Connecting multiple PM-12 SE 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-12 SE 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-12 SE 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

Making the F.C.B.S. connection

To use multiple PM-12 SE units, make this connection in addition to audio connection. For details on each connection feature, refer to the respective instructions.

• "Stereo complete bi-amp connection"
• "Connection for 5.1 Multi-channel Playback"

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.

• Φ3.5 Monaural mini plug ←→ Φ3.5 monaural mini plug connecting cable
  
• Φ3.5 Stereo mini plug ←→ Φ3.5 stereo mini plug connecting cable
  

NOTE: Do not use connecting cables that contain resistance.

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.

• The PM-12 SE F.C.B.S. function is only valid between the same PM-12 SE models.
• To turn the power of multiple F.C.B.S.-connected units ON/ OFF, switch the power ON in order of lowest to highest ID number, and switch the power OFF in order of highest to lowest ID number.

How to set ID number for F.C.B.S.

1. While holding F.C.B.S. ID on the rear panel, press .
2. Turn INPUT SELECTOR on the unit to select an ID number.
   • For a master unit, ID number 1 needs to be assigned. For a slave unit, set any of ID numbers 2 to 4.
3. Again turn the unit on.
   The ID number appears on the display for around 3 seconds.
   • The setting is saved.
   • The unit registered as a slave shows "SLAVE" on the display.

• If using this unit by itself as a stereo amplifier, set the ID number to "0". (Default setting is "0".)
• If the ID number is set to a number other than "0", this unit cannot be used for standalone operation.

Stereo complete bi-amp connection

This mode enables the two amplifiers connected to this unit to function as one monaural amplifier. To use this mode, two F.C.B.S. connected PM-12 SE units are required.
To switch the mode, use the AMP MODE switch on the rear panel while the power is off.
If this unit is set to the bi-amp mode, "BI-AMP" appears on the display.
In bi-amp mode, connect to the left channel input connector. The right channel input is disabled.
The same signals are output from the left and right speaker terminals.

• Be sure to turn the power off before operating the AMP MODE switch. Settings can be configured when the power is turned on.
• When in bi-amp mode, the R channel input connectors cannot be used.
• When in bi-amp mode, the signals input into the L channel are output from both channels. Therefore, the same signals are output from the L channel and R channel in RECORDER OUT, headphones jack.
• Speaker systems connected using complete bi-amp connections must support bi-amp connections. Before connecting your speakers, check in the instruction manual that came with the speakers or contact the manufacturer to confirm whether they support bi-amp connection.

Connection for 5.1 Multi-channel Playback

Three PM-12 SE units can be connected by F.C.B.S. and used through linked operation. For details on F.C.B.S. connection, see "Examples of Connections".
Connect the outputs of players that have 5.1 channel analog outputs to each of the three units.
If using an active subwoofer, see the instruction manual that came with the subwoofer for further instructions.
Set the ID numbers for the three amplifiers as explained in How to set ID number for F.C.B.S.

• When the ID 1 unit is operated, ID 2 and ID 3 units will operate in sync.

Speaker Positioning for Super Audio Multi-channel Sound

In order to enjoy Super Audio CD multi-channel sound with the best possible acoustics, it is recommended to position speakers as specified in ITU-R BS.775-1 of the International Telecommunication Union (ITU). Super Audio CD multichannel discs are recorded and mixed so as to achieve the optimum effect with a speaker system laid out as specified in ITU-R BS.775-1.

• With Super Audio CD multi-channel discs, the music signals are basically recorded using 5 channels (3 - 6 channels sometimes), but in some cases, LFE (for subwoofer) is recorded as a sixth channel.
• Each disc indicates how many channels have been recorded on it.
• The basic layout is 3 speakers in the front and 2 in the back since multi-channel discs usually have 5 channels. The 2 front, 1 center and 2 surround (rear) speakers should be set in a circle around the listening point. If using speakers of differing sizes, adjust volume balance from the amplifier.
• The location of the subwoofer in the figure is just for explanatory purposes. It can be located anywhere in the room. For connection and positioning instructions, see the instruction manual that came with the subwoofer.

• ITU (International Telecommunication Union)

The ITU is a special organization of the United Nations. It consists of a number of organs, one of which is the Radio Broadcasting Section.
ITU-R BS in the recommendation which consists of standards relating to broadcasting (audio) operations, one of which is the ITU-R BS.775-1 which governs "multi-channel stereo sound systems".

Explanation of terms

MM/MC cartridge
There are two types--MM (Moving Magnet) and MC (Moving Coil)--of cartridges for turntable. As the output levels for these two types of cartridges differ, the setting of the phono equalizer that is mounted in this unit must be switched according to the type of cartridge for your turntable. Change this setting in the "PHONO" section of the setting menu.

Speaker impedance
This is an AC resistance value, indicated in Ω (ohms).
Greater power can be obtained when this value is smaller.

Protection circuit
This is a function to prevent damage to devices within the power supply when an abnormality such as an overload, excess voltage occurs or over temperature for any reason.
