1 and 2 outputs while also recording (or monitoring) the stereo composite from the M-S LEFT and
RIGHT outputs.
Note: For more information on M-S recording we would highly recommend the AES pa-
per written by Wes Dooley and Don Streicher called “M-S Stereo: A Powerful Technique for Working in Ste-
reo”. This paper (No. 1792) is available from the Audio Engineering Society web page (www.aes.org).

Operating The A/D Converter Module
If you have purchased the optional A/D converter module for your m201, the following section will
help you become familiar with its features and its operation. The m201 A/D card is available installed
on new m201’s from the factory, or as an upgrade to your existing m201. If you need more informa-
tion about upgrading your m201 with the A/D module, please feel free to call us at 303.443.7454.
INPUT SOURCE SELECT The m201 A/D can receive signals from 3 dierent inputs: channels 1&2
from the mic preamplier section, the M-S matrix outputs, or the external balanced line inputs (locat-
ed on the back panel of the A/D module). The A/D source select switch (lower left) is used to toggle
between the three input source options, which are illuminated green directly above in the bezel.
