The Korena take

MDB-1P is a passive direct box for converting an unbalanced, high-impedance audio signal to a balanced, low-impedance output with minimal noise. It provides a 1/4-inch high-impedance input and thru connection, with a -15 dB pad available at that input. The balanced XLR output includes a ground-lift control. Its straightforward connection set makes it a practical signal-format adapter for musicians and engineers who need to move an appropriate source into a balanced output path.
