The rule of the power ON / OFF:
Power On :
Source power ON ----> NFB-2 power ON ----> Amp power ON ( preamp , headphone amp and integrated amp )
Power Off:
Amp power OFF ( preamp , headphone amp and integrated amp ) ---> NFB-2 power OFF ---> Source power OFF .

Flavor button:
Select the oversampling and digital filter response of the NFB-2.32.
　

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-2.32 still output from ACSS and RCA sockets and the signal only working with ACSS technology for the most neutral sound .
If the ACSS sockets connect to an active ACSS amp, the RCA signal will mute automatic .
　

Selector button:
Select the input modes of the NFB-2.32 . Display U : USB input. Display C : Coaxial input. Display O : Optical input.
