Rated 4.9 (99 reviews)
The Linea Research 44 M6 is a 4-channel touring-grade power amplifier delivering 1,500W per channel at 4 Ohms – all channels simultaneously, with no burst or peak inflation. Built around 96kHz DSP with LIR linear phase crossover filters, the M6 offers precise loudspeaker management in a compact 2U chassis. Independently verified as 7-10% more efficient than comparable amplifiers, it’s a strong choice for production companies and rental houses looking to reduce power draw without sacrificing headroom.
