Passive DI Box with Ground Lift and Attenuator

The sound block is a very easy to use passive device. Simply plug your 1/4" output from a guitar or electric piano, plug an XLR cable into your mixer's channel input, and you're done. It provides impedance and signal matching for the direct connection of instruments to mixers and amplifiers for stage and studio applications. You can rest assured that your sound source will reach the console balanced and noise-free.
