Operation Manual
A direct insertion box, or DI box, converts unbalanced, high impedance, sig-
nals to balanced, low impedance signals providing the facility for connecting
audio into a mixer’s microphoneinput.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 MD2 ProProfessional Stereo 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,
outboard signal processors and even from the powered speaker output from
an amplifier.
Featuring two of Samson’s STLX Faraday shielded transformer, which deliver
an extended, flat frequency response, ultra-low distortion, and eliminates hum
and RF interference. The MD2 Pro balanced output provide a clean signal,
that is lesssusceptible 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.
The THRU jacks enables you to tap off the signal from the input and pass the
signal to an amplifier or monitor without affecting the original sound. This
can eliminate the need for miking the guitar amplifier, which in many cases
is preferable, especially as more bands are using in-ear monitors. The Stereo/
Mono switch mixes the two input channels together for situations where the
number of audio channels is at a premium.
With proper care and maintenance, your MD2 Pro will operate trouble-free for
many years. Should your direct box ever require servicing, a Return Authori-
zation (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.
