Shown on this page is a close-up photo of the remote control provided with the Z-base 575. As you can see it is small. The controls are very basic, but provide everything you need to use the 575 and adjustment to your listening taste.
In order for the remote control to function, you need to make sure that the master power switch on the rear of the 575 is in the on position. This puts the unit in standby.

You can then turn the unit on from the remote and change the settings. The Phase Cue buttons are what you use to adjust the surround sound effect.
