Current limit onset definition?


My Spectral DMA 180 indicates in specs that Current Limit Onset is 40 amps. It also says peak current 60 amps. Anyone know what this means?

Peak current is akin to saying a circuit breaker may let through 150A of *instantaneous* current before it trips (in fact, in a short circuit that many instantaneous amps aren't unusual before the breaker trips or wires start to melt); and continuous current is akin to saying the breaker may trip when you reach that many continuous amps flowing through.

Instantaneous current will only be available in low impedances, and as a "spec" it's mostly meaningless, other that to probably somehow try to infer high slew rates (though they are spec'd in Volts, so there, this is why it's really meaningless to me)...
The "6" is indeed an "8" - 8A. see this clear picture of the back panel at http://hifi.myinsales.ru/collection/usiliteli/product/spectral-dma-180

Newer amps have 5A fuses.
