Ashly MA500.4

Ashly MA500.4 Ultra-High Efficiency 4 channel Power Amplifier

The Ashly MA-500.4 power amplifier blends industrial strength with advanced power management, offering four 500W channels, power sharing capabilities (up to 1,000W per channel), and bridging options.

Featuring D-MAX technology for clean and rapid power switching, it streamlines power sharing via AI, reducing technician workload. The amplifier’s extensive multimode switching accommodates various speakers, with lo- and hi-Z switching for diverse impedance and voltage settings. It includes 80Hz highpass filters, clip limiters, and front-facing reference LEDs for efficient performance optimization. Despite its compact size, the MA-500.4 impresses with its muscular scope and intelligent design, making it an ideal, unobtrusive power solution for auditoriums, houses of worship, retail spaces, hotels, and more, thanks to its slim 2RU 19-inch rack-mountable housing.

The MA Series represents a new pinnacle in power amps. We can proudly and confidently state that the MA Series is the best amplifier that we’ve ever built (and perhaps that anyone has ever built). Ashly’s proprietary D-MAX™ technology (first implemented in the CA Series) takes Class D performance and efficiency to a whole new level. By starting with a clean slate, our engineers were able to throw away the old rule book and apply cutting-edge design practices and state-of-the-art components to achieve something truly unique.

Power amp users have become more familiar with and have even demanded power-sharing in recent years- the feature that allows the amplifier to balance power between channels to match asymmetrical speaker loads. That can prove useful when designing systems. Though there are other amplifiers that incorporate power-sharing, most of these require DSP to be set up in the proper configuration, and those that don’t are very limited in the way they can work.

The MA Series is by far the most efficient amp we’ve built and tested thus far. The pay-off is less heat, lower noise and distortion, more stable operation, and greater reliability. In fact, they run so cool, that bulky heat sinks found in most other amplifiers are no longer required. Instead, we were able to optimize active air cooling using our newly developed SailFlow™ design, which moves the air along a selective path, to where it’s needed most. Coupled with our new Ashly-engineered ultra-high-speed switching power-supply, the use of high-speed, lossless Silicon-Carbide switches and intelligent power management, the end-result is nothing short of stunning.

All the transient impact and spatial detail of your sound is preserved, and your speakers will never be happier. Light-weight and power-efficient, MA will never pull more power than your wall outlet delivers. No more worry about driving speakers to the brink of destruction or tripping breakers. For example, you can operate as many as three of the MA500.8s (12,000W total) on a single 20A service! That’s more efficient than any other currently available amp we’ve tested! Lastly, this translates into power cost savings as well, since MA’s do more work while drawing less power than other amplifiers, lowering user’s electrical bills and HVAC requirements.

With selectable Multi-mode operation per channel, the MA Series fits a wider range of applications than most other amplifiers. In multi-zone, multi-use configurations, the MA is truly unbeatable. Taken individually or in bridged mode, MAs can supply from 250W to 1,000W for a single channel (even more when power sharing is engaged) in low Z (2, 4 & 8 Ohms) or constant voltage (25/70 or 100V) which can be selected per channel. MA amps are designed to excel in performance installations, such as theaters, school auditoriums and Houses of Worship.

Power-hungry sub-woofers? No problem. MA does 2 Ohms lying down. However, with multi-mode operation, you can also select 25, 70 & 100V operation. MA also has more integration-friendly features than you’d typically find on many amplifiers, and with 4 and 8-channel models to choose from they are also right at home in the most demanding multi-zone commercial installations.

Available in 4 & 8-channel configurations with 250W or 500W per channel, there’s an MA that’s right for your project. Push them hard. They can take it. MA amps can drive longer and louder than amps twice their rated power and cost. Powerful. Clean. Reliable. That’s Ashly’s MA Series.
