This service manual is a good copy of the original, complete and fully readable. It is really useful to repair my Tv set following its clear instructions.

Excellent quality. Easy process to download. No issues or problems at all - was exactly what I was looking for and needed. Great service.

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 (LSI1: MSM6755B-10)
Containing a sound data ROM and a DAC (Digital to Analog Convertor), the CPU provides sound waveform in accordance with the pressed key and the selected tone. The CPU also records the voice picked up the microphone, using the built-in ADC (Analog to Digital Convertor) and the RAM. The following table shows the pin functions of LSI1.
