The NMP 32 is a compact 32×32 DSP matrix processor and part of the TICA® Series. It is designed to route, mix, and optimise audio across medium to large-scale installed and networked AV systems. With 4 balanced mic/line inputs featuring switchable 48 V phantom power per input, and 4 balanced line outputs, it supports clean local connectivity for microphones, sources, amplifiers, and powered loudspeakers.
For networked installations, NMP 32 provides 28×28 AES67 network audio channels (Dante-compatible via AES67), enabling open AoIP integration and scalable distribution across multiple rooms, zones, and network endpoints.
NMP 32 is perfect for campus and corporate deployments with many rooms and audio zones, hotels and event venues with ballrooms and breakouts, multi-zone hospitality, and public facilities where audio must be routed reliably across a wider system. Audio can be shaped with per-channel DSP tools including EQ, delay and dynamics. Integrated functions such as gain sharing, gating automixers, feedback suppression and priority ducking can be added to support clear speech and automated mixing.
NMP 32 is fully integrated in LD Systems QUESTRA® and designed to scale with other QUESTRA-enabled devices. Installation is straightforward: PoE powered (IEEE 802.3af) with optional DC backup, fanless for silent operation, and built in a 1/3 19″ rack, 1U format with an optional rack tray for flexible mounting.
The perfect solution for professional installers and users who need a compact, network-centric platform for large-scale multi-zone audio, AoIP interoperability, and a scalable QUESTRA® workflow.
