Knif Audio Mastering Controller

Knif Mastering Controller is a high-end audio mastering console designed to manage the entire mastering chain with precision and ease. It offers extensive routing and processing capabilities, combining cutting-edge components with an uncompromising focus on sonic transparency and operational flexibility.

The console features Elma® rotary switches and premium push buttons manufactured in Japan, each with tasteful backlighting and a satisfying, low-volume click that reflects the unit’s refined craftsmanship.

An optional built-in AES/EBU router allows seamless selection between multiple digital sources, reducing the need for numerous DAC channels and streamlining hybrid workflows.

By default, the unit operates via an external power supply, though an optional 2U analog metering bridge with integrated power supply is also available.
