Four may be an even number, but a four-channel amplifier like AudioControl’s Avalon G4 might seem like an odd duck to some. With Dolby Atmos and other immersive audio formats becoming more common in the custom install market (where AudioControl, which manufactures products at its Seattle facility, has a heavy presence), however, upgrade-anxious customers will obviously need four additional amp channels to complement the company’s existing 5- and 7-channel designs.
​I might argue that 50 watts per channel is more than adequate to drive overhead speakers in an Atmos-ready home theater, but that’s just me. The Avalon G4 is rated at 230Wpc into 8 ohms and 300 Wpc into 4 ohms. Its four channels can also be bridged into two channels to deliver 600 Wpc into 8 ohms.
Features
The Avalon G4 comes in a sturdy but otherwise plain chassis that’s likely meant to be slid into a rack rather than displayed like a totem between front speakers. When it’s plugged in, red lights are visible though the openings at the top rear. Power it on and a bar of blue light illuminates the otherwise featureless front panel, and there’s blue lighting on the rear panel as well. The front light can be turned down or off if desired, but the rear ones can’t be defeated—a potential annoyance.(AudioControl says they have made a running change, with rear-panel light status now linked wth the front-panel lights.)
The analog class-H amp weighs a sturdy but manageable 38 pounds, with most of that weight in a large toroidal power transformer. Conventional class-A/B amps have peak voltage available at all times, while Class-H ones adjust the circuit supply voltage depending on the instantaneous requirements of the source material. This improves efficiency and allows the Avalon to run relatively cool. It also employs AudioControl’s LightDrive system for anti clipping protection.

The Big Clean
Chances are you probably do not think about the state of your electronic devices too often. Oh, you might think about all the upgrades you would like to make; where you would put those new tower speakers, or how a second or third subwoofer would really tame those bass modes in your room, or how much more cinematic a larger screen would be. Sure, you think about that part of your system. But how often do you think about the well-being of your system?

Bridging the Analog-Digital Gap on a Recliner
When I shopped for a motorized recliner, I rejected models with their own Internet Protocol address and built-in speakers. No need. I had already placed a smart speaker on an étagère beside the space where I had planned to put the chair. I'd have a smartphone in my hand and the room would be bathed in Wi-Fi.
