Overview Connections Playback ENGLISH 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. Preparation for F.C.B.S. connection n Making the F.C.B.S. connection To use multiple PM-KI RUBY units, make this connection in addition to audio connection. For details on each connection feature, refer to the respective instructions. 0 "Stereo complete bi-amp connection" (v p. 11) 0 "Connection for 5.1 Multi-channel Playback" (v p. 13) Prepare the correct number of portable audio connection cables for the number of units to be connected. Either of the following types of connection cables are adequate. 0 Φ3.5 Monaural mini plug O N Φ3.5 monaural mini plug connecting cable . 0 Φ3.5 Stereo mini plug O N Φ3.5 stereo mini plug connecting cable . NOTE 0 Do not use connecting cables that contain resistance. n Connection example In the connection of the following example, an unit with ID number 1 acts as a master amplifier to control all the other slave units with ID numbers 2 to 4.
