NOTES:

2. At this power level, the soft clipping circuitry is beginning to activate. It functions to “round off” peaks rather than hard limit as in most linear

amplifiers. This helps to give this amplifier a pleasing sound during limiting. Moreover, this feature also makes the amplifier “sound louder”.

3. This time allows the amplifier to reproduce large, sustained peaks without shutting down, yet is adequate to protect the amplifier output from

shorted speaker lines.
