Scott,

Yes, I'm using all speakers, 5 satellites and the sub. Just plug an 1/8-inch, male, stereo to 2 1/4-inch, male jacks, into the side of the remote where the icon shows a musical note. The two 1/4-inch male plugs are then connected to the keyboard's output. This 1/8-inch connection is the input for external, stereo devices such as CD players, etc. Next, there is a switch on the back that must be set in the up position to 6-ch direct. That's all there is to it. You can set the individual volume levels of each speaker pair and the sub using the remote control device. However, the only way you can use the boost control is using the main control volume knob.
