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
0
LED test
Turns on all LEDs. If no light; check soldering at the LED and at the flat cables between the front boards.
1
Test 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.
2
Analog 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
3
AES 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 "+".
4
S/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 "+".
5
OPTO I/O test
A digital signal is generated on the OPTO output. When connected directly to the OPTO input the display should read "+".
6
Midi 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.
7
EXT. 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 "+".
8
Battery 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"
9
System 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 "+"
