Input Settings Screen

This screen displays filtering and processing 

parameters for the chosen input (which 

appears as a heading). Active functions are 

highlighted in red. Turning the knob allows to 

navigate between the options of that func-

tion. Clicking on the knob confirms the selec-

tion and takes you to the next function. If you 

do not want to change anything you can 

simply click once again and move on to the 

next item on the menu. 

If you wish to return to the main screen, simply go to 

“Back to the Main Screen”

 and turn the 

knob.

Filter:

 

in many files there is little real musical 

content above 25-30kHz the rest being noise. 

The filters address this issue especially for high 

resolution files. Landing on the filter highlights 

it in red and opens the selection. Turning the 

knob takes you through the seven (7) preset 

filter choices. These are,
•  Fast roll-off, minimum phase. 
•  Slow roll-off minimum phase. 
•  Fast roll-off linear phase. 
•  Slow roll-off linear phase. 
•  Brick wall. 
•  Hybrid, fast roll-off minimum phase. 
•  Apodizing, fast roll-off minimum phase
Clicking on your selection confirms your 

choice and takes you to the next function. 

We recommend you start experimenting with 

these after the first 3-4 weeks of operation.

IIR 

(infinite impulse response): set at 47.44kHz 

for PCM it is user selectable for DSD (50-60-

70kHz) 

Lock speed:

 

this function sets the number 

of audio samples that are required from the 

incoming signal before the DPLL and jitter 

eliminator lock onto it. The default value is 

16384. 

 

On the rare occasion where there is no lock 

turn to the other values, preferably in de-

scending order 8192, 4092, 2048, 1024. 

De-emphasis:

 

a filter that attenuates high 

frequencies and counteracts emphasis often 

used in mastering. We recommend that you 

leave this disabled.
Keeping the knob pressed for 2-3secs takes 

you to the 

General settings screen
