The Linea Research 48 M3 is an 8-channel power amplifier built for touring and installed live sound applications where channel count matters more than raw power per output. Delivering 400W per channel at 4 Ohms – all eight channels simultaneously – it suits distributed speaker systems, delay fills, and monitor rigs. With onboard 96kHz DSP and Linea Research’s efficient Class D topology, the 48 M3 packs serious processing and amplification into a compact 2U chassis.
