NAMES AND FUNCTIONS BASIC CONNECTIONS ENGLISH ADVANCED CONNECTIONS F.C.B.S. F.C.B.S. (Floating Control Bus System) is a communication system that connects up to four PM-KI-PEARL over a dedicated bus line so as to enable synchronized operations amongst them via 2-way data communications. Prepare the correct number of portable audio connection cables for the number of units to be connected. Any of the following two types of connecting cables can be used. ¶ Monaural miniplug ˱ monaural miniplug connecting cable ¶ Stereo miniplug ˱ stereo miniplug connecting cable Note: Do not use connecting cables that contain resistance. The figure below shows an example of four PM-KI-PEARLs connected by F.C.B.S. The top unit is the master unit with ID 1 and controls the three slave units with ID 2~4. When the master unit is operated, the input source, volume level, ATT feature, display and tone control ON/OFF feature of the slave units are operated in sync with the master unit. This function can be applied to various usages such as complete bi-amp with 2 PM-KI-PEARLs (page. 13), and 5.1ch multi-channel with 3 PM-KI-PEARLs (page. 14, 15). 7 F.C.B.S. Connection with the PM-11S2 Unit A multichannel system can be configured by connecting the PM-KI-PEARL units with a higher-grade PM-11S2 unit, using F.C.B.S. As higher-grade functions are provided with the PM-11S2 than with this unit, follow the connection conditions described below for an F.C.B.S. connection between the PM-11S2 and this unit. • Limit the number of PM-11S2 units to one and that of the PM-KI-PEARL units to up to 3. • Set the PM-11S2 unit as the ID 1 Master and the PM-KIPEARL units as one of the ID2-4 slave units. For details on connections, see the connection examples on pages 14 and 15. If the PM-KI-PEARL for the front L/R channels shown in the connection example is replaced with a PM-11S2, the audio quality of the front channels could be improved (also see the operation manual for the PM-11S2.) To use the 5.1 multichannel system shown as a connection example as a 2-channel stereo system, turn off the ID2 and ID3 amplifiers. Thus, the PM-11S2 can be used alone.
