Arcam FMJ A777 7-Channel Amplifier



Having gained a world class reputation for amplifier design over thirty years, Arcam introduce the P777 multi channel amplifier for home cinema and music reproduction. Using technology honed thorough the development of dozens of award winning amplifiers, the P777 is the company’s highest performing multi channel amplifier yet.

Subtle detail is retrieved with startling realism even though the P777 is a true power house amplifier with huge output potential. Over 1.6kW of continuously available power is available to drive loudspeakers with clarity and precision and control. Substantial heat sinking and a computer controlled fan cooling system ensure it remains cool even under extreme duress with an predominantly aluminium construction ensuring chassis temperatures are kept low while electro-magnetic interference is kept away from delicate audio signals.

The Two oversize toroid power transformers feed the seven power amplifier channels with separate secondary windings for each channel. The centre channel, often the most important as it carries dialogue information, is fed from both transformers for maximum performance. “Soft Start” circuit is deployed to reduce inrush load on the incoming mains supply at switch-on with the toroid standby transformer and control circuits kept in their own aluminium enclosure for additional screening.

The P777 is one of the finest multi channel amplifiers in the world and is specifically designed for the most ardent home cinema enthusiast or advanced custom installer. Available in black or silver finish, the P777 is designed and manufactured in the UK.
