I have a Spector Euro 5 with the Tonepump preamp which is 18v boost only. With my Traynor DB800H, running through the active input, no matter the master setting or overall volume, if I have the EQ's up past halfway and the gain even higher than like 1/3 the way up, I get some nasty sound square-wave distortion going on. SS preamp or tube, worse with tube. Is the output from the Spector just too much for the Traynor's input? Is there something I can do about this short of not using the onboard EQ much? Having to keep the gain down this low really hinders my overall volume potential and I need all I can get, I'm sometimes running large rooms with no PA on just my Traynor and a SVT-410HLF.
