Product Description
Ashly MA500.4 Four-Channel Multi-Mode Power Amplifier 4 x 500W
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.
OVERVIEW
The MA Series Is Ashly’s groundbreaking new amplifier platform that redefines efficiency, performance and reliability. MA incorporates Ashly’s proprietary Advanced, Intelligent Power-sharing, and its Ultra-efficient D-MAX amplifier technology for clean & reliable performance with lower power draw. In addition, MAs multi-mode capabilities allow it to accommodate different speaker types, switchable per channel from Low Z (2, 4 & 8 Ohms) to Hi Z (25, 70 or 100V).
All MA Series models are 2RU 19” rack-mountable and feature removeable Euroblock Input and Output connections, plus remote VC ports and switchable 80Hz HPF and Clip Limiter on each channel. The front panel provides a volume control knob for each channel and a Power Standby switch both of which may be locked to prevent unauthorized user access (via a rear-panel switch) and comprehensive LED indicators for levels and amplifier status. The MA Series is designed for ultimate flexibility to suit a range of applications from Performance installations such as HoW, School Auditorium & theaters to multi-zone commercial applications such as retail stores, restaurant/bar & hotels.
