[. . . ] Multichannel Power Amplifier 2 Using this handbook 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.

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. e. 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 biamping, please consult your Arcam dealer. I CONNECTING TO A POWER SUPPLY WRONG PLUG? 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 203203. MAINS LEAD 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. PLUGGING IN 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. Put the plug on the other end of the cable into your power supply socket and switch the socket on. 7 Operating your P7 P7 MULTICHANNEL POWER AMPLIFIER 1 2 3 4 5 6 7 FRONT PANEL LAYOUT The P7 front panel has a single control: a centrally located power on/off button. OPERATING PROCEDURE Once the relevant connections have been made, the P7 can be switched on using the central button on the front panel. POWER Switches the unit on and off. Note that the modules are turned on individually to stagger the surge created when a powerful amplifier is switched on (i. e. This reduces the surge current drawn from the domestic power supply. SWITCHING ON 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. The LEDs continue turning amber from the centre to the edges in pairs, with intervals of approximately one second. The LEDs continue turning green from the centre to the edges in pairs, along with relay `clicks', with intervals of approximately one second. POWER/STATUS LEDS A separate LED indicates the status of each of the seven channels of the P7. The LEDs cycle through red, orange, then green to indicate the status from powered-up (initialised), stabilised and active respectively. All LEDs are off in standby mode. If the LEDs do not follow this sequence when the P7 is powered up, or behave abnormally at any time during use, then consult the table of `Fault status indicators' on page 11 to discover why the amplifier is in protection mode. NOTE: It is recommended that if the unit is switched off, then it should not be switched on again for at least 20 seconds from when it was turned off. [. . . ] An over temperature fault has reoccurred on one or more channels, or the power transformers have overheated within 12 seconds of a previous over temperature fault clearance. A DC offset fault occurred on one or more channels while attempting to clear a multiple over temperature fault. A short circuit fault occurred on one or more channels while attempting to clear a multiple over temperature fault. During power up or normal operation, one or more LEDs are flashing red, with the remaining LEDs NOT solid red During power up or normal operation, one or more LEDs are flashing amber During power up or normal operation, one LED is flashing amber, with the remaining LEDs solid red During power up or normal operation, all the LEDs are flashing amber During normal operation, all the LEDs are solid red The amplifer mutes the channel with the fault and its paired channel. The amplifier stays in this state for up to half-a-second or until the fault clears (whichever is sooner). [. . . ]
