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.

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 "+"

Circuit Description
The Finalizer Express consist of a front, a digital, an analog and a power supply section. Here is a brief description of the sections:
Front section consist of two boards placed in the front profile. The main front board
has two matrix circuits; one for LED's and one for keys. The 7 pots are scanned by
IC8. The EEPROM contains the serial no.
The LED front board is fitted with the LED's and key switches.
Digital section is placed mainly in the middle and in the left side of the main board.
The digital section contains the Reset, MPU, SRAM, DSP, DARC, Sound RAM, FLASH,
Interfaces and PLL circuit.
Reset controls the MPU and the DA.
The Software for MPU is loaded into the FLASH. The MPU controls DSP, SRAM, Jeida,
Front, MIDI, External Control In and analog gain settings.
The major task for the DSP is to "calculate" sound. It also generates the 80MHz clock for
the DARC chip.
The DARC chip controls the sound data to/from; DSP, Sound RAM, digital in/outputsand
AD/DA converters.
Interface for MIDI and External Control In consist almost of discrete components.
The interface for the front has an integrator, which converts a 3.3kHz square wave to a
negative DC voltage for the display contrast. By changing the duty cycle of the square
wave the DC voltage and thereby contrast will also change. An attenuator allows the MPU
to measure the contrast voltage.
The PLL circuit (placed on a separate board) makes a very stable frequency at 256 x sample
rate, this frequency is divided down to 64 x sample rate and to 1 x sample rate by the DARC.
The PLL has its own power regulation.
Analog section is placed mainly on the right side of the main board.
The analog input is balanced, thus pin 3 should be connected to pin 1 when used with
unbalanced equipment.
Analog Input levels and Analog Output levels are controlled by digital potentiometers. These
potentiometers are located in a single chip, IC33.
The A/D converter is a 24bit converter . The A/D and D/A converters have also a separate
power regulation.
The D/A converter is also 24bit. A DC voltage is applied to the left & right signal output at
the converter.
After the D/A comes a 2nd order filter, then the output level and then a 1st order filter.
An electronic balanced circuit perform the output stage. Again, XLR pin 3 should be
connected to pin 1 when used with unbalanced equipment.
Power supply section consist of a separate Power Supply Module and some regulation
circuits on the main board.
One of the regulation circuits has an electronic switch for the +/-15V. But the electronic
switch for the +5V is mounted inside the Power Supply Module. The switches are controlled
by the Stand By circuit. The Stand By circuit is supplied from a separate power wire from the
Power Supply Module.
This service manual does not contain schematics for the Power Supply Module, because any
attempt to repair the module must be completed with some safety tests such as high voltage
and EMC test. Hence it is strongly recommended that the entire Power Supply Module is
replaced in case of malfunction.
