Introduction
A direct insertion box, or DI box, converts unbalanced high impedance signals to balanced low
impedance signals. This provides the facility to run long cables without deterioration of the signal, as
well as connecting audio signals to a mixer’s microphoneinput.
Samson’s S-Max Direct Boxes combines premium sound circuitry with durable, roadworthy
construction to provide high-quality signal connection solutions for live and studio applications. The
Samson MD1Professional Mono Passive Direct Box offers a variety of DI solutions for live sound and
recording applications. You can connect all kinds of audio signals like those from keyboards, drum
machines, mixers, guitars, and outboard signal processors.
Samson’s STL transformer delivers an extended, flat frequency response, ultra-low distortion,
and eliminates hum and RF interference. The MD1 balanced output provide a clean signal, that is
lesssusceptible to noise when compared to an unbalanced cable, which allows for running longer
lengths of cables.Another benefit from a balanced connection is CMR (Common Mode Rejection),
which provides cancellation of interference (hums and buzzes), while leaving the original signal pure.
With proper care and maintenance, your MD1 will operate trouble-free for many years. Should your
direct box ever require servicing, a Return Authorization (RA) number must be obtained before
shipping your unit to Samson. Without this number, the unit will not be accepted. Please visit
www.samsontech.com/ra for an RA number prior to shipping your unit. Please retain the original
packing materials and, if possible, return the unit in its original carton. If your MD1 was purchased
outside of the United States, contact your local distributor for warranty details and service information.
