Bill,
The PSR-3000 has the same outputs as the 2000. There is an Auxiliary Input, but the only outputs are the standard outputs and line-out which is also labled as auxiliary out, which is a fixed level.

As for using a Y adapter, this usually results in an impedience matching problem and distortion, or decreased overall performance.

You can run from both the line out (RCA) and standard output using two systems--that will work just fine. The only stumbling block would be matching the volumes between the two systems.

Good Luck,

Gary
