Ashly CA 1.52 – Two-Channel Install Power Amplifier

Available in 2 and 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 and 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.

“State-of-the art” is an overused term when it comes to amplifier technology. With the CA Series, Ashly achieved it by starting from scratch instead of just adding a few improvements to an existing model. They took advantage of components that didn’t even exist a couple of years ago. They figured out how to boost efficiency, speed up switching, and stay extra cool without gale force fans. This 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! Along with increased efficiency, DPFC allows LEEDs qualification.

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. Ashly’s unique SailFlow™ architecture 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.
