Introduction
A direct insertion box, or DI box, converts unbalanced high impedance signals to balanced low imped-
ance 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 MDA1 Mono
Active Direct Box offers a variety of DI solutions for live sound and recording applications. You can con-
nect all kinds of audio signals like those from keyboards, drum machines, mixers, guitars, and outboard
signal processors.
Unlike passive direct boxes, the MDA1 is active, which means it has a power supply, so you can rely on
an even frequency response on any audio signal you connect to regardless of its output impedance. The
MDA1 is ideal for connecting instruments with passive pickups, which have very high-impedances, by
preserving the top end of the instrument's frequency response. The balanced output provides 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 MDA1 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 call Samson at 1-800-3SAMSON
(1-800-372-6766) for an RA number prior to shipping your unit. If your direct box was purchased outside
of the United States, contact your local distributor for warranty details and service information.
