AudioControl Concert AVR-1 review

You may not have heard of AudioControl, but it is a sizeable 30-year-old company and a big hit back in its native US of A. The company is probably most famous for its in-car equipment but it has a growing reputation for home theatre gear; often great value and often selected by installers for classy home cinemas.

The company's marketing and attitude is a bit loud, a bit lairy and a bit in-yer-face, but they are American so we expect that. The Concert AVR-1 is the latest flagship AV receiver – or as AudioControl like to call it, its premium Home Theater Platform. By the time it has hit UK shores, it retails for a not inconsiderable £6,000 plus a remote control.

What, no remote as standard? Correct, because AudioControl believes that the very best remote is a dedicated multi-function device such as the Philips Pronto (£1,150) for which the company supplies dedicated interface software.

At nearly £7,500 we are getting into serious territory, well above the top-end Pioneer, Denon, and Yamaha models and beginning to encroach on the bottom end of Krell, Lexicon and Anthem territory. Serious stuff.

Starting from the outside, the AVR-1 is about as subtle as a motorway pile-up. It's huge, monstrously heavy, and the cosmetics are straight out of the McIntosh bling school of design. The fascia is black glass with enough blue LEDs to read a book by at ten paces, and the dot-matrix style LCD display powers up with a full width/full height company logo like a Las Vegas slot machine.

The casework looks like an exercise in structural engineering, particularly with its rack-mount cheeks in place, and the rear panel offers speaker binding posts capable of accepting cables up to steel-shipping hawser size.

Connectivity is faultless, with a good number of pretty much every input/output you could need for the most serious AV set-up.

The features list is certainly not left wanting, with full decoding for all the regular Dolby and DTS formats over HDMI; full network access via Ethernet; USB with streaming control; 5-in 2-out HDMI sockets, and a full set of installer features. These include multizone outputs, 12V triggers, IR repeaters and RS232 integration.

There is nothing in the features set that would not be trumped by a £2K Onkyo, but AudioControl's big push is premium sound quality derived from its innovative Class H amplifier topology.

Class H amplifiers take the idea of stepped voltage rails further by offering an infinitely variable power-supply voltage. It's a complex design in terms of engineering, but it allows the power amps to run at optimum efficiency by tracking the input signal and adjusting the voltage rail output accordingly in real time.

Under idling or low volume conditions, the AVR-1 ticks over, running cool and merely sipping a few watts from your mains supply. Crank up the volume or get a big program demand such as an explosion and the power supply voltage raises instantly to ensure massive dynamic headroom.

The upshot is an amp that only draws as much current from the wall as is required, wasting very little in heat. That's green credentials. Of a sort.

Basic menu

As the Pronto and set-up mic both failed to turn up with the review sample, I had to resort to the front panel controls to run the setup; the auto-set-up feature only provides very basic filtering room EQ anyway, so I stuck to manual rather than risk using an uncalibrated mic.

Unfortunately, AudioControl's menu-driven interface is a bit clunky and I do miss the pretty-pictures and interactive GUIs of other top-notch designs.

The left-right, up-down and select keys on the front panel don't necessary drive the menus in the direction you expect, but generally set-up wasn't too painful even without the Pronto.

Let me get the bad bit out the way first by stating that our sample AVR-1 was a bit 'buggy'. It's Insect House at London Zoo buggy, in fact.

Chances are that by the time you read this many of the issues will be sorted by firmware updates, but I had a full gamut of aggro, including HDMI syncing issues, getting video from one input and audio from another, long pauses of silence after changing sources, a jumpy volume control, and occasionally no sound at all. It does make you realise just how slick the big Japanese manufacturers are when they release a complex product like a multi-function AV receiver.

Thankfully, the bugs tended to be set-up and control related, meaning that when the AVR-1 was doing its thing it really got down to business with unfettered aplomb.
