0.) Preface
Thank you for using a K.M.E. product. Inside this manual you will find useful
information for having a long and safe work with your equipment. Please take
enough time reading this manual to get in touch with all technical details of your
new product. Your K.M.E. dealer and the K.M.E. technical department is glad to

1.) Adding Plug-In-Modules to the CSA 400 D
• Remove all cables, especially the power cord, from the
CSA 400 D.
• Remove the 4 screws holding the blind plate on the rear
side of the CSA 400 D. Pull out the blind plate carefully
without overstretching the multipin cable mounted to the
plate.
• remove the multipin cable from the blind plate carefully
• Take the DDM and plug in the multipin cable to the white
socket. Take care of the polarity. The connector only fits in
one direction. Do not use tools or force to connect it. The
remaining red wire is not used by the DDM. You can stuff
it back into the CSA 400 D.
• After connecting the multipin cable to the socket
carefully fit the module in the speakers extension slot and
fix it using the 4 screws removed earlier. Now you can use
your self-powered speaker together with the plug-in
extension.
