The Radial SB-5 multimedia DI box has been added to the Amazon Links page. This is a very compact passive stereo DI box that features a permanently attached minijack cable and balanced outputs on both XLR and quarter-inch. It’s small enough to fit into the front pocket of a laptop bag!
The quarter-inch outputs are stereo whereas the XLR output sums the signal to mono, often the best option in live sound situations where a significant part of the audience can only hear one side of the sound system.
