These documents are made available for qualified service engineers who have a need to repair and calibrate QSC amplifiers. The service manuals usually contain parts listings, troubleshooting and test guidelines, chassis drawings, and schematics. To save in transmission time and disk space, the files are saved in compressed form. The service manuals are PDF files compressed into password-enabled self-extracting WinZip archives; the older schematics are JPEG files in self-extracting archives, while the newer ones are PDF files. To access the JPG schematic files, download the file of choice into a temporary directory. From here, run the file that was downloaded. After this is done, the files will then become available for viewing where you may either open them using your Internet browser or other graphics software. The PDF files may be viewed in the same manner using Adobe Reader. 

    NOTE: All schematics shown here are free of charge and may be downloaded. However, for security reasons, the service manuals shown below are available through the use of a password. You will be able to download the service manuals, but upon launch, a password will be requested. 

    If you are not an authorized warranty service center and would like to purchase access to these service manuals, please call us to obtain a password at 800/772-2834 or 714/957-7150.
