Operation Manual

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 MCD2 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 com-
puters, CD/MP3 players, keyboards, and DJ equipment.
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 MCD2 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 input jacks are wired in parallel which enables you to tap off the signal
from the input and pass the signal to an amplifier or monitor without affecting
the original sound. 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 MCD2 Pro 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.
