When it comes to professional audio, true excellence isn’t just about power. It's about precision, reliability and sonic integrity.
Founded in the UK in 2003 by a team of experienced audio engineers, Linea Research has quietly earned a reputation among industry insiders as the Rolls Royce of Power Amplifiers. While their name might not yet be familiar to everyone in the trade, those who know, know. And, once you hear their systems in action, you’ll understand why.
Who Are Linea Research?
Linea Research was founded by experienced audio engineers with decades of combined experience in designing high-performance amplification and digital signal processing for live sound and installed systems. Their mission was simple: to deliver uncompromising audio quality with products that make life easier for the audio engineer, through intelligent design and meticulous engineering.
Every Linea Research amplifier is designed and built in the UK, combining cutting-edge DSP technology with exceptionally efficient power stages. Their engineering philosophy prioritises clarity, consistency and control, values that have made them a trusted choice for touring companies, high-end venues and integrators around the world.
What Makes Linea Research Different?
They stand apart because of the way they approach amplifier design. Their products are not built to chase specs on paper, they’re built to deliver the most transparent, accurate and reliable performance possible.
Some of their key strengths include:
Accurate Power Ratings: Thanks to premium raw components, optimised design and clever DSP algorithm, the watts per channel power ratings advertised in the product specs are not ‘transient’, ‘burst’ or ‘peak’ power figures; they are the power levels that are delivered by all channels simultaneously, even when driven with the same dense program material. This gives system designers and audio engineers complete control over the system and full confidence on the amp’s capability, without compromising on audio fidelity.
- Exceptional Sonic Purity: The amplifier design achieves ultra-low distortion and linear frequency responses across the entire operating range, meaning what goes in, comes out, exactly as intended.
- Advanced DSP Architecture: All DSP-equipped models use a high-resolution, 96KHz digital signal processor with powerful EQ, crossover, delay and limiter functions, giving engineers complete system control. Their DSP is fully developed in-house by Linea’s team, and not outsourced.
- System Engineer 8: It’s not just about hardware – Linea Research pairs its amplifiers with one of the most polished, powerful and workflow-aware control environments in pro audio: System Engineer 8 (SE8).

Made in the UK: Every Linea Research Amplifier is designed, manufactured and tested at their headquarters in Letchworth, England, ensuring unmatched quality control and attention to detail. Their commitment to engineering excellence was formally recognised in 2023 with the King’s Award for Innovation, one of the highest honours a British company can receive. This accolade reflects their pioneering work in amplifier technology and their ongoing dedication to UK-based design and manufacturing.
The Linea Research Product Families
Linea Research’s portfolio is streamlined but powerful, with each range carefully tuned for its intended application.
M Series: High Performance for Touring
The M Series is Linea Research’s flagship touring amplifier range, designed for demanding live sound environments. Available in 4 and 8 channel configurations with power ratings from 4000W to 20,000W (and don’t forget that’s ‘true’ power!), these amplifiers combine immense power with precision DSP and networking capability.
Each M Series amplifier features 96KHz DSP, FiR filters, Ethernet control via System Engineer 8, and comprehensive loudspeaker management tools, making them an ideal choice for hire production, touring rigs and large-scale PA systems.
C Series: Installed System Specialists
The C Series shares the same amplification platform and DSP power as the M series but is tailored for fixed installations. With models ranging from 4000W to 10,000W, they provide clean, efficient power and advanced control for venues, theatres, houses of worship, corporate - any environment that requires a premium power amp solution.
They’re designed for flexibility and integration, offering GPIO and Ethernet connectivity, optional Dante networking and extremely low-noise performance, perfect for precision audio in installed sound systems.
ASC48: DSP Loudspeaker Controller
For applications that require standalone processing, the ASC48 provides the same processing power and sonic quality found in Linea’s amplifiers, in a dedicated DSP controller. With 4 inputs and 9 outputs, 96KHz processing and full FiR capability, it’s the ideal tool for fine-tuning speaker systems with total precision.
Why Choose Linea Research?
Linea Research’s reputation is built purely on performance, reliability and trust among audio professionals. Their amplifiers deliver effortless headroom, transparent audio and system control that engineers can rely on time after time.
Whether you’re looking to bolster your PA stock or working on an install project, Linea Research offers the power, intelligence and integrity that truly defines high-end amplification, at an attractive price point that will no doubt be a welcome surprise.
