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!

Scanner Card HO112
Speci�cations
Channels: 8 (4-wire) Switching: bistable, �oating relais Thermal voltage: typ. 500 nV, max. 1μV*) Max. voltage between 2 contacts: 125 Vpk Max. measuring voltage: 125 Vpk - also V/Ω-input Volt-Hertz-Product: � 1 x 106 V · Hz Max. switching current: Max.contact resistance: Life time: Insulating resistance: Capacity: Switching delay: Measurement delay: 1 Aeff approx. 1 Ω (each wire) 2 x 108 switches (0.1 A; 10 V ) 3 GΩ **) >100 pF, between contacts 20 ms between 50 ms and 300 ms
DC
*) max. 1μV after a warm-up of 1.5 h **) at rel. humidity < 60 %
Miscellaneous: With built-in Scanner Card HO112 voltage measurements are only possible up to 100 V. That means that the 600 V range of the voltage measurement functions is automatically inactive. Pin 1 is the ground connection. Channel BP is used to supply the other channels with current, e.g. for suppling sensors, LEDs etc.
