Arcam AVR550 7-Channel AV Receiver Overview

The Arcam AVR550 7-channel AV receiver, from a company dedicated for decades to audiophile ideals, incorporates some of the UK manufacturer’s best ideas and technologies into a single chassis. The oversize toroidal transformer delivers a powerful 110 watts per channel across the frequency spectrum, and the AVR550 drives audiophile-quality home cinema speaker systems to impressive levels. Dolby Atmos and DTS:X send the sound up, down and all around. Sophisticated Dirac Live room-optimization system puts the power of a custom installation into the hands of every user, tuning out phase, frequency and impulse anomalies from your speakers to your walls. You get all the controls and connections you need – including 7 HDMI inputs and 3 outputs, full 4K UHD support, and an array of assignable analog and digital inputs – and the finest aspects of separate components wrapped into a single, sonically superior package.

All about Arcam

The British audiophile company A&R Cambridge – Arcam for short -- was founded by two engineering students at Cambridge University in 1976. The company has been designing high-end audio components in the UK for decades, and audiophile-quality surround receivers for more than 20 years, including pioneering research into amplification circuitry.

Power to spare, into any load

With 110 watts per channel at 8 ohms at all audible frequencies, the seven amplifier channels can drive any modern audiophile stereo or surround system to room-filling volumes. An oversized toroidal power transformer makes sure that the AVR550 has the reserves to meet any sonic needs. As Glenn Young said in his Secrets of Home Theater and High Fidelity review of the AVR550, “(It) just plain sounds better than other AVRs I’ve heard. The best endorsement I can give this receiver is to say that I bought it.”

Adapts to your listening environment and tastes

Most modern high-end AV receivers include circuitry to automatically tune the system to the room and the speakers for maximum performance. But only Arcam puts the power in your hands. Download the Dirac Live software from Arcam’s website (free, for Mac and PC), plug the included mic and USB soundcard into your computer, take measurements at several listening positions, and the software adjusts the output for frequency, phase and impulse differences – and shows you exactly what it’s doing on your computer screen. Simply accept the alterations as they appear, or tweak to your tastes and heart’s content.

Your complete control center

With a full array of digital and analog inputs, Ethernet, and seven HDMI inputs plus 3 outputs (with full 4K Ultra HD and HDR support), the AVR550 can handle every audio and video source in today’s complicated world. You get Dolby Atmos and DTS:X decoding for the most immersive cinematic effects, with 5.1.2 (that’s front L-R-C, surround L-R, 1 subwoofer and 2 height channels) out of the box, and full 7.1.4 decoding by adding external amplifiers such as Arcam’s own P429 4-channel model.

App adaptable

Arcam’s MusicLife app (free, for iPhone and iPad) puts control of the receiver in the palm of your hand, including music streaming from home network, Internet radio or online music services. The AVR550 is Spotify Connect enabled, includes a full-function handheld remote, and can be integrated with smart-home systems from Crestron, Control4 and others.
