Multi-channel Class D amplifier platforms with onboard DSP, covering Linea Research’s C and M series and NEXO’s NXAMP and nanoNXAMP amplifier-controllers. Four and eight channel models dominate, with Dante network audio available across much of the Linea Research range and on the nanoNXAMP4-D, and power classes scaling from compact install units to the 44M20 and 48M20 touring amplifiers.

The C and M split in the Linea Research catalogue is the first thing to understand: C series units are aimed at fixed installation while M series models are built for touring and portable racks, and both carry loudspeaker processing on every channel. NEXO’s NXAMP platform is different, pairing amplification with NEXO’s own controller presets, and it is the correct drive for NEXO cabinets rather than a generic alternative. Across the category, weigh channel count against per-channel power, confirm the input formats you need across Dante, AES and analogue, and remember that a DSP amplifier replaces a separate system processor in most designs, which changes the budget comparison. Networked control also matters at scale; dedicated system controllers such as the NSC series manage larger amplifier fleets.

Trade accounts suit contractors specifying these across multiple jobs, and we can advise on matching amplifier platforms to specific cabinet inventories.
