Phones Output 3/4 - RME Audio ADI-2 Pro User Manual

12.3 Phones Output 3/4

Subpage Settings has the same settings as listed for Main Output 1/2, plus:
Source
Default: Auto. The source of the output Phones Out 3/4 can
be chosen manually anytime. Available options are: Auto,
AES, SPDIF, Analog, USB 1/2, USB 3/4. Auto here not only
means current or available signal, but also channels 1/2.
Hi-Power
Off, On. Reference level for 0 dBFS is +7 dBu at the output.
With Hi-Power on reference level is 15 dB higher, +22 dBu.
13. EQ
The key EQ brings up a graphical EQ screen to set the EQ
quickly and with full overview. It is available on all analog
I/Os. The I/O - Settings submenu Parametric EQ mirrors
the settings done in this screen.
On the top level, turn encoder 1 to change between Analog
Input, Main Output 1/2 and Phones Out 3/4. Turning
encoder 2 will scroll through all 5 bands, as can be seen in
the parameter line. This function allows to see/check/verify
all parameters of all bands quickly, without the danger of
changing any of them.
Push encoder 2 to move the cursor to the parameter line,
with all values shown in white color. It is now possible to
adjust all parameters by turning the three encoders. The
Volume knob changes Gain, encoder 1 Frequency,
encoder 2 Q (Quality factor). All changes are shown in real-
time as frequency response curve (Bode plot), making it
very easy to find the desired settings.
To change to the next band push the encoder Volume.
The five bands have different colors to clearly show what is currently selected: band 1 red, band
2 yellow, band 3 green, band 4 light blue, band 5 dark blue.
Band 1 and 5 also allow to set the filter to Peak or Shelf mode, plus Low Cut/Hi Cut. This func-
tion is accessed by pushing encoder 2 so that the cursor moves down to the small filter symbol
in the lower right. It is no longer grayed out. Turning encoder 2 now toggles through the avail-
able settings, with the symbol changing according to the selected function.
The frequency graphics give a precise overview of the filter results. Overlapping filters influence
each other. This can be used to achieve more than 12 dB gain, or to generate difficult frequency
response optimizations.
Note: The ADI-2 Pro has an internal headroom of 24 dB. Extreme boosts with overlapping filters
could cause an internal overload. Such an overload will be visible as it is displayed by the level
meter below the EQ, as well as the channel's level meter. Reducing the output volume will pre-
vent any clipping as long as the headroom of 24 dB is not exceeded. In real-world operation
that is always the case, the ADI-2 Pro will not distort internally.
