Hierarchical Dynamics Control Meets Sepia Precision
Boasting four stages of hierarchical control, the Langstrath EC24 Sepia Module brings comprehensive dynamics processing to Karno’s groundbreaking Sepia ecosystem. Unlike digital emulations, this Sepia Module uses real-world components to give you hardware-style expansion, compression, selectable vintage-style compression, and limiting. That said, thanks to advanced digital control, dialing in the perfect settings is as easy as using a desktop, tablet, smartphone, or plug-in application. Furthermore, Sepia integrates seamlessly with your setup, allowing you to route any signal at any stage, just like standard analog outboard gear, console inserts, or software plug-ins. And with instant recall, your settings are always right where you left them. Melding painstakingly re-created analog circuitry with exacting digital control, the Langstrath EC24 Sepia Module enables you to achieve everything from surgical problem-solving dynamics processing to extreme crushed creative effects, all from a single, convenient module.
Note: This product is a Sepia Module and requires a Karno L6 Rack to operate. Moreover, it is not compatible with 500 Series equipment. Please call your Sweetwater Sales Engineer if you have questions.

Delivers authentic analog sound
Karno’s Sepia is a modular system that allows studios to significantly expand their processing capabilities without the need for multiple hardware units. The system comprises a vast selection of Sepia processing Modules, many of which are from industry-leading manufacturers, along with a host chassis that also houses your I/O. What sets Sepia apart is its analog-based ecosystem. Instead of relying on digital emulations, Sepia Modules use the same tubes, transformers, opto elements, and FET circuits as their full-size counterparts.
Analog sound with digital convenience
While Karno’s Sepia ecosystem delivers authentic analog sound, it’s 100% digitally controlled. It supports most major control protocols, including HUI, EUCON, MIDI, and OSC, allowing you to take command using a wide range of devices. Sepia works seamlessly with desktop, tablet, smartphone, and plug-in applications, and it integrates effortlessly with a variety of consoles and hardware controllers. Here at Sweetwater, we’re thrilled by how you can adjust Sepia’s settings like a plug-in in a DAW while also benefiting from software-driven automation, recallability, and routing flexibility.
