Linea Research 44m20 – Class D Power Amplifier Hire
About this product
The Linea Research 44M20 is one of the most powerful and technically advanced four-channel touring amplifiers available anywhere in the world — and it's built right here in the UK. Delivering 4 × 5,000W at 2 ohms with all channels driven simultaneously, the 44M20 represents the pinnacle of professional amplifier technology for live sound. Available for Class D power amplifier hire across Northamptonshire, the East Midlands and the wider UK through Northants Event Solutions.
Used at the highest levels of festival and touring production globally, the Linea Research 44M20 is the amplifier serious sound engineers specify when maximum power, precision and reliability are non-negotiable. Fully integrated 96kHz DSP on all inputs and outputs provides LIR linear phase crossover filtering, the VX Limiter suite (Peak, RMS, Excursion and multi-band limiting), parametric EQ, delay and grouping — all controlled via Ethernet network through the System Engineer PC application. Analogue and AES3 inputs are standard, with optional Dante/AES67 digital network audio. Over-designed high-capacity switch mode power supply delivers the full rated power into 2 ohms across all four channels simultaneously — not a burst or peak figure. Auto-sensing PSU accepts 85–240V for international touring use. Whether driving subwoofers, main PA systems or complex multi-way configurations, the 44M20 delivers without compromise. Commonly deployed as matched amplification for our Martin Audio and JBL cabinet hire packages. System Engineer DSP programming and Ethernet network setup available as part of our fully managed technical hire service.
