User’s Guide ADI-2 Pro FS - v 2.5
The inclusion of the SRC status helps to find simple errors that can happen due to the many
options of the ADI-2 Pro, which naturally reside in different parts of the menu structure. For
example the SRC might be active, but SPDIF signal is dead audio-wise. A quick glance at the
State Overview will reveal that the SRC was set to work on the wrong input (AES)…
15.4 Dark Volume
This screen has been added as alternative to the other
meter screens, which even with the dark theme selected
might be disturbing in some situations. Dark Volume shows
the current volume setting of both analog outputs, their
current reference level setting, the amount of Bass/Treble
gain applied, and the Balanced Phones mode. It is low in
brightness, still fully readable in bright environments, and
has zero flickering or moving elements (level meters).
Volume and Bass/Treble adjustments happen right in this
screen, which makes its functionality not only visually
pleasing.
Despite this screen having no level meters, overloads caused by Volume, PEQ or Bass/Treble
are easy to recognize. The big gain numbers are coupled to the over detection of the analog
outputs. They change their color to red when overload occurs.
As with the other meter screens, once selected it becomes the default screen, automatically
shown after power-up or when leaving a menu.
16. Warning Messages
The ADI-2 Pro will show different warning messages and provide guidance in certain cases.
Hi-Power Mode Active
When Hi-Power mode is active with the Volume set higher
than -15 dB and a phone is plugged in, this message reminds
the user to check the current volume setting, and to make
sure the used headphone will stand the high output power
without getting destroyed. The audio signal is held at a low
volume until the gain is set to -15 dB or below. The Volume
knob is active on the current phones output and can be used
to turn down the volume. Once -15 dB is reached the volume
is ramped up to the current gain.
Pressing encoder 1 removes the message immediately, with volume ramped up within 2 sec-
onds to the set value.
The message will also vanish when the phone is unplugged again.
This message is not shown when Volume is set to -15 dB or lower, or when the device is
switched on while the phones are already connected.
