Tony,
Just got back from tonight's gig.
An addapter cable comes with the 5500 that has a pair of RCA plugs on one end, and a 1/8-inch stereo plug on the other. Plug the 1/8-inch plug into the remote reciver where you see the musical note icon. At the other end, you'll need to buy a pair of RCA to 1/4-inch male, mono addapter plugs. I got mine at Radio Shack, but I'm not sure where to tell you to get them in Cozumel. This will plug into the standard, stereo output of the keyboard (left & right out).
Now, on the back of the remote reciever you'll find a small switch. Place the switch in the full up position (6 Ch. Direct).
After plugging in all the appropriate speakers and hooking up the remote, turn on the main power, then turn on the secondary power with the remote control. Using the effects button, select Prologic II Music. This will provide power to all the speakers, including the center and sub.
The speaker volumes can be adjusted independently, which is a neat feature. Turn the sub down to about 20 to 25 percent. Now turn up the volume of the front, rear and center speakers to maximum.
Using the remote control, press the TEST button and allow the system to test itself. It will send a white noise signal through the front pair, rear pair, center, then the sub. Press TEST again to stop the process.
Now you're ready to play music. The best suggestion is to fire up a midi file, then walk around the room and set the volumes until everything sounds OK to you. Keep in mind, however, that you do not have an EQ with the system, therefore, your EQ control will be done using the keyboard's onboard EQ via the keyboard's mixing panel.
Hope this helps, but if not, I guess I'll just have to fly to Cozumel and set it up for you. It's a rotten job, but I'll make the sacrifice.
Gary
