Connecting multiple PM-KI RUBY units (F.C.B.S. connection)

The Marantz F.C.B.S. (Floating Control Bus System) is the high quality sound system for link control between multiple PM-KI RUBY units (up to 4 units). Each unit is controlled via its ID number registered beforehand.

The ID numbers need to be set to an operating unit (master) and a subordinate unit (slave) receiving the command from the master. For slave units, register ID numbers in the order of command reception from the master.

ID numbers can be set for units connected by F.C.B.S. to perform linked operations such as switching the input source, adjusting the volume, muting, adjusting the volume balance, adjusting the sound quality and trimming the display brightness.

Furthermore, F.C.B.S. connection of multiple PM-KI RUBY units has the feature that switches this unit's output from stereo to monaural so that the unit can works as a monaural output amplifier. Follow the respective instructions to make the necessary settings.
