It must be good 3-4 years I own this amp, buy bundled with the speakers (who have dropped out when I wanted to do a little test ...) and the mixer Expelec 002af mix.
Correct power for use inside and outside (as long as the enciente are up to the crowd and not too large), but inside, the fan noise is unbearable quickly, unless turning up the volume of the zic ... which is more enjoyable in the long run neither for oneself or for those around him ...
In the end, to parties with friends, it will be necessary, but indoors, in the studio when producing his own music, at all costs privileged active speakers (integrated amplifier).
