ABOUT FCBS
FCBS is short for Floating Control Bus System. It is a
communication system that connects up to four PM-11S1s
over a dedicated bus line so as to enable synchronized
operations amongst them via 2-way data communications.
The FCBS connections can be made with either of the below
two types of portable audio connection cable. Prepare the
number of connection cables for the number of PM-11S1s to
connect.
• Connection cable with monaural ⇔ monaural miniplugs
• Connection cable with stereo ⇔ stereo miniplugs
Resistor connection cables are sold commercially, but they
cannot be used with the PM-11S1.
The below figure is an example of four PM-11S1s connected
by FCBS. The top PM-11S1 is the master unit of ID 1 and
controls the three slave units of IDs 2 - 4. When the master
PM-11S1 is operated, the input source, volume level, ATT
feature, display and tone control ON/OFF feature of slave PM-
11S1s are interlocked to the master unit.
This function can be applied to various usages such as
complete-bi-amp with 2 PM-11S1s, and 5.1ch multi-channel
with 3 PM-11S1s.
To turn power to multiple FCBS-connected PM-11S1s ON/
OFF, activate power in the order of lowest to highest ID
number and deactivate power in order of highest to lowest
ID number.
ABOUT THE BI-AMP MODE
The PM-11S1 is equipped with a bi-amp mode to enable a
complete bi-amp connection using two PM-11S1s. This
complete bi-amp connection is a high-end technique for
enhancing sound quality, proposed by Marantz. With it, the bi-
amp supporting speaker system is separated from the
preamplifiers that separately drive the low and high speakers.
(For more information, see Connection Example 3.)
The bi-amp mode is engaged by setting the operating mode
switch on the rear panel to “BI-AMP”.
In the bi-amp mode, the signals input to the L channel are
passed through the input buffer amplifier, split by the input
selector and transferred to the left and right volume amplifiers.
After that, the signals are sequentially sent to the left and right
voltage amplifiers and the left and right power amplifiers, and
ultimately output to the speaker output terminals. In the bi-
amp mode, the R channel input jacks cannot be used.
The below figure shows example displays in the stereo and
bi-map modes.

Note
Turn power to the PM-11S1 OFF before changing the
operating mode switch setting. Turning the power ON again
activates the new setting.
