Notes re Power Consumption and Heat Loss measurements:
All measurements at 230 VAC 50 Hz power input
1.
Idle: amplifier active, but no audio output
2.
1/8th. Power: constant sound level at one-eighth maximum rated output per channel (audio mainly clean, only occasional clipping)
3.
1/3rd. Power: constant sound level at one-third maximum rated output per channel (audio beginning to become compressed, limited or heavily clipped)
