Pose,

The 6-channel direct switch on the back of the remote reciever must be selected in order for this to work. If the switch is in the down position, it will not work.

Also, with all speakers hooked up, and the switch in 6-channel direct, use the remote control and run a speaker check to make sure all are functional. You should hear sounds coming from each set of speakers, plus the center and bass while the testing procedure runs.

I'm not familiar with the PSR-9000s output, but I assume it is stereo, and would be very surprized if this was not the case.

Also, try swappig the output plugs from left to right channel, and vise/versa and see if this changes anything.

Unfortunately, you're on the other side of the country from me, so I can't look over your shoulder to see what is wrong.

As for the dirrerence in sound in comparison to my other keyboard amps, the Z-5500 is extremely crisp, clear and really makes a big improvement in vocals and mid to high frequency sounds. The sub, naturally, really rocks and hit the audience with that gut-thumping bass that packs the dancefloor.

Good Luck,

Gary
