Ashly MA250.4 – 4-Channel Multi-Mode Power Amplifier with Intelligent Power Sharing

The Ashly MA250.4 is a next-generation 4-channel power amplifier designed for ultimate flexibility, efficiency, and performance in professional audio installations. Featuring Ashly’s proprietary D-MAX™ Class D amplifier technology and Advanced Intelligent Power Sharing, this amplifier delivers up to 250W per channel (or 500W bridged), ensuring clean, reliable power with significantly reduced energy consumption.

What sets the MA250.4 apart is its multi-mode operation, allowing each channel to be independently configured for Low Z (2, 4, 8 Ohms) or Hi Z (25V, 70V, or 100V) output.
