Remote control operation
The MAESTRO is an eligible contender and tremendous performer
in a serious HIGH END stereo system. Besides the restriction to just 2x
selectable inputs, there is essentially no limitation for its use. To
enhance the versatility of the MAESTRO, the volume is remote
controllable. The unit responds to the © Apple remote.
