I have an old Carvin 300 watt head (1986), that is really pretty decent. Carvin was making some nice stuff back then. Only weakness is its DI output, if it is even a DI output. I've tried to connect this to a PA board with poor results. It is a standard 3-pin XLR labled "Balanced Output." The signal level to this output is controlled by the front panel volume knob that also controls the speaker output. The problem is that this signal is very hot for the PA. With the PA input gain at minimum it clips long before the speaker volume is at an acceptable level. Any ideas on a work around or modification? I'd love a buffered DI with an independant level control. I'd buld it if I knew how to design it.
