Samson MD2 Pro Stereo Passive Direct Box

Plug 2 acoustic or bass guitars into the XLR inputs of a mixer or audio snake with the MD2 Pro, also great for stereo keyboards or electronic drum sets.

Samson's MD2 Pro Stereo Passive Direct Box combines two premium direct boxes in a single case. Rugged, roadworthy construction and two shielded transformers provide high-quality signal connection solutions for a variety of live sound and recording applications. The MD2 Pro is perfect for converting unbalanced stereo line level or instrument signals from keyboards, electronic drum kits, acoustic-electric guitars and more.

Custom STLX Transformers

The MD2 Pro features two of Samson's STLX Mu-Metal shielded transformers that deliver an extended, flat frequency response with ultra-low distortion and superior protection against hum and RF interference. The MD2 Pro's balanced outputs provide clean signals that are less susceptible to noise than unbalanced lines, allowing for longer cable runs. The MD2 Pro also includes a 3-position 0dB/-10dB/-20dB attenuation switch for each input to toggle between line and speaker level signals, as well as a Stereo/Mono sum switch.

Thru Jack

The MD2 Pro's Thru jacks enable you to tap off the signals from the inputs and pass the signals to amplifiers or monitors without affecting the original audio. This can eliminate the need for miking guitar amplifiers, which depending on your application may be preferable, especially as more musicians are using in-ear monitors.

Roadworthy Construction

Housed in a 14-gauge steel chassis, the MD2 Pro is built to withstand the abuse of the most demanding live tours. Its rigid outer shell protects all the MD2 Pro's internal connections, read more switches and solder joints from failure, ensuring quiet, reliable performance.
