Samson MD2 PRO Stereo Passive Direct Box

The Samson MD2 Pro Stereo Passive Direct Box solves a common live-sound and studio problem: getting clean, balanced signal from stereo instruments, media players, or laptops into a mixing console or recording interface without introducing noise, hum, or signal degradation. Inside its 14-gauge steel enclosure sit two Samson STLX Mu-Metal shielded transformers — one per channel — that convert unbalanced inputs to balanced XLR outputs while providing galvanic isolation. Mu-Metal shielding is particularly effective at blocking the low-frequency magnetic interference that plagues stages crowded with power cables and lighting dimmers, keeping your signal path quiet even in electrically hostile environments.

Each of the MD2 Pro's two channels features its own 3-position attenuation switch at 0dB, -10dB, and -20dB, allowing you to precisely match the input sensitivity to your source — from a passive bass guitar to a hot keyboard output — without clipping the mixer's preamp. A stereo/mono sum switch adds flexibility for situations where a single console channel is all that is available, and thru jacks on both channels let you pass the original signal onward to a stage amp or monitor without splitting or degrading it. Because it is entirely passive, the MD2 Pro has no batteries to die mid-set and no phantom power requirement to configure. It simply works every time you plug it in, making it a dependable tool for touring musicians, AV installers, and studio engineers who value signal integrity and zero-maintenance reliability.
