THE ULTIMATE PROTECTION

The CM90 Smart Series, featuring unique Dynamic Active Tracking filter technology, offers the most comprehensive active filtering combined with spike and surge protection for all sensitive IC chip technology on the market. Its benefits include reducing or eliminating error codes, file corruption, system hangs, and programming glitches — ensuring stable and reliable performance across devices.

Originally designed to fit neatly within a wall cavity behind a power point, its applications have expanded to boats, caravans, rooftops, and behind large screens. This versatility is made possible by its slimline, fire-retardant housing, which makes it ideal for installation in space-constrained environments.

The Thor SmartBrain not only protects from surges — it also filters and cleans electrical frequency noise, delivering unbeatable sound and video quality. Enjoy a truer AV experience with sharper picture quality and purer sound. It can also enhance computer gaming speeds and help prevent internet dropouts.

INSIDE THE SMARTBRAIN

SmartBrain uses premium Dynamic Active Tracking filter technology, a unique system that provides the highest level of noise filtration available. It shields up to 70% more frequencies compared to standard filters, giving it the best chance of effectively “cleaning” electrical noise.

Unlike conventional filters that only work at the crest of the sine wave, this active filter operates across both the upward and downward curves of the wave — capturing and removing unwanted frequencies that could otherwise interfere with sensitive electronic devices.

Riley ★★★★★

Installed one of these in my home theater setup and the Dynamic Active Tracking filter immediately cleaned up a persistent hum I had from my amp. Feels solidly built, and the cavity mount design made for a clean install inside the wall.

Adam ★★★★★

I've had these installed in my main panel for a few months now, and the Dynamic Active Tracking filter really smoothed out my old fridge's compressor hum. The cavity mount design fit perfectly in my tight breaker box without any extra adapters needed.

Joshua ★★★★☆

Setup was straightforward once I read the instructions carefully. The Dynamic Active Tracking filter technology seems to keep my audio gear humming cleanly, though I wish the mounting brackets felt a bit sturdier. Overall, solid protection for my home theater setup.
