NFB-1.32 (DSD / DXD )
Dedicated Discrete Fully Balanced DAC
DSD , DXD support from USB
32bit / 384K Sabre ES9018
32bit / 384K Asynchronous Transfer  USB-32 Chip

The rule of the power ON /  OFF:
Power On :
     Source power ON ---->  NFB-1.32 power ON ----> Amp power ON ( preamp , headphone amp and integrated amp )
Power Off:
    Amp power OFF ( preamp , headphone amp and integrated amp ) ---> NFB-1.32 power OFF ---> Source power OFF .

Easy setting for the SPDIF input through DIR module or feed to ES9018 direct :
　

        The NFB-1.32 have built in DIR module (Users can choice either DIR9001 and WM8805 install while place the order, in default install WM8805 and SPDIF feed to ES9018 direct ) .  
        Users  can choice the SPDIF signal feed to either ES9018 direct and through DIR module with 3 jumpers setting , which is simply for users choice different sound flavors .
        In default SPDIF feed to ES9018 direct
        The setting guide:
        1, Pull off the power cable at first .
        2, Take off the top cover of the chassis.
        3, Setting the jumpers .
        4, Get back the top cover and push into the power cable tight .

Please note :
1,      The unit is based on the ES9018 chip, the ES9018 have built in the top grade PLL can avoid jitter, but this PLL have high request from the source , if connect with low grade source ( like the low grade PC sound card ) coaxial or optical may cause the sound drop off (distortion) . This is not the defect, the most electric engineers known the exact PLL have high request from the source clock.
       The USB have very low jitter so no problems .
       In our experiences, we only got less than 10 users feedback have encounter this matter and they most are report with these products:
       On board PC sound card or value USD10 PC sound card , Apple New Airport Express with optical connect , USD01 while over 96KHz output .
       In this case, user can setting the unit SPDIF input through the DIR module then feed to the ES9018, can have jitter tolerance ability increase to 7X times.

Setting button:
Select the NFB-1.32 output level at high (2.5V RCA, 5V XLR) or low (1.25V RCA , 2.5V XLR) , ACSS output have not function.
