Linea Research 44M20 4x5000W DSP Amplifier

The Linea Research 44M20 represents the absolute benchmark in high-power, high-density 4-channel touring power amplification. Engineered and manufactured in the United Kingdom, the 44M20 combines a massive 20,000 Watts of continuous RMS power output with state-of-the-art 96kHz DSP, native Dante™ audio networking, and advanced system diagnostics—all housed within a rugged, road-ready 2RU chassis.

Designed specifically for demanding touring sound reinforcement, high-output stadium PA systems, large festival stages, and premium performance venues, the 44M20 delivers uncompromising sonic purity, massive headroom, and absolute thermal stability under maximum load conditions across 2 Ohm, 4 Ohm, and 8 Ohm loudspeaker configurations.

Why Systems Integrators & Production Houses Specify Linea Research

When powering mission-critical line array systems, heavy subwoofer arrays, and large-scale point-source rigs, high-end touring engineers and system designers choose the Linea Research 44M20 for several definitive technical reasons:

Unrivaled Power Density 4 x 5,000 Watts

The 44M20 is capable of delivering an astounding $5,000\text{W}$ per channel simultaneously into 2 Ohms or 4 Ohms ($3,000\text{W}$ into 8 Ohms). This massive power density allows production companies to replace multiple legacy 2RU power amplifiers with a single 44M20 unit, dramatically reducing amplifier rack weight, truck space, and venue power consumption. 

Architectural 96kHz LICC™ DSP Engine

Integrated directly into the input and output processing chain is Linea’s high-performance 96kHz DSP. Each channel features ultra-clean linear-phase FIR crossovers, 8th-order IIR parametric EQ, high-pass and low-pass filtering, up to 1.3 seconds of delay, and Linea's proprietary multi-stage Virtual Crossover (VX) limiters to maximize speaker driver protection without introducing audible dynamic compression. 

Native Dante™ & Automatic Input Failover

Featuring native 96kHz Dante™ network connectivity built straight into the back panel, the 44M20 routes digital audio cleanly over standard Ethernet networks. For mission-critical live events, the amplifier supports automated priority input switching between Dante, AES3 digital, and balanced analog inputs to ensure absolute performance redundancy. 

Active Power Factor Correction (PFC)

Extreme live sound environments often suffer from fluctuating voltage levels, long cable runs, or dirty generator power. The 44M20’s heavy-duty Switch Mode Power Supply features active PFC, ensuring constant, unthrottled burst power and maximum current efficiency regardless of local mains supply variations.

Comprehensive Telemetry via System Engineer PC App

Networked via Ethernet, the 44M20 integrates seamlessly into Linea's intuitive System Engineer software. Sound engineers can monitor output voltages, thermal headroom, mains current draw, load impedance, and real-time limiter activity across entire amplifier networks from a single control position.
