To the DAC NFB-11 variable output position or fixed output (volume)
By default, the NFB-11 is configured as a variable volume (adjustable volume). The apparatus is nevertheless designed to pass mode fixed volume. To do this, simply change the position of selection jumper. The user can thus variable output between a helmet and DAC (DAC + preamp) and a fixed output.
Warning do not position the NFB-11 in a fixed position when you connect it to a power amplifier with no volume control.
The headphone output is still affected by the volume control.
Setting up filters
Particularly useful for use with headphones to the sound very clear, two other jumper used to make the sound warmer. If both are turned on, the NFB-11 will sound less bright and less aggressive in blast treble.
digital filters
Specific filters DSD / PCM are accessible in the same way. Simply connect jumpers in the correct sequence to activate the filter you like.
Here is the mapping configuration based on the desired filters;
| PCM: FIR0, FIR1, FIR2 | |
|---|---|
| Fast roll-off, Linear: | Push Into Push Into Push Into |
| Slow roll-off, Linear: | Push Into Into Push Pull Off |
| Fast roll-off, Minimum: | Push Into Push Pull Off Into |
| Slow roll-off, Minimum: | Push Pull Off Into Pull Off |
| Fast roll-off, Hybrid: | Pull Off Off Into Push Pull |
| Brickwall filter: | Pull Off Pull Off Pull Off |
