it is identical to the FTC Continuous Average Power specification.

1.A 1-kHz sine wave is presented to the ampli- fier and the output monitored for nonlinear dis- tortion. The level is increased until the THD reaches 0.1%. At this level the average power per channel is reported.

2.A sine wave is presented to the amplifier over the range from 20 Hz to 20 kHz and the output monitored for nonlinear distortion. The level at each frequency is increased until the THD reaches 0.1%. At this level the average power per channel is reported.

3.A 1-kHz sine wave is presented to the ampli- fier and the output monitored for nonlinear dis- tortion. The level is increased until the THD reaches 0.05%. At this level the average power per channel is reported.

4.Continuous power in the context of Federal Trade Commission testing is understood to be a minimum of five minutes of operation. Harmonic distortion is measured as the RMS sum total and given as a percentage of the fundamental output voltage. This applies for all wattages greater than 0.25 watts.
