Transforming the Future of Modular Audio – Lundahl Transformers in the SEPIA Platform
The world of professional audio hardware is constantly evolving. Traditional formats like the 500-series “lunchbox” have been studio staples for decades. However, a new modular system is now pushing the industry forward: the SEPIA platform by Karno. It is designed for both studio and live use. Moreover, SEPIA combines a full analog signal path with advanced digital control in a compact and rugged format.
At Lundahl Transformers, we are proud to contribute to this innovation. We supply high-performance transformers for modules such as Langstrath Audio’s MB12, built specifically for the SEPIA format. As a result, the line between analog warmth and modern workflow is changing. Transformers play a central part in that shift.
Lundahl Inside: Trusted Sound, Trusted Design
Langstrath Audio’s MB12 SEPIA module is a prime example of this philosophy. It features:
“High-quality Lundahl transformers for both the input and the output…”
This design choice isn’t just about prestige — it’s about preserving signal integrity and sonic character in a compact format. By choosing our transformers, Langstrath ensures that the MB12 delivers the same uncompromising analog tone found in full-sized outboard gear.
Our transformers offer ultra-linear frequency response, low distortion, and excellent phase accuracy. Furthermore, these qualities matter even more in modular systems like SEPIA, where purity and size must work together. With transformer-balanced input and output stages, the MB12 maintains isolation, headroom, and transparency. Consequently, these features become essential for today’s recording and mixing environments.
Innovation Without Compromise
What makes the SEPIA platform truly unique is that it doesn’t force engineers to choose between analog and digital — it gives them the best of both worlds. Unlike the 500-series format, which offers no standard for control or recall, SEPIA introduces:
- Full digital control over analog modules
- Total recall and automation from DAWs or consoles
- Advanced routing via networked host systems
- Compact modules with premium analog circuitry
- Rugged design for both studio and stage use
Despite its modern infrastructure, SEPIA does not compromise on sound quality. In fact, the use of full-sized, high-performance analog components — including our transformers — ensures that modules retain the character and depth professionals expect.
A Platform Built for the Future
By contributing to SEPIA-compatible modules, we support a vision that merges analog excellence with digital precision. Whether used in mastering, live sound, or broadcast, SEPIA modules with Lundahl transformers deliver uncompromised audio. The format meets the demands of today’s workflows.
We are proud to collaborate with forward-thinking manufacturers like Langstrath Audio. Their commitment to sound quality matches our own. As the audio industry evolves, we remain dedicated to creating the components that shape its future.
