About the Linea Research 48M Series Amplifiers
The Linea Research 48M Series Amplifiers are a range of eight-channel Class D units spanning 3,000 to 20,000 watts RMS total output, with individual channel power from 400 W to 1,250 W. Precise 96 kHz digital signal processing, powerful grouping and multi-layer EQ, and an Ethernet network port for system operation and monitoring sit alongside analogue, AES3 and optional Dante or AES67 digital audio inputs. An 85 V to 240 V auto-sensing power supply ensures full output can be delivered into 2 ohms with all channels driven. Select models also accept 48 kHz and 96 kHz FIR files via System Engineer software. The entire range is designed and manufactured in the UK by Linea Research.
Linea Research 48M Series Amplifiers — buyer FAQs
What is the Linea Research 48M Series and how many channels does it provide?
The Linea Research 48M Series is a range of eight-channel Class D power amplifiers covering models from 400 W to 1,250 W per channel, giving a total RMS output of 3,000 to 20,000 watts depending on the model. The range includes variants such as the 48M03, 48M06, 48M10 and 48M20, allowing users to select the output level that suits their system requirements.
What DSP and connectivity options does the 48M Series include?
Each 48M Series amplifier incorporates 96 kHz digital signal processing with powerful grouping and multi-layer EQ, and accepts both 48 kHz and 96 kHz FIR files via System Engineer software on compatible models. Input options include analogue, AES3 and optional Dante or AES67 digital audio, and an Ethernet port enables system operation and monitoring across a network.
What power supply specification does the 48M Series use?
The 48M Series uses an over-designed switch-mode power supply with auto-sensing from 85 V to 240 V. The high-capacity design is specified to deliver full rated power into 2 ohms with all eight channels driven simultaneously, maintaining efficiency across varying load conditions.
Who makes the Linea Research 48M Series amplifiers?
The 48M Series is made by Linea Research, a manufacturer that designs and engineers its products entirely in-house and produces them in the UK. Within the range, model numbers indicate output level, with the 48M03 at the lower end and the 48M20 at the top, all sharing the same eight-channel Class D architecture and 96 kHz DSP platform.
What should I check when buying a used Linea Research 48M Series amplifier?
Confirm which specific model you are buying (48M03, 48M06, 48M10 or 48M20) as output power varies significantly across the range. Check whether optional Dante or AES67 networking is fitted, since this affects connectivity in digital audio systems.
