Since its debut in 1996, the Weiss EQ1 has set the benchmark for digital mastering equalizers, prized for its exceptional sonic clarity and unique flexibility. This plug-in is a precise software reproduction of the original hardware, meticulously ported line-by-line to maintain the authentic sound and behavior of the legendary unit. It offers multiple equalization modes—Minimum Phase, Linear Phase, and Dynamic EQ—allowing detailed control over audio shaping with remarkable accuracy and transparency.

Developed through a close collaboration between Weiss Engineering and Softube, the EQ1 plug-in elevates the original design with enhanced functionality and modern workflow improvements. All seven parametric bands can be set to dynamic mode with adjustable Threshold, Attack, Release, and Ratio parameters, surpassing the hardware’s capabilities. The user interface adapts intuitively based on the mode selected, ensuring quick access to controls while preserving the classic look and feel of the hardware unit.

Included alongside the EQ1 is the Weiss EQ MP, a seven-band minimum phase equalizer derived from the EQ1’s acclaimed algorithm, tailored for detailed mixing tasks requiring surgical precision. Together, these plug-ins embody decades of Swiss engineering expertise, combining rich tonal character with advanced digital processing technology. The Weiss EQ1 plug-in stands as an indispensable tool for mastering engineers seeking both heritage sound quality and state-of-the-art functionality.
