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).
