One and Done
Samson MD1 Pro Passive Direct Box is a premium direct box that does not compromise on signal quality. Housed in a 14-gauge steel chassis, the MD1 Pro is built to withstand the abuse of the most demanding live tours. The MD1 Pro is perfect for converting unbalanced line level or instrument signals from acoustic-electric guitars, basses, synths and more.
Making Connections
The MD1 Pro is the ultimate tool for running live sound. Convert unbalanced into balanced signals from instruments, keyboards or other line level devices to avoid signal loss and to prevent hum and RF interference. A STLX Mu-Metal shielded transformer delivers an extended, flat frequency response with ultra-low distortion.
