The Samson MCD2 Pro is a 2-channel passive direct box designed specifically for connecting consumer audio and A/V sources to professional balanced equipment. It accepts input from 1/4-inch, RCA, and stereo 1/8-inch connections, so you can plug in laptops, phones, CD players, DJ mixers, and other line-level devices with whatever cable you have handy.

A stereo/mono sum switch accommodates mono PA systems, and the 2-position 0 dB/-12 dB attenuation switch provides headroom for hotter signals. Ground lift switches on both channels eliminate hum and buzz. The MCD2 Pro is the box you want between a DJ's laptop and the house PA, between a presenter's device and the conference room sound system, or anywhere you need to convert consumer audio to a balanced signal. Compact, reliable, and always useful to have in your audio toolkit.
