A direct insertion box, or DI box, converts unbalanced, high impedance,
signals to balanced, low impedance signals providing the facility for
connecting audio into a mixer’s microphone input. Samson’s S-Max
Direct Boxes combines premium sound circuitry with durable, roadwor-
thy construction to provide high-quality signal connection solutions for
live and studio applications. The Samson MD2 Pro Professional 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, and outboard
signal processors.
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 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.
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 trou-
ble-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.
