Franklin Audio / DI-80

The Franklin Audio/DI-80 is a power-free passive DI box with 8 channels in a 1U size. Its design prioritizes front inputs over rear inputs, allowing you to switch instruments without disconnecting existing equipment cables. It's recommended for those who want to neatly connect multiple synthesizers or sound modules.

■ A flexible 8-channel passive DI.

Keep your studio essentials neatly organized and connected to the rear panel. When a borrowed synth arrives, a friend brings in a bass, or you want to use that drum machine that's been gathering dust on the shelf, simply plug it into the front panel. Each front panel input automatically overrides the rear panel connections, allowing you to easily add new equipment while keeping your usual gear connected.

The Franklin DI-80 is an extremely clean, high-headroom 8-channel passive DI housed in a robust EIA 1U chassis with minimal footprint.

All cables fit perfectly where they belong.

This is the rack DI we've always wanted.

■ Designed to be ""unobtrusive""

The DI-80 is designed with the philosophy that ""great equipment should be so unobtrusive that the user doesn't even notice it."" With its simple and clear operation, anyone can use it intuitively, and it boasts high sound quality and robust construction.

Your frequently used equipment is permanently connected to the rear panel. When you want to play bass, or try out an acoustic guitar with a pickup, synth, drum machine, or other instruments and equipment, simply jack it in to the front panel. It functions naturally when needed, without interrupting your production flow.

The DI-80 is a DI designed not to ""make"" the user ""operate,"" but to ""focus"" on music production.

■Compact & Highly Durable Design that Blends into the Studio

Despite being an 8-channel unit, the DI-80 achieves a 1U size that fits into a standard 19-inch rack.

It can be smartly installed even in limited spaces, maintaining a clean and organized environment with neatly arranged cables.

The enclosure uses a 1.5mm thick folded steel chassis, providing high durability to withstand demanding studio use.

It's not designed to stand out, but to be used naturally and continuously for a long time.

The DI-80 functions quietly as an integral part of your production environment.

■ High-Quality Sound Through Pure Analog Design

The DI-80 is constructed with 100% analog circuitry, completely free of digital components.

Its high-headroom, high-end passive DI design faithfully transmits the nuances of various instruments, including synthesizers, basses, and drum machines. It avoids unwanted coloration while ensuring high reliability, long lifespan, and future maintainability.

Not to alter the sound, but to ""deliver it correctly.""

The DI-80 is designed as the foundation to support your daily production.
