Thermionic Culture Robin Passive DI Box Review
The Thermionic Culture Robin Passive DI Box uses a high-quality E.A. Sowter transformer that gives your signal a strong 10:1 ratio. That means it boosts the signal in a way that keeps your sound rich and balanced. It increases the input impedance seen by your instrument by 100 times, helping your guitar or bass shine even when paired with a standard mic preamp. You can also bypass the transformer entirely, connect a second amp, or cut unwanted noise with the ground lift switch. It’s simple, effective, and built to last.
