NMP8 and NMP32 are not intended to be “small vs. large” versions of the same processor.
They are two specialized tools within the same platform, designed to work together or
independently, depending on the project requirements.
The core idea of the NMP platform is:
Distribute DSP power and system scaling exactly where it is needed — not everywhere.
Simple way to understand NMP32
NMP32 is the system backbone. It focuses on scale, distribution, and flexibility rather than per‑channel DSP Depth.
Why are both devices priced the same?
At first glance, the identical price can be confusing. However, both products deliver comparable
value — in different dimensions.
NMP8: Value through DSP depth
* High DSP consumption per channel
* FIR and AEC are among the most DSP‑intensive features in professional audio
* Optimized for quality and processing flexibility
NMP32: Value through DSP breadth
* Much larger matrix (32×32)
* Significantly higher routing complexity
* Designed to scale systems efficiently
In simple terms:
* You pay for DSP power per channel with NMP8
* You pay for DSP scale and system size with NMP32
Both products address the same professional price segment, but serve different system tasks.
Why doesn’t NMP32 include FIR and AEC?
This is a deliberate technical design decision, not a product limitation or segmentation strategy.
Important points:
* FIR filters and AEC require very high continuous DSP resources
* A 32×32 matrix already consumes a large share of DSP capacity
* Enabling all DSP features on all channels would either:
- Reduce system stability, or
- Significantly increase cost and size
NMP8 and NMP32 are not competing products — they are complementary tools.
Together, they offer a flexible, professional solution that adapts to real‑world installation needs
instead of forcing customers into a one‑size‑fits‑all processor.
If advanced DSP is required everywhere, NMP8 is the right choice. If large systems need to scale efficiently, NMP32 is the right choice. For many typical installations — for example an 8×8 matrix — combining one NMP8 with one NMP32 allows customers to get the best of both worlds: advanced DSP processing where it matters, together with flexible routing and system scalability.
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.
