Modular system:
In the modular system several independent modules carry out the same functions as the main units. There are diverse types of power supplies, sources of audio, as tuners FM stereo and mono, MP3 player or input modules for other musical sources.
There are also optional modules for telecontrol. (The telecontrol acts through wire 15 of the left channel).
This system is more flexible as for number of channels, being possible to distribute the audio sources throughout the installation. The auxiliary power supplies can also be placed in any part of the installation if it is necessary.

Equivalent products:
An input module PC3110, a tuner PCD3666 or an MP3 player PC3680 can be used as audio sources.

Cable to be used:
The connection to the distribution line can be carried out using cables, Mod. P9910 (for one mono / stereo channel) or P9950 (in the case of being an installation with announcements and/or intercommunications).

Material used in the example:
1 power supply P3225 and optionally 1 telecontrol module PC3810 - 1 socket module PC3811 - 1 frame KC9302

Installation recommendations:
The connection to the 230V mains electricity supply will be made using 1 mm² wire gauge minimum with double insulation. It is also essential to connect the earth for safety reasons and improved operation.
It is recommended that the mains electricity supply cables are as far away as possible from the exchange circuits.
The system cabling should be carried out separately from the mains electricity supply in keeping with regulations.
Do not locate this product in damp areas, near to sources of heat or in potentially explosive atmospheres.
The connections to the mains electricity supply, installation, wire gauge and conduits will be carried out in keeping with Directives and specific current regulations. The installation of a specific mains switch for sound installation is recommended.
