SAMSON
MCD2 PRO
Stereo Passive PC Direct Box
Overview
To The Max.
- Samson's MCD2 Pro Stereo Passive PC Direct Box is the ideal solution for connecting unbalanced line level signals from laptops, CD/MP3 players, and DJ mixers to professional, balanced equipment. Durable, roadworthy construction and two Mu-metal shielded transformers provide high-quality signal connection solutions for a variety of live sound and recording applications.
Custom STLX Transformers
- The MCD2 Pro features two of Samson's STLX Mu-Metal shielded transformers that deliver an extended, flat frequency response with ultra-low distortion and superior protection against hum and RF interference. The MCD2 Pro's balanced outputs provide clean signals that are less susceptible to noise than unbalanced lines, allowing for longer cable runs.
Input Options
- The MCD2 Pro features dual 1/4", RCA and a stereo 1/8" input to accommodate any line level instrument or consumer audio connection. Its selectable Stereo/Mono sum switch allows users to accommodate typical mono "house" PA systems. Additionally, a 2-position 0dB/-12dB attenuation switch provides users with ample headroom to handle hotter inputs.
Roadworthy Construction
- Housed in a 14-guage noise-reducing steel chassis, the MCD2 Pro is built to withstand the abuse of the most demanding live tours. Its rigid outer shell protects all the MCD2 Pro's internal connections, switches and solder joints from failure, ensuring quiet, reliable performance.

SET-UP
- The MCD2 Pro can be quite useful on stage or in the studio for connecting unbalanced audio sources or instruments with pickups. By utilizing the MCD2 Pro, the signal can be sent cleanly for long distances while benefiting from the low noise and common mode rejection provided by the balanced low-level output. The diagram following shows a typical hook-up for a DJ Controller/Interface connected to a PA system.
- Set the volume controls of your audio system to the off position.
- Connect the stereo outputs of your DJ Controller/Interface or other audio source to the Left and Right Input jacks of the MCD2 Pro.
- Connect the Left and Right BALANCED OUTPUT jacks to a pair of microphone inputs of a mixer or other audio device.
- Pan the input channels of the mixer left and right.
- Raise the level of the audio system to the appropriate level.
- If you hear a hum or buzz set the GROUND LIFT switch to the LIFT position.
- If you hear distortion, set the pad switch to the -12dB position. You may need to adjust the input level of the mixer to make up for the attenuated signal.
Connecting Laptop
- Set the volume controls of your audio system to the off position.
- Connect the 1/8” stereo output of your laptop or other audio source to the STEREO Input jack of the MCD2 Pro.
- Connect the 1/4” parallel jacks to active monitor speakers.
- Connect the Left and Right BALANCED OUTPUT jacks to a pair of microphone inputs of a mixer or other audio device.
- Pan the input channels of the mixer left and right.
- Raise the level of the audio system to the appropriate level.
- If you hear a hum or buzz set the GROUND LIFT switch to the LIFT position.
- If you hear distortion, set the pad switch to the -12dB position. You may need to adjust the input level of the mixer to make up for the attenuated signal.
