15. Top Screens

The ADI-2 DAC has four different top screens: an Analyzer showing the audio signal content of

the analog outputs, a State Overview showing the digital states of SPDIF and USB, a Dark Vol-

ume screen with some additional information, and Dark Volume Details, showing all currently

active DSP functions.

Pushing the small encoder 1 or 2 cycles through them if any is currently active. To quickly call

them up simply press any of the four function keys one or two times. The remote can be used

for this as well after, assigning the command Toggle View to one of the four programmable

buttons (see chapter 14.1.1, Remap Keys).

15.1 Dark Volume / Details

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, the current reference level

setting, the amount of Bass/Treble gain applied and the

currently used input or source. 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 volume number is coupled to the over detection of the analog

outputs. It changes its color to red when overloads occur.

As with the other top screens, once selected it becomes the default screen, automatically

shown after power-up or when leaving a menu.

The Dark Volume Details screen displays some more information, like the currently used EQ

Preset, and any active DSP FX.

15.2 Analyzer

The Analyzer is based on RME’s famous Spectral Analyzer in DIGICheck. It uses 29 biquad

bandpass filters for high separation between the bands, providing outstanding musical visuali-

zation. Using carefully selected attack and release times the display is responsive, but still easy

to read. On top it uses RME’s own Max LR technique to prevent 6 dB higher level display for

monaural signals, and zero display with out–of-phase signals.

Thanks to the high-resolution IPS panel even smallest details are clear to see. Music content

analysis is possible even when viewed from a greater distance.

The Analyzer operates at any sample rate, and even with

DSD. There are no parameters to change, and the shown

frequency range is always the human audible range, 20 Hz

up to 20 kHz.

To be able to also show DC content the lowest band is not a

band-pass filter, but a low pass, catching the whole range

from 0 Hz up to 30 Hz. With some unusual signals it

therefore can happen that the level shown will be a bit

higher than expected.
