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!

CPU (LSI2: MSM6755B-17)
The CPU reads sound data from the ROM in accordance with the pressed key and the selected tone; the CPU can read rhythm data simultaneously when a rhythm pattern is selected. Then it provides the left and the right channels� waveforms separately, by converting the data into the waveforms with two built-in DACs. The CPU also controls key and button input. The following table shows the pin functions of LSI2.
