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!

LED FLASHING CODE
PURPOSE: The led indicates the power mode, occurred I2C error and On timer
INPUT:
Current power mode - I2C Errors - On timer
Processing: - If in STANDBY mode and On timer inactive then switch LED off. - If in STANDBY and On timer active set LED to blinking, (switch on and off at 1 Hz with a 50% duty cycle). - If in POWER-ON mode, switch LED on. - If an I2C error occurred, let the LED blink at 1 Hz, 50 % duty cycle. For the blinking times see the Table below.
Note: Only when an I2C error occurs for a number of times, or for a number of seconds, the I 2C error is handled by the system (that is ,only then the set will go to standby, the led starts blinking).
