i bought this amp originally to power a bass guitar rig (with bbe bmax preamp), for this purpose with the cabs that i built myself it was brilliant, lightweight, powerful and simple to use, but when i selected this set up i also had in mind that it would also be good for PA duty.
the power ratings for this amp are a little unclear in the description as it doesnt state the RMS power rating, however, it is a powerful amp, works very well with 4 ohm loads on each channel, the specs say it will go to 2 ohms a side, i have not tested this tho.
i think the ratings in the description are peak values, and in my opinion (purely a guess) from using PA amps over the years i would rate the power output around 450-500 @ 8 ohms, and 700-800 @ 4 ohms, still very respectable power/cost ratio, then factor in the weight, i am happy with this amp overall.
i have experienced 1 fault occur with this amp, this happened recently whilst still within its 3 year guarantee, THOMANNS fixed it with exceptional speed. Awesome customer service!
