Without inducing noise, the Samson MD1 Pro Mono Passive Direct Box allows balanced lines to be sent from your instrument long distances to your mixer.

Custom STLX Transformer
The MD1 Pro features Samson's STLX Mu-Metal shielded transformer that delivers an extended, flat frequency response with ultra-low distortion and superior protection against hum and RF interference. The MD1 Pro's balanced output provides a clean signal that is less susceptible to noise than an unbalanced line, allowing for longer cable runs. The MD1 Pro also includes a 3-position 0dB/-15dB/-30dB attenuation switch to toggle between line and speaker level signals.
Thur Jack
The MD1 Pro's Thru jack enables you to tap off the signal from the input and pass the signal to an amplifier or monitor 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 MD1 Pro is built to withstand the abuse of the most demanding live tours. Its rigid outer shell protects all the MD1 Pro's internal connections, switches and solder joints from failure, ensuring quiet, reliable performance.
Warranty: 2 Years on Audio and Wireless (1 Year on AH8 Transmitter); 90 Days on Rechargeable Batteries; 3 Years on Power Amplifiers
