I use this amp for over 8 years now is an amp trs rib, only to change a fuse in 8 years! I tried other models of the era before buying, among other things at Yamaha, but I sduit silent on the sound quality of the amp and also its Aesthetics!
I bought the 4200 era nine francs (650 euros) which is quite rsonable a professional 400 watt amp (at 4ohms).
This is an amp that does not heat as well ventilated trs I rarely used full (and always under 8 ohms or 240 watts dlivre it), as we feel the power derrire, it does not saturate, nor tired rgime up and does its job correctly regardless of the place (I used a lot in places with lots of smoke, and still breathing like new!)
it is up communties in bridge XLR inputs are either mle or femmelle choice.
One small "catch" the volume potentiomtres crash a little over time, "but it's a bit normal after 8 years, a little cleaning here we go again!
I do not regret my purchase in any way, and I would do the same choice if c'tait again.
