On the new SansAmps (Para Driver/Bass Driver) there are 2 output level switches. One for the 1/4" and one for the XLR. The thing to note is that when the 1/4" is on Inst(rument) and the XLR is on Line, they are the same volume level. The Line on the 1/4" is a 10dB boost and the Inst(rument) on the XLR is a 20dB cut. just thought you all should know, and figured this is the board for it. Keep on kickin' @$$!
