Arcam PA720 7-channel power amplifier
Seven channels of solid power
If you're building a home theater sound system, the Arcam PA720 can feed your speakers the watts they need. It produces 100 watts times seven channels, for your front left, right, and center speakers, plus four more surround and/or effects speakers. Now you can immerse yourself completely in movie dialogue, sound effects, and music.
Versatile Class G amplifier
The engineers who designed the PA720 wanted it to provide the right amount of power at the right time, so your entertainment choices sound exactly as they should. That's why they chose a Class G amplifier design, which uses 20 watts of Class A circuitry for standard-level signals, then kicks in a higher-voltage power supply for more demanding dynamic peaks. And it does it without adding any crossover distortion or noise.
Convenient connections
The PA720 offers unbalanced RCA and balanced XLR inputs for connecting to an A/V preamp. An RS232 input allows third-party remote control, and an Ethernet port lets you connect to the internet and works with home automation. There's 12-volt trigger input and output for remote turn-on, and a USB Type-A port for firmware updates.
