Ashly MA-250.4 High-Performance 4-Channel Installation Amplifier

Ashly MA250.4 Overview

Power your speakers with the latest amplifier technology with the Ashly MA-250.4, a 4-channel power amplifier that delivers 250W of power per channel. The amplifier incorporates Ashly s proprietary advanced intelligent power-sharing and ultra-efficient D-MAX amplifier technology for the cleanest and most reliable performance with lower power draw. Additionally, the MA-250.4 s multi-mode capabilities allow it to accommodate different speaker types, switchable per channel from Low Z (2, 4, and 8 ohms) to Hi Z (25, 70, or 100V).

The MA-250.4 is 2 RU and can be mounted into a standard 19" rack enclosure. The rear panel features removable Euroblock input and output connections as well as remote VC ports and switchable 80 Hz HPF and Clip Limiter on each channel. The front panel provides a volume control knob for each channel and comprehensive LED indicators for levels and amplifier status.

• Advanced Artificially Intelligent Power Sharing, can share total power across 4 channels

• Multi-mode operation can select Low Z (2/4/8 ohms) or 25/70/100V per channel
• SailFlow Directed fan cooling system
• 2 RU rack mountable
• 4 / 8 channel models
• 250W per channel
• Channel pairs can be bridged
• Front-panel volume and power controls with security lock-out
• Front-panel LED indicators for Input Signal, Peak/Mute, Temp, Protect, Power, Current, Bridging, and Share modes
• 80 Hz HPF & Limiter switch for each channel
• Remote VC ports for each channel
• Remote Standby port with selectable polarity

AI Power Sharing

Advanced intelligent power sharing dynamically distributes power to channels where needed and adapts to varying conditions. Power sharing allows the amplifier to balance power between channels to match asymmetrical speaker loads. The advanced AI-based power sharing picks up where other amplifiers leave off by intelligently and automatically adapting to your varying power demands.

Ultra-High Efficiency

You can operate as many as any three MA amps on a single 20A service. Ashly optimized active air cooling using a newly developed SailFlow design, which moves the air along a selective path, to where it s needed most. Coupled with the new Ashly-engineered ultra-high-speed switching power-supply, the use of high-speed, lossless Silicone-Carbide switches, and intelligent power management, the end-result is nothing short of stunning.

Multi-Mode Operation

With selectable multi-mode operation, the MA Series fits a wider range of applications than most other amplifiers

• In multi-zone, multi-use configurations, the MA-250.4 is truly unbeatable. Taken individually or in bridged mode, the amplifier can supply 250W for a single channel (500W in bridge mode and even more when power sharing is engaged) in low Z (2, 4, and 8 ohms) or constant voltage (25/70 or 100V) which can be selected per channel
• The amplifier is designed to excel in performance installations, such as theaters, school auditoriums, and houses of worship
• Select 25, 70, and 100V operation and the MA-250.4 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
