Franklin Audio DI-10 Passive Direct Box

No hum, no headache, no tone shift — just a bulletproof DI that gets out of the way. The Franklin Audio DI-10 passive direct box features a custom-wound transformer for full-band frequency response and perfect isolation, high input impedance that feels natural to play through, and a low-profile enclosure that fits anywhere without demanding attention. The result is a DI that takes guitar, bass, and keys straight into mic preamps with zero noise and zero colouration—simple, reliable, and built to outlast everything else on your desk.

The DI-10 features a mono input for sources like synths, keyboards, drum machines, guitars and basses. A DI balanced XLR output sends audio to your interface or preferred mic preamp chain. Through connection provides an untouched copy of your original input signal for use in parallel processing, or sending to amps.

Connect your guitar, bass, synth or drum machine to the DI-10 input using a standard instrument cable. The high input impedance input preserves your tone and playing feel. Run a balanced XLR cable from the DI-10 output to your mic preamp or interface. The custom transformer converts your signal cleanly with zero added noise or tone shift. That's it. The DI-10 gets out of the way and lets your instrument sound like itself—just cleaner, quieter, and ready for any preamp or processing you throw at it.
