The Arcam P777 is a powerful multi-channel power amplifier designed for high-performance audio in both home cinema and music reproduction. It features advanced engineering with a focus on clarity, precision, and control, utilizing Sanken output devices and thermal management techniques derived from Arcam's extensive experience in amplifier design. The P777 delivers 150 watts per channel at 8 ohms and 230 watts per channel at 4 ohms, capable of handling demanding loudspeakers and program material. With a total output exceeding 1.6 kW, it ensures robust performance even under heavy loads. The construction includes a predominantly aluminum chassis, which helps minimize electromagnetic interference while maintaining lower temperatures through its substantial heat sinking and controlled fan cooling system. The amplifier connects with balanced (XLR) and unbalanced (RCA) inputs, and it offers comprehensive protection circuitry including DC offset and thermal protection. The design also features twin toroidal power transformers for efficient power distribution, and a soft start mechanism that mitigates inrush current at power-up. Measuring 435mm wide, 460mm deep, and 185mm high, the P777 weighs approximately 31kg, making it a solid choice for serious audio enthusiasts and custom installations alike.
