I was having a hard time finding the problem with this Mackie 1604 unit. I didn't have a schematic. Went looking on the web and found your site and the price was more then reasonable. Ordered it and within the hour had the manual and within 15 minutes had the unit fixed. Best $4.99 I ever spent. Thank you.

This is a service manual in every sense of the word ( French and German versions of the text are included, as well as English..)
There are explanations of the mechanical and electrical functions, plenty of mechanical drawings, and the needed schematics. The quality of the scanning is excellent - all the component values are clearly legible - and very usefully there are pcb component layouts, so you can find a component on the schematic, and then very quicky pinpoint its physical location on the relevant pcb.
I cannot see how I can give this manual any less than the maximum 5 stars! Great value for money, which will pay for itself immediately. Excellent all round!

In order to make the M2 start in the bootstrap loader mode (which is needed to work with Tiny M2Flash), pin 3 of connector YB must be connected to ground at the moment of resetting the digital module (connecting the power to the module makes it reset). It may also stay connected to ground during the whole programming process, if desired. Software The program is composed of two files: One �.exe� and one �.obj� file. The first one contains the MS Windows code that runs in the PC. The second one contains the machine code that runs in the M2 microcontroller. The �.obj� file must be moved/copied to �C:\� (there is where the program looks for it.) The program writes into the flash memory the information
