Hello to all,
I'm just doing some simulations using the EP1500 schematic that can be found on the net, and the AC analysis shows a frequency response that start dropping considerabily at 100Hz

I attached the graph of the AC analysis

I think it can be due to the double .15uF cap in series before the OP-Amp that drives the output stage, as You can see in the other attached image

Does anyone of You have a frequency response graph of the behringer in order to check it?
Or, could it be tha the values of the two .15uf caps reported in the schematic are wrong?

Thank You Very Much
