Integrated system:
The main units include in only one module the power supply, a preamplifier-adaptor of the level of audio and the
telecontrol unit (auto on / auto off of external audio sources when disconnecting all the controls). The telecontrol (auto on) will only be effective if this audio source doesn't have the stand-by option. The audio source needs to be connected to the main unit's socket. (The telecontrol acts through wire 15 of the left channel).

Equivalent products:
The diagramme can be carried out exactly the same as for the P4018SE P4018ME and P4018SM.

Cable to be used:
The connection to the distribution line can be carried out using cables, Mod. P9930 (for two mono / stereo channel, with or without scan)

Material used in the example:
1 P4018MP3 main unit - 1 P4075 sound source connector

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.
