Minor Schematic Error

I just found out, that the inputs on the schematic are labeled wrong. The amp has two inputs (Bright and Normal) and each input has two jacks (1 and 2). The supplied schematic has the 1 and 2 jacks switched. It makes more sense to have the 1M resistor on input jack and the wiring diagram is also in line with that.

I checked with other schematics I found in the net, like this one.
