Lets take a moment to talk about the audio outs. You will see there are ten, configured as pairs labeled Mix, A, B, C, & D (or six, labelled Mix, A, & B for the keyboard version). It is important to understand that even though there are ten jacks, there are only 8 routable outs (or 4 routable outs on the keybaord). Here is the way it works: When you route a signal, you choose the A, B, C, or D pairs and the appropriate panning position. But all audio signals come out of the Mix pair, until you physically plug a cable into a separate out. At that point, any signal routed to that out is removed from the Mix and comes out of that particular out. So if you plug cables into all of the separate outs, there will be no signal coming from the Mix outs.

To route something through the standard effects processor in your 2000, you need to set the output to A. But the effects actually only come out of the MIX outs. So if you plug cables into the A outs then, you will not be able to use the effects. For this reason, a typical way users will wire their units is to plug into the MIX, B, C, and D pairs.

The separate outs can also be used as insert points for external instruments, or to route a 2500 signal to an external effects processor and back into the instrument. For more on this, consult your manual.
