Introduction

The purpose of this manual is to support skilled technicians in repairing the

Finalizer Express.

The manual begins with a Quick Trouble Shooting table. Here, hints, advices and

possible problems are described.

If the problem is more serious, the next step is to use the Built-in Test Program.

With this program the problem can often be narrowed down to a specific section,

channel or even component.

The next section consist of disassembly and exchange procedures. Please be aware

of warranty rights before disassembling. Refer to the warranty card.

The Block diagram gives a quick overview of the signal flow.

Circuit description is a brief description of the circuits on the different boards.

LED error codes and Jumper settings are described on page 12.

Appendix contains Schematics, Part lists and Component Layouts.

The schematics start with a main sheet, where sub sheets are shown as blocks.

Even sub sheets might have sub sheets. Inthe schematics some connections have

label names to help the reader. If a label name is framed, it means that it is

"connected" to another sheet. Label names followed by the symbol "*" mean that

the signal is active low, i.e. RESET*: the reset function takes place when the signal

is low.

Part lists contain a column called TCcode/ Item no. Use this code/no. when

ordering spare parts. If the field is empty; it means the component cannot be

ordered separately.

The coordinates in the column Pos. refer to the PCB layout page. The column

named Page refers to page no. in the schematics. In column comments a short

explanation of the function is stated. For some components, alternative types are

mentioned.

Some PCB layouts are made as gatefolds (fold-out page).

Finally appendix contains a list for mechanical parts.

This service manual does not contain schematics for the power supply module,

because any attempt to repair the power supply module must be completed with

some safety tests such as high voltage and EMC tests. Hence, it is strongly

recommended that the entire power supply module is replaced in case of

malfunction.

Quick Trouble Shooting

Use this table to solve problems or find out what to do next.

Symptom Comments / Action:

Analog in/out fails Try with other cables or read section "Built-in Test program". Note: When analog in/out is connected to unbalanced equipment, XLR

pin 3 must be connected to pin 1.

Note: If IC35 or IC36 or IC41 are defective, they should be replaced with type MC33079

Note: When running this test the input Meter must show -12dB for the channel on test.

Cannot turn power off with power switch at front The switch must be pressed for at least 1 second to turn off power. The delay provide unintended power off during recording.

Cannot run application software. Enter the Software BOOT menu, by pressing the SYNC FROM button at power on.

Select the option "V" by use of the up and down arrow keys to check the application software. Press the FINALIZE SOFTCLIP key to

execute. If corrupted; load the application software again.

Or try to run the self test prom, see section "Built-in Test program".

Bad LED's, keys or Pots. See section "Built-in Test program".

Digital or Midi in/out fails Try with other cables or read section"Built-in Test program". Digitech pedals are incompatible.

External Control In fails Try with other cables or read section "Built-in Test program".

Software Boot Menu

To access the Software Boot Menu; press the SYNC FROM button while powering on. An option letter will appear in the FINALIZE LED matrix. Use the Up and Down arrow buttons to

select between the options. To leave the Software Boot Menu; turn off the power.

Option Description

LLoad Application or Boot software directly from PCMCIA card.

RMaster Reset. Run this command and all settings are reset! Press the FINALIZE SOFTCLIP button twice to execute.

ADisplay BOOT version. Press the FINALIZE SOFTCLIP button to execute.

VDisplay the Application software version. Press the FINALIZE SOFTCLIP button to execute.

nDisplay the serial Number. Press the FINALIZE SOFTCLIP button to execute.

SStarts the loaded software. Press the FINALIZE SOFTCLIP button to execute.

Built-in Test Program

The Finalizer Express has a Built-in Test Program. To run the program; Press the BYPASS button while powering on. Each test has a number which is displayed in the FINALIZE LED

matrix. Use the left and right arrow buttons to select between the tests. Use the FINALIZE SOFTCLIP button to execute/leave a test.

To leave the Built-in Test Program; turn off the power.

Finalizer Express Built-in-Test Program has following tests:

No. TEST Function / Comments

0LED test Turns on all LEDs. If no light; check soldering at the LED and at the flat cables between the front boards.

1Test of pots This test is used for calibration of the pots. All pots must be set in middle position. If any of the pots are outside the specified range, a minus "-" will be

shown and the LED above the faulty pot will flash. A Plus "+" confirms that all controls are within the specified range. If new pots are mounted the new

values can be stored by pressing the SELECT INPUT button. "+" confirms the new values were stored succesfully.

2Analog I/O test A sine wave is generated on both analog outputs. When connected directly to one of the analog inputs the LED matrix should read "+".

Note: When running this test the input Meter must show -12dB for the channel on test.

Note: In case of defective IC35, IC36, IC41 they should be replaced with type MC33079

3AES I/O test A digital signal is generated on the AES/EBU output. When connected directly to the AES/EBU input the display should read "+".

4S/PDIF I/O test A digital signal is generated on the S/PDIF output. When connected directly to the S/PDIF input the display should read "+".

5OPTO I/O test A digital signal is generated on the OPTO output. When connected directly to the OPTO input the display should read "+".

6Midi I/O A midi signal is generated on output. When connected to the input the display reads "+" if the signal is correct. The midi signal from input is sent on to

MIDI THRU. If "-" is shown; try with another midi cable or check soldering and components in the midi circuit.

7EXT. CONTROL

IN test Tests the status on the EXTERNAL CONTROL IN. When no jack plug is inserted the display should read "-". If a jack plug is inserted and the tip of the

plug is connected to ground, the display should read "+".

8Battery test Tests the DC voltage at the Back up battery. If low; check the battery voltage is min +2.9VDC. Check also the standby current by measuring the voltage

across R27; max. 20mV (numerical value). If the voltage is higher; check IC4, IC8, C35. If necessary; refer to section "exchange of battery"

9System test Tests the MPU, DSP, DARC and SOUND RAM to some extent.

10 Ext. FADER

calibration Connect the TC MASTER FADER (or similar) to EXTERNAL CONTROL IN.

Move the Fader to position MAXimum when the "arrow up" is shown. Then press the FINALIZE SOFTCLIP button.

Move the Fader to position MINimum when the "arrow down" is shown. Then press the FINALIZE SOFTCLIP button to finish the calibration.

If the calibration went Ok the display should read "+"
