The NMP 8 is a compact 8x8 DSP matrix processor and part of the TICA® Series. It is designed to route, mix and optimise audio across installed, multi-zone AV systems. It has 4 balanced mic/line inputs featuring switchable 48 V phantom power per input, as well as 4 balanced line outputs. This allows it to connect local microphones, media sources, amplifiers and powered speakers in a clean, streamlined setup.

For networked installations, NMP 8 adds 4×4 AES67 network audio channels (Dante-compatible via AES67), enabling open AoIP integration and scalability across multiple rooms and system endpoints.

NMP 8 is perfect for meeting and training spaces, hybrid classrooms, multi-zone hospitality (lobby/restaurant/terrace), and retail or public facilities combining background music with announcements. Audio can be shaped with per-channel DSP tools including EQ, delay, dynamics, and FIR filtering. Integrated functions such as automatic echo cancellation (AEC), gain sharing, gating automixers, feedback suppression and priority ducking can be added to support clear speech and automated mixing.

NMP 8 is fully integrated in QUESTRA® and designed to scale with other QUESTRA-enabled devices. Installation is straightforward: PoE powered (IEEE 802.3af) with optional DC backup, fanless for noise-sensitive environments, 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 platform for multi-zone audio, network audio interoperability, and powerful DSP processing.
