The HUM Audio N-Matrix Insert Matrix gives you total control over your mastering and mixing workflow. Split, sum, or re-order your gear with zero loss and pure sonic transparency - the N-Matrix is the ultimate analog routing powerhouse for modern studios.
The HUM Audio N-Matrix Insert Matrix is built entirely from discrete components and relay-based passive switching, the N-Matrix delivers a truly transparent signal path - allowing you to manage complex analog chains with speed and precision while keeping your sound 100% pure. Handcrafted in Poland, the N-Matrix gives you the ability to split, sum, re-order, and process your analog gear any way you want. Whether you’re routing EQs and compressors in mastering, creating parallel chains for creative mixing, or exploring M/S processing, the N-Matrix keeps you connected to the sound and workflow of high-end analog audio. This is not just another patchbay - it’s a creative hub for your entire analog setup.
HUM Audio N-Matrix Insert Matrix Features
- Fully Analog, All-Discrete Design: 100% analog signal path built from discrete components for maximum musicality and clarity.
