About the Linea Research 44M Series Amplifiers
The Linea Research 44M Series delivers four channels of Class D amplification across three models, the 44M06, 44M10 and 44M20, with total RMS output ranging from 6,000 to 20,000 watts. All models feature an 85V to 240V auto-sensing switch mode power supply capable of delivering full rated power into 2 ohms with all channels driven. Onboard 96kHz digital signal processing includes powerful grouping, multi-layer EQ and support for FIR files via System Engineer on certain models. Audio connectivity covers analogue, AES3 and optional Dante or AES67 digital network audio, with Ethernet provided for system operation and monitoring. The full front panel user interface and UK-designed-and-manufactured construction complete the feature set.
Linea Research 44M Series Amplifiers — buyer FAQs
What models make up the Linea Research 44M Series?
The 44M Series comprises three models: the 44M06, 44M10 and 44M20. All three deliver four channels of Class D amplification, with per-channel output varying by model. The 44M06 produces up to 1,500W per channel, the 44M10 up to 2,500W, and the 44M20 up to 5,000W, giving a total RMS range across the series of 6,000 to 20,000 watts.
Who makes the 44M Series amplifiers and where are they built?
The 44M Series is made by Linea Research. All models are fully designed, engineered and manufactured in the UK by Linea Research, meaning the hardware, power supply and DSP architecture are developed in-house rather than assembled from third-party platforms.
What DSP and connectivity options does the 44M Series offer?
Every 44M Series amplifier includes 96kHz digital signal processing with grouping, multi-layer EQ and a full front panel interface. Audio inputs cover analogue and AES3 as standard, with Dante and AES67 digital network audio available as an option. Ethernet is built in for system operation and monitoring, and certain models accept 48kHz and 96kHz FIR files via the System Engineer software.
What impedance loads can a second-hand Linea Research 44M Series amplifier drive?
All three models are rated at 2, 4 and 8 ohms, and also support 70V and 100V distributed audio systems. The 44M20, for example, delivers 5,000W per channel at 2 ohms and 3,500W or 5,000W into 70V or 100V lines. The auto-sensing power supply covers 85V to 240V mains, allowing operation across different regions without manual switching.
What should I check when buying a used Linea Research 44M Series amplifier?
Confirm which specific model you are buying (44M06, 44M10 or 44M20) as power ratings differ substantially between them. Check whether optional Dante or AES67 network audio is fitted, and verify that all four output channels are functional. Used units sold on 10K Used carry a 21-day warranty covering major functional faults; full details are in the buying guide at https://www.10kused.com/used-av-equipment-guide/.
