Novation Supernova II Keyboard and Rack Repair Service


Do you own a Novation Supernova II and have these audio issues with the
Headphones / Output 1 / Output 2 jacks..?






The fault is most likely the DAC IC that generates the audio for these outputs.
This is a service where you send the motherboard PCB and I will replace the DAC.
I use the later CZ4392KZZ DAC for replacement as it has better Signal to Noise ratio.













If your Supernova II has a fault other than the DAC fault I may be able to help.
Encoders and Potentiometers:
A common fault with the Supernova is that the encoders and potentiometers wear out. The encoders are used for the two Data Selection knobs and the Tuning knob. The potentiometers are used for all the other knobs. When these malfunction the data values on the screen will jump / lag / or be difficult to adjust. Please get in touch if you need these replaced.
DSP Faults:
With a DSP fault the Effects Special LED (keyboard) or Comb Filter LED (Rack) will flash and several of the Part LEDs may be lit. When the Supernova II boots the display will be blank and the unit will not generate any sounds. If this problem appears when the unit is playing sounds then the sound will hang and the Effects Special LED (keyboard) or Comb Filter LED (Rack) will flash.
Please get in touch if you have this issue.
FLASH Write Error Faults:
With this fault the Supernova II will display "Flash Write Error !! Switch off & re-try"
It may display this instead "ROM to O/S Flash Progress [0%]"
Please get in touch if you have this issue.
Supernova II hangs when Booting:
With this fault the Supernova II will either constantly light or flash ALL the LEDs on the panel and the display will be blank. Please get in touch if you have this issue.
Supernova II OS upgrade to version 2.0:
I can upgrade your Supernova II PCB's EPROM to Version OS2.0 whilst it is in for repair.


Repair of Damaged PCB:
If a previous repair has been attempted on your PCB let me know BEFORE sending the PCB.
Any PCB arriving with track or pad damage will be rejected and returned. A handling charge may also be applied. If your PCB needs repair to the DAC area please get in touch BEFORE you buy this service.
Customer Supplied DAC:
The DAC used for this repair comes from a recognised vendor who supplies currently manufactured stock. Using this DAC I can be confident that the repair of your unit will be permanent. DACs supplied by customers WILL BE REJECTED as I cannot guarantee the authenticity of the DAC.
