CA-70S

Paying homage to the classic American two-stage circuit originally manufactured in the 1930's through the 1950's, the CA-70S perfectly encapsulates the huge thick tone that is what many consider to be the quintessential "old tube preamp" sound. Utilizing our component level modeling technology and meticulous refinements with the team at Coil Audio, we were able to bring the sought after sound of old octal tube circuits into the modern world.

Dripping with color

The CA-70S is extremely easy to use and immediately transforms any signal with its warm sounding octal tube circuit. The Input section includes Mic and Line amp models that go from subtle dynamic saturation to blown out distortion, a phase reverse switch, and a 4 position pad network.

The perfect pair

The Low and Negative Feedback controls perfectly interact with each other to sculpt, color and change the depth of the signal. The Low switch moves the low end from front to back while the Negative Feedback control ranges from a bright, forward sound with raised harmonics to a darker tone with a smooth and dampened harmonic structure.

Built for modern workflows

Exclusive plugin only features enables modern workflows to this classic preamp. Get instant parallel processing with Dry/Wet mix controls, use the input and output filters to high-pass or low-pass before and after the signal while working beautifully on mono or stereo signals; bringing the iconic Coil Audio sound to a new age.
