I use the AS 402 for two years now, as amp back (small rooms, cafe conc '). Never found wanting, yet it has little rack space to breathe. I bought it on the advice of the seller, specialist in sound system in the region of Marseille / Aix, and if it again, I repeat the same. Less than 300 at the time for twice 200W RMS, nothing to say.

Matos adviser, even in time.
