Loudspeaker Management Processors (DSP)

Loudspeaker management processors and install DSP from Martin Audio, NEXO, Linea Research, BSS and Biamp. This is the box between console and amplifiers: crossovers, EQ, delay and limiting that turn a rack of amps and cabinets into a system, with Martin Audio’s DX range, the NEXO DTD controllers and the Linea Research ASC48 all offered in standard and Dante-networked versions.

Start with input and output count, the DX4.0 runs four inputs to eight outputs, which covers a stereo system with subs, fills and delays, while smaller DX models suit simpler rigs. Then decide how audio arrives: analogue is simple and robust, while Dante makes sense once the console, stagebox or install infrastructure already lives on a network. If you run NEXO cabinets, the DTD controllers carry the factory processing those systems are designed around, and the same logic applies to Martin Audio boxes and the DX range, since manufacturer presets protect drivers and are the difference between loud and right. BSS and Biamp sit at the install end of the category for room combining, paging and conference DSP.

Any of these will also run generic two-way and sub crossovers for mixed-brand rigs.

System Processor FAQs

What does a system processor actually do? It is the box between console and amplifiers: crossovers, EQ, delay and limiting that turn amps and cabinets into a system. Start with input/output count, a DX4.0 runs four in to eight out; the ASC48 four to eight at 96 kHz.

Do I need one if my amps have DSP? Often not, DSP amplifiers absorb the job. Separate processors win in installs with mixed amplification and where front-end system EQ and zoning live apart from the amps.

Standard or Dante version? Networked audio changes the wiring answer, see Dante vs analogue.
