Monoprice Stage Right by Sound Block Passive Direct Box with Gro

Throw the Sound Block in a bag, trunk, or anywhere cable and misc. audio supplies are stored. The heavy‑duty construction and passive electronics make the Sound Block nearly indestructible. This Direct Interface is extremely versatile as a Lo to Hi‑Z transformer for electric instruments and devices to XLR mic inputs or as Lo‑Hi‑Z to use a microphone with a guitar amp (not recommended only because guitar amps make terrible PAs).
High level outputs from active instruments and even speaker outputs are not a problem when using the ‑20 or ‑40 db attenuator switch. 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. A ground lift is provided for use in older buildings with janky wiring or if circuits are different from stage to where the sound system is located.
