Apocalypse ATOM-400.4 PRO | 400 Watt 4-channel amplifier

Meet the newest four-channel in the Atom PRO series — the perfect choice for systems running multiple speakers and demanding wiring configurations all the way down to 1 Ohm. Most amplifiers on the market simply can't handle this: the vast majority of four-channels are only rated to run 2 Ohm per channel. The Atom PRO changes the game, letting you effortlessly wire setups like three pairs of speakers at a combined 1.33 Ohm load — and making your life a whole lot easier in the process.

The Atom PRO line is the perfect balance of size and output. This amplifier not only saves precious space and fits into the most challenging installations — it delivers maximum power for your money with rock-solid stability at low impedance.

And the sound? This isn't just competitive with Class AB — it's on the same level. In our blind tests, even the most seasoned competition judges couldn't tell the difference. That is what makes this amplifier truly one of a kind.
