 Quick Trouble Shooting: 

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

Symptom 

Comments / Action: 

Distortion 

If SAMPLE RATE is set to DI, when using analog input, distortion will appear. Set SAMPLE RATE to 44.1 or 48 or 
connect an external clock to digital input. 
If SAMPLE RATE is set to 44.1KHz and the digital input signal is 48KHz (or vice versa), distortion will appear. The 
Finalizer cannot do real sample conversion! 

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. 

Blank display. Cannot run application software. 

Enter the SOFTWARE BOOT menu, by keeping HELP button pressed at power on. 
Dial option to INFO and press OK to check the application software. If corrupted; load the application software again. 

Picture on display "frozen" 

Normally caused by electric shock. Turn power off and on. Automatic re-initialization of the display is implemented in 
software ver. 1.08 or higher, meaning that frozen condition only takes place for about 5 seconds. 

Lines or spots in display 
Backlight is blinking 

Make sure no external equipment is influencing the display, i.e. magnetic fields, hot fields. If the picture is still distorted, 
replace the display. If the backlight is bad or blinking; check the soldering on the display itself, especially the two 
connections going to the upper part of the display. 

Message: "Preset Error" 

Appears normally at first power up after RAM memory was corrupted. All Presets are set to factory default! 

Message: "RAM corrupted" 

Check BATTERY with Built-in Test program. See "Built-in Test program". 

Message: "DSP Error" 

Check SYSTEM with Built-in Test program. See "Built-in Test program". 

Bad LED's, keys or ADJUST wheel. 

See section "Built-in Test program". 

Analog in/out fails 

Try with other cables or read section "Built-in Test program". Notice: When analog in/out is connected to unbalanced 
equipment, XLR pin 3 must be connected to pin 1. 

Digital or Midi in/out fails 

Try with other cables or read section "Built-in Test program".
