thanks a lot.
without the service manual my handycam was going to the trash.
good job, go on.

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!

Mnemonic DATEN
Description Data Enable Low Input. This port controls the 8-bit parallel data latch and shift register. A Logic 0-to-1 transition transfers the latched data to the attenuator core (updates the gain) and simultaneously inhibits serial data transfer into the register. A 1-to-0 transition inhibits the data latch (holds the previous gain state) and simultaneously enables the register for serial data load. Serial Data Input. This digital input allows for an 8-bit serial (gain) word to be loaded into the internal register with the MSB (Most Significant Bit) first. Clock Input. The clock port controls the serial attenuator data transfer rate to the 8-bit masterslave register. A Logic 0-to-1 transition latches the data bit and a 1-to-0 transfers the data bit to the slave. This requires the input serial data word to be valid at or before this clock transition. Common External Ground Reference.

Common Positive External Supply Voltage. A 0.1 F capacitor must decouple each pin. Logic �0� powers down the part. Logic �1� powers up the part. Low Power Sleep Mode. In the Sleep mode, the AD8323�s supply current is reduced to 4 mA. A Logic �0� powers down the part (High Z OUT State) and a Logic �1� powers up the part. Negative Output Signal. Positive Output Signal. Internal Bypass. This pin must be externally ac-coupled (0.1 F cap). Noninverting Input. DC-biased to approximately V CC /2. For single-ended inverting operation, use a 0.1 F decoupling capacitor and a 39.2 resistor between V and ground. IN+ Inverting Input. DC-biased to approximately V CC /2. Should be ac-coupled with a 0.1 F capacitor.
