Samson MD1 Pro 1-channel Passive Instrument Direct Box

The Samson MD1 Pro upgrades the standard MD1 with a Samson STLX Mu-Metal shielded transformer for superior noise rejection and a cleaner signal path. The 3-position attenuation switch (0 dB/-10 dB/-20 dB) handles everything from passive bass pickups to hot active electronics and line-level sources without distortion.

Like its sibling, it converts unbalanced instrument signals to balanced XLR output for the mixer, with a 1/4-inch thru for your amp. The ground lift switch is there for eliminating hum. The shielded transformer makes a noticeable difference in noisy stage environments where RF interference and ground loops can wreak havoc on your signal. If you've been dealing with buzz issues using basic DI boxes, stepping up to the MD1 Pro is a worthwhile investment for cleaner sound.
