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!

SERVICING PRECAUTIONS
CAUTION! ! Before servicing receivers covered by this service manual, read and follow the SAFETY PRECAUTIONS on page 2 of this publication. General Servicing Precautions 1.Always unplug the receiver AC power cord from AC power source before; a. Removing or reinstalling any component, circuit board module or any other receiver assembly. b. Disconnecting or reconnecting any receiver electrical plug or other electrical connection. c. Connecting a test substitute in parallel with an electrolytic capacitor in the receiver. CAUTION! ! A wrong part substitution or incorrect polarity installation of electrolytic capacitors may result in an explosion harzard. 2.Do not spray chemicals on or near this receiver or any of its assemblies. 3.Do not defect any plug/socket voltage interlocks with which receivers covered by this service manual might be equipped. 4.Always connect the test receiver ground lead to the receiver chassis ground before connecting the test receiver positive lead. Always remove the test receiver ground lead last. 5.Do not connect the test fixture ground strap to power supply heatsink in this receiver Electrost atically Sensitive(ES) Devices Some semiconductor(solid state) devices can be damaged easily by static electricity. Such components commonly are called Electrostatically Sensitive(ES) Device.Examples Circuit Board Foil Repair Excessive heat applied to the copper foil of any printed circuit board will weaken the adhesive that bonds the foil to the circuit board causing the foil th separate from or �lift-off� the board. The following guidelines and procedures should be flollowed whenever this condition is encountered. At IC Connections To repair a defective copper pattern at IC connections use the following procedure to install a jumper wire on the copper pattern side of the circuit board.(Use this technique only on IC connections.) 1.Carefully remove the damaged copper pattern with a sharp knife.(Remove only as much copper as absolutely necessary.) 2.Carefully scratch away the solder resist and acrylic coating(if used) from the end of the remaining coopper pattern. 3.Bend a small �U� in one end of a small guage jumper wire and carefully crimp it around the IC pin. 4.Route the jumper wire along the path of the out-away copper pattern and let it overlap the previously scraped end of the good copper pattern. Solder the overlapped area and clip off any excess jumper wire.
