Power Output - YORKVILLE A4.4 Manuel De L'utilisateur

18. Power Output

All values are in WATTS. Measurements were made at the 0.1% distortion point.
Some CONTINUOUS AVERAGE POWER measurements required line currents
greater than 15 Amps. The BURST measurements use a 10 mS burst at 1KHz with a
1/8 second pause between bursts. The 1KHz burst represents the maximum possible
sine wave output power.
