Samson SAMDA1 MDA1 Active Mono Direct Box

Premium Active Direct Box for Studio and Stage
The Samson MDA1 Active Mono Direct Box is designed for musicians, producers, and sound engineers who need a reliable solution for converting high-impedance instrument signals into balanced, noise-free audio. Whether you're recording in a professional studio or performing live, this active DI box ensures a clear, full-range signal transfer while eliminating unwanted noise and interference.

Ideal for Passive Pickups and Long Cable Runs
The MDA1 is especially suited for guitars and basses with passive pickups, preserving the instrument’s natural frequency response by preventing high-end roll-off. Unlike passive direct boxes, this active DI ensures a consistent and even frequency response, no matter the output impedance of the connected source. The balanced XLR output reduces noise interference, making it ideal for long cable runs on large stages or recording setups.

Flexible Attenuation and Thru Jack for Versatile Routing
Equipped with a two-position -15dB attenuation switch, the MDA1 adapts to a variety of audio sources, from low-output instruments to hot line-level signals. The Thru jack allows the original signal to pass through to an amplifier or monitor without degradation, eliminating the need for complex setups and reducing reliance on miking guitar amps. This feature is especially useful for musicians using in-ear monitoring systems.

Rugged and Reliable for Touring and Studio Use
Built to handle the rigors of live performances and professional studio environments, the MDA1 is housed in a durable 14-gauge steel chassis. Its robust construction protects internal components from wear and tear while ensuring long-lasting performance. Whether you're on the road or working in a controlled studio space, the MDA1 delivers quiet, interference-free operation.

Multiple Power Options for Maximum Convenience
The MDA1 runs on either 48V phantom power from a mixer or a 9V battery, ensuring that it functions reliably in any setup. This flexibility allows users to integrate the DI box into any audio system without worrying about power availability, making it a convenient choice for both live sound and studio recording applications.
