Radial’s high-performance StageBug SB-2 passive DI delivers warm, vintage-inspired direct sound from your bass, keyboard, or acoustic guitar. Equipped with a custom Eclipse ET-DB3 transformer, the SB-2 properly impedance-matches and balances your signal while eliminating buzz and hum caused by ground loops. This ultra-compact direct box easily handles high input levels with smooth, natural compression, and includes a 15dB pad for extra-hot sources such as active basses or digital pianos. Although the StageBug SB-2 is a mono device, its built-in stereo-to-mono merge function lets you input a TRS stereo signal without having to change settings at the source. It’s a tiny box with huge performance — and one we’re confident you’ll love.
The StageBug SB-2 is a compact passive direct box designed for active basses, keyboards, and acoustic instruments. Its ultra-portable size makes it small enough to fit inside most instrument cases, while its smart feature set — including a stereo-to-mono merge function — helps you save valuable mixer channels. With transformer isolation for noise-free operation and true plug-and-play simplicity, the SB-2 is an ideal solution for stage and studio use.
The SB-2 begins with a 1/4" input and thru-put to feed your stage amp, routing the signal through a custom Eclipse ET-DB3 transformer that balances the output and delivers smooth, vintage-style warmth. A -15dB pad is available for high-output sources such as active basses and digital pianos, preventing overload. The innovative stereo-to-mono merge function makes it easy to use stereo keyboards or laptops without reconfiguring their output settings, reducing setup time and saving mixer channels. A transformer-isolated XLR output wired to the AES standard ensures clean signal transfer even over long cable runs, while the ground-lift switch eliminates buzz and hum caused by ground loops.
Plug in your acoustic guitar and enjoy smooth dynamics with a warm, natural character. Its portable size makes the SB-2 perfect for gigging musicians on the move.
Connect your bass to the SB-2, send the thru signal to your amp, and run the XLR output to the PA for a clean, noise-free direct tone. Transformer isolation prevents ground-loop hum for professional results.
The SB-2 excels as a keyboard DI, automatically merging stereo sources to mono and balancing the signal for cable runs up to 100 meters (300 feet) without added noise. It's a reliable, portable solution for both stage and studio environments.
