I wanted to ask Mr.Mile or the other could answer, even fellow DIYer may experience the same thing with this problem, .. why the H900 standard when playing a kick drum, bass disappears (PA as SUB) ... the 4R or 8R load. but if for a bass guitar no problem, voltage regulator 45ac-90ac-ct ... 4kva. and I do not use nsl 32. where is that must be repaired or is there any other damage?
sorry my bad english

thanks and regards
