Pre Amps / Dynamic Processors

Dual Limiter – Classic PWM Limiter


The DUAL LIMITER has a unique design that will enhance the sonic textures of your audio system for years to come. Developed in partnership with studio and live-sound engineers, the DUAL LIMITER is very musical.

The heart of the Dual Limiter is a unique PWM gain control circuit. Combined with its’ intelligent detector, the result is a Cl​ass
