User manual ARCAM FMJ P7

[. . . ] This handbook has been designed to give you all the information you need to install, connect, set up and use the Arcam FMJ P7 Multichannel Power Amplifier. It may be that the P7 has been installed and set up as part of your Hi-Fi or home cinema installation by a qualified Arcam dealer. In this case, you may wish to skip the sections of this handbook dealing with installation and setting up the unit. Use the Contents list to guide you to the relevant sections. [. . . ] AV8) Right surround Right rear surround Right front Centre Left front Left Left surround surround rear The speakers should be connected to the loudspeaker terminals, as per the correct input signal. In other words, the Centre channel speaker should be connected to the module that is being fed the signal for the Centre channel, and so on, for all the channels. As with all speaker connections, ensure that polarity is maintained when connecting the speakers (i. To bi-wire or bi-amplify your speakers, refer to the section towards the end of this handbook where diagrams are provided. If you are unsure as to how your system should be connected, or need advice on bi-amping, please consult your Arcam dealer. The appliance is normally supplied with a moulded mains plug already fitted to the lead. If for any reason the plug needs to be removed, it must be disposed of immediately and securely, as it is a potential shock hazard when inserted into the mains socket. Should you require a new mains lead, contact your Arcam dealer. Check that the plug supplied with the unit fits your supply and that your mains supply voltage agrees with the voltage setting (100V, 115V or 230V) indicated on the rear panel of the unit. If your mains supply voltage or mains plug is different, consult your Arcam dealer or Arcam Customer Support on +44 (0)1223 203200. Push the plug (high current IEC line socket) of the power cable supplied with the unit into the POWER INLET socket in the back of the unit. The P7 has been designed so that a standard-rating IEC cable (which has insufficient current rating) cannot be plugged into the P7. Only high current power cables can be connected. Put the plug on the other end of the cable into your power supply socket and switch the socket on. The P7 front panel has a single control: a centrally located power on/off button. Once the relevant connections have been made, the P7 can be switched on using the central button on the front panel. Note that the modules are turned on individually to stagger the surge created when a powerful amplifier is switched on (i. This reduces the surge current drawn from the domestic power supply. It is recommended that you switch on your pre-amp or controller before powering up the P7 power amp. Normal powering up is indicated by the following sequence of front panel LED indicators: 1. On pressing the power switch, all LEDs turn red. Connect another module, or one channel of a separate power amp, to the other pair of terminals on the speaker, so that two amplifier channels are connected to that speaker; one for low frequencies and one for high frequencies.
