“State-of-the art” is an overused term when it comes to amplifier technology. With our CA Series, we achieved it by starting from scratch instead of just adding a few improvements to an existing model. We took advantage of components that didn’t even exist a couple of years ago. We figured out how to boost efficiency, speed up switching, and stay extra cool without gale force fans. We created the most efficient high-wattage amplifier yet.

New D-MAX™ design lets you run multiple CA’s on one 20 A service.

Showtime. You power up 12,000 watts of amplifiers. OOPS! Popped the breaker on the only 20-amp line in this side of the building.
Traditionally, big amps have been gluttons for more juice than one 20A line can put out.
Ashly’s all-new, proprietary D-MAX technology brings together smart, cutting-edge amplifier design, a brand-new ultra-fast switching power supply with silicon dioxide semiconductors and diodes, and intelligent power management to deliver ultimate efficiency. You can operate two of CA 1.54s (6,000W total each) on a single 20-amp service! That’s higher efficiency than any other currently available amp we’ve tested! As this chart shows, Two of our leading competitor’s amps exceeds 20 amps…while providing LESS power to speakers than our CA-1.54!
And along with increased efficiency, DPFC allows LEEDs qualification.

When current and voltage are exactly in phase, current demand is reduced and efficiency increased. Dynamic Power Factor Correction tracks current continuously to maintain accurate monitoring & control.

Silicon Carbide semiconductors boost both speed and efficiency.

Another important part of Dynamic Power Factor Correction is our use of a new cutting-edge semiconductor that is significantly faster than the old-school pure silicon that our competitors use.
Traditional silicon semiconductors don’t shut off instantly. They have a lag time called “switching loss”, leading to a residual tail current (red portions in the drawing at left). From an audio quality standpoint, this makes for a sloppier, less precise sound; from an efficiency standpoint it sucks up unnecessary power.

Instead, we are pioneering the use of Silicon Carbide (SiC) semiconductors. They have unique electrical characteristics that render them able to switch on and off far faster than conventional silicon. The result is an amplifier design that’s faster ( thus better audio fidelity) AND more efficient.

CA amps run cool without needing heavy heat sinks and noisy fans.

Power amplifiers need cooling. In most amps, heat-reducing air flow takes a convoluted path in and around internal components. Front to back, back-to-front-side-to-side…those nice perforated grilles look simple…until you look inside the amp and see the helter-skelter air flow (see drawing below left)

We didn’t want cooling air to just wander around inside the CA chassis, so we came up with our unique SailFlow™ architecture (right drawing below). It directs internal airflow strictly over the areas that generate the most heat, rather than arbitrarily over the whole amp. This keeps the already highly efficient CA Series even cooler and assures reliable, stable operation, even under heavy loads.

Stable operation at 0.2 ohms (0.2Ω) No, that’s not a misprint.

For performance spaces, the CA Series can push hard and keep on pushing. Play it loud? No problem. Big subs? Bring ‘em on! CA can take it down to 2 Ohms without missing a beat (and without a drop- off in power). Run up to SIXTEEN 8-ohm loudspeakers from a single 4-channel CA amplifier.In commercial installations CA can deliver 70V and 100V power with no reconfiguration required. And choice of both XLR and Euroblock connectivity make the CA at home just about anywhere.

Technical Details of the Most Efficient Line of Power Amps Yet.

Available in 2 & 4-channel configurations with 500W, 1,000W or 1,500W per channel, there’s a CA that’s right for your project. CA amps are designed to excel in Performance Installations, such as theaters, school auditoriums and Houses of Worship. Power-hungry sub-woofers? No problem. CA does 2 Ohms lying down.

However, with 70 & 100V direct-drive capability and more integration-friendly features than you’d typically find on many amplifiers, they are also right at home in commercial installations. Push them hard. They can take it.
CA amps can drive longer and louder than amps twice their rated power and cost. Powerful. Clean. Reliable.
