This is my mommy gave to me, here almost a year now. This beautiful beast delivers metal 2x125 watts into 4 ohms stereo, perfect for my passive speakers Alesis. Construction well muscled and sound neutrality, here is what I needed. It seems it's more DJ-oriented, but it is needy in my home studio and I never exceed 9 o'clock on the volume knob. This is more than enough to hear me, and of benefiting the area when the window is open. It is not at all the low-end and do not dream, not a Crown, but it amplifies it does it well. Its input connector is 2 XLR sockets 2 socket inserts and built-in jacks as well, the output connector is made of 2 Speakon Speakon or 1 (bridged) + 2 combinations Banana / screw. Its control elements are a power switch, a controller gain for each channel, a stereo / parallel / bridged, a Ground Lift and level-select-input (0.77 dB, 1.44 dB, 0 dB). It is equipped with protection circuits, the chassis is made of steel and aluminum front panel and it does virtually no heat. It can be inserted into a 2U rack, weight is 10 kg. For cons, I have in my possession two other passive speakers 6 ohms but I do not know if I can also connect this amp (if anyone can tuyonner me about it, I'd be delighted. But no I kidding, it's not a thing to do, CAUTION!). I am not aware of the price of this amp since it is a gift and I am anxious for this Omnitronic. If it blows a little but only when no music through it, just the ignition, the speakers emit a slight hiss but nothing too serious.
