Premium Mono Passive Direct Box for Clean Signal Transfer
The Samson MD1 Pro Mono Passive Direct Box is a professional-grade solution for musicians and audio engineers who need to send high-quality, balanced signals over long distances without interference. Whether you're connecting a guitar, bass, keyboard, or other line-level instruments, the MD1 Pro ensures clean, noise-free signal transmission while maintaining your instrument’s true tone. Built with durable, impact-resistant construction, this direct box is designed to handle the rigors of live performances and studio sessions.

Superior Sound Quality with Mu-Metal Shielded Transformer
At the heart of the MD1 Pro is Samson’s STLX transformer, featuring Mu-Metal shielding to eliminate electromagnetic interference and RF noise. This premium transformer provides an extended, flat frequency response, ultra-low distortion, and superior sound clarity. It captures the natural warmth and dynamics of your instrument, ensuring your sound is clean and true to the source, even when using long cable runs.

Flexible Attenuation for Line and Speaker Level Signals
With a 3-position attenuation switch offering 0dB, -15dB, and -30dB settings, the MD1 Pro can accommodate both line-level and speaker-level signals. This makes it a versatile tool for a variety of setups, whether you need to connect a high-output keyboard or take a signal directly from a speaker output. The attenuation feature prevents signal overload, ensuring optimal performance in any environment.

Thru Jack for Direct Monitoring
The MD1 Pro includes a 1/4" Thru jack, allowing you to send your instrument’s signal to an amplifier or monitor while simultaneously sending a balanced signal to a mixer or PA system. This eliminates the need for additional microphones on amps, making it ideal for live performances, recording, and in-ear monitoring setups.

Ground Lift Switch for Hum-Free Operation
Ground loops can introduce unwanted hum and noise into your audio signal, particularly in live and studio environments. The MD1 Pro’s built-in Ground Lift switch effectively eliminates these issues, ensuring a clean and interference-free sound. This is essential for musicians and engineers working in various venues with complex electrical setups.

Rugged Construction for Road and Studio Use
Housed in a heavy-duty 14-gauge steel chassis, the MD1 Pro is built for reliability. Its solid construction protects the internal components from damage, ensuring long-term durability even in the most demanding touring conditions. Whether you’re on stage or in the studio, the MD1 Pro is a reliable addition to any professional audio setup.
