MACKIE HR824 26 pages English-only Service Manual contains:
1) HR824 technical overview with the description of front and rear panel switches.
2) HR824 specs
3) Block Diagram
4) Wiring Diagram
5) Packaging management
6) Spare part & final assembly list (for PCB rev A and B) + exploded view
7) Test Procedures (where, how to measure voltage...) including Test Point diagram on the PCB.

Excellent guide: very clear, good scan quality enabling us to print readable diagram :-)

This Service manual is very well scanned and its clean to read, no any anti-theft words that un-english could understand. I got my CCD600 working with this manual and it´s clear shematics :)

I was very pleased with the service provided and was surprised at how good the quality was of the manual. I thought it may be a third generation copy or so, but it is as good as the websites that charge 3 times this much. I repair some electronics for family and friends without charge, so this is perfect for me. Thank you very much.
3.1.6 Manual tracking mode (Auto tracking ON/OFF) setting (1) In order to set to the manual tracking mode during tape playback, press the �SP/EP(LP)� button on the remote control unit. � Each press of the button switches the auto tracking ON or OFF. � When the auto tracking is OFF, the monitor screen displays �AT: OFF�. � When the manual tracking mode is set, the tracking is placed at the center position. (2) Press �channel +/-� to adjust the tracking manually.
3.2 Mechanism compatibility adjustment Notes: � Although compatibility adjustment is very important, it is not necessary to perform this as part of the normal servicing work. It will be required when you have replaced the A/C head, drum assembly or any part of the tape transport system. � To prevent damaging the alignment tape in the compatibility adjustment, prepare a cassette tape (for self-recording/playback), perform a test on it by transporting it and making sure that the tape is not bent by the tape transport mechanisms such as in the guide rollers.(See Fig.3-2-2a.) 3.2.1 Tension pole position Notes: � This adjustment must be performed every time the tension band is replaced.

3.1.7 EVR adjustment Some of the adjustments require the adjustment performed by the EVR system. The main unit have EEPROMs for storing the EVR adjustment data and user setups. Notes: � In the EVR adjustment mode, the value is varied with the channel buttons (+, �). The adjusted data is stored when the setting mode changes (from PB to STOP, when the tape speed is changed, etc.). Take care to identify the current mode of each adjustment item when making an adjustment. � When changing the address setting in the EVR adjustment mode, use the Jig RCU or the remote controller having numeric keypad with which a numeric code can be directly input. The remote control code of the Jig RCU corresponds

(1) Play back the back tension cassette gauge (A). (2) Check that the indicated value on the left side gauge is within the specified value (G). (3) If the indicated value is not within the specified value (G), perform the adjustment in a following procedure.(See Fig.3-2-1a.) 1) Remove the top frame, cassette holder and side frames (L/R) all together. (See �section 2 mecha-nism�.) 2) Rotate the loading motor gear to move the control plate so that the triangular stamping to the left of the �P� stamping is aligned with the stamping (a) on the main deck. This positioning is mode (B1). 3) Adjust by turning the adjustment pin so that the tip of the tension arm is aligned with the stamping (b) on the main deck. 4) Rotate the reel disk (S) by about one turn clockwise and make sure that the round hole of the adjustment pin is located in the �OK� range. If it is outside this range, restart the adjustment from the beginning. After completion of the adjustment, rotate the loading gear motor to return it to the mode (B2) position.
