The rule of the power ON /  OFF:
Power On :
     Source
power ON ---->  NFB-3  power ON ----> Amp power ON ( preamp , headphone amp and integrated amp )
Power Off:
    Amp power OFF ( preamp , headphone amp and integrated amp ) --->
NFB-3  power OFF ---> Source power OFF .

Flavor button:
Select the oversampling and digital filter response of the NFB-3.33.
 

ACSS/RCA button:
Choose between RCA and ACSS signal output configure, display 1 is the signal configure for ACSS output, display 2 is the signal configure for RCA output.
No matter what mode is selected , the NFB-3.33 still output from ACSS and RCA sockets and the signal only working with ACSS technology for the most neutral sound , unless the ACSS sockets connect to an active ACSS amp, then the RCA signal will mute automatic .
 
Selector button:
Select the input modes of the NFB-3.33 .   
Display U : USB input.     Display C : Coaxial input.    Display O : Optical input.
