HUM Audio N-Matrix Relay-Based All Discrete Insert Matrix

The HUM Audio N-Matrix is a fully analog, all-discrete relay-based insert matrix designed for mastering and mixing engineers who demand absolute transparency, flexibility, and simplicity. Built with nearly 300 gold-contact relays and a completely balanced signal path, the N-Matrix delivers lossless routing, M/S processing, stems summing, and level trimming with pristine sonic accuracy. Every function is designed to enhance creativity without ever coloring your signal.

Inspired by the insert section of HUM Audio’s acclaimed N-Trophy mastering console, the N-Matrix expands on that foundation to offer a standalone analog insert processor of unmatched quality. Each unit is hand-built in Poland with audiophile-grade components, discrete analog circuits, and an obsession for detail. The result is a mastering-grade tool that provides full control of your analog chain while maintaining total sonic purity.
