Consistent with 5 minutes of USB stream inactivity, the USB “rate” on the display will
also be cleared once this standby limit is surpassed.

Note that the screen on/off is unrelated to the 5 minute standby setting. The screen
power-off is related exclusively to the “
SCREEN TIMEOUT” option/setting.
*The USB audio stream may be activated by any audio from your operating system. This
feature has been tested under Win 10 and macOS. Behavior may vary with other operat-
ing systems. You can verify USB stream status in the “STATUS” menu.

Auto Gain Speed
Default shows a progress bar and requires about 1/3 of a knob turn to transition between gain
states. ‘Aggressive’ minimizes internal delays and eliminates the progress bar for a much faster
transition.
2nd Harmonic Steps
Default:
0
, with a range of -75 to 75. Large values in either direction will
increase
second
harmonics.
3rd Harmonic Comp
Default:
-20
, with a range of -75 to 75. Large values will
increase
3rd harmonics.
DPLL BANDWIDTH
Default:
7
, with a range of 0 to 15. This setting directly impacts jitter rejection, with the optimal
value dependent on timing stability of your PC or audio source. Most audio sources produce
stable audio when DPLL is set to 5. We have conservatively increased the default DPLL value to
7 in order to support a wider range of sources, especially modern 4k TVs. If you encounter
stuttering, try increasing DPLL Bandwidth.
SPDIF DE-EMPHASIS
The default value of
ON
automatically enables de-emphasis when an incoming S/PDIF stream
contains such a flag, and otherwise disables de-emphasis. Setting to OFF bypasses auto
de-emphasis.
