Cautions for OPAMP Exchange

 

 

Replaceable OPAMP allows a user to enjoy user’s  own sound taste by replacing OPAMP with another. You must open the case to replace OPAMP. As shown below, OPAMP should be aligned with the groove of the socket. Regular OPAMP must be used.

 

 

 

17.jpg

 

 

 

Regular OPAMPs

Dual type, DIP type, OPAMPs that can be driven by more than ±5V ( for OPA2134, LME49860, MUSES02, USES8920 etc. ) In case your OPAMP generates noise due to the problem with compatibility, you are recommended to ontrol the volume of your computer by 80%. ( for OPA2604 etc. )

 

※ Note: You must pay close attention to the direction of the OPAMP when you exchange it. Particularly, in case of a product damage or functional problem due to wrong installation of the OPAMP, we do not guarantee service free of charge during warranty period so please be cautious for installation.
