5.2 Quick Start
Connect the unit to the included power supply and push the Standby button to start. The ADI-2/4
Pro SE ships with
Basic Mode Auto activated ( SETUP
– Options – Device Mode / DSD – Basic
Mode ). The input selection for SPDIF (coaxial or optical), and the source selection for Phones
Out 3/4 are also set to Auto, the SRC is activated for the SPDIF input. With Auto active the unit
will turn into different modes depending on connected cables:

Preamp : Analog in to Analog out (internal digital out to in). This mode is active when no digital
input signal and no USB is detected.

AD/DA : Converter Mode, analog in to all digital outs, digital in to all analog outs. This mode
becomes active as soon as a digital signal is attached. This signal will also become the signal
source. In case more than one digital signal is found the user has to manually select the source
to be monitored. The SRC is active as default and assigned to SPDIF. Clock mode is slave to
AES in, but will adapt to the detected source (Auto).

USB : or interface mode (also USB DAC). If USB is detected all inputs are routed to USB, all
outputs are fed from USB. USB has priority over the converter mode. In Setup the unit can be
configured as 2- or 8-channel device. In most cases 2-channel will be the better choice.
USB can be manually overridden by selecting a different mode. This will change the I/O routing,
but not disable USB itself. All inputs are still available via USB, outputs 3/4 can playback USB. In
all modes except Basic Mode
DAC output PH 3/4 is freely configurable, any possible source can
be monitored independently from outputs 1/2.
The unit remembers all settings, and loads these automatically when it is switched on again. To
switch off, press the Standby button for at least 0.5 seconds.
5.3 Operation at the Unit
Useful information for a smooth start:
Turning the big VOLUME knob brings up the Volume screen
of the currently selected output. Pushing the big Volume knob
changes the volume setting between Outputs 1/2 and 3/4.
The status bar at the bottom of the display shows the current
dB value of both volume settings. A white rectangle around it
(marker) indicates which volume the big encoder is currently
set to control.
The header shows the currently selected output as well as
hardware reference level (Ref Lev, see chapter 12.2.1).
The EQ is set up either directly within the I/O menu structure (key I/O, turn encoder 2 to access
Settings, Parametric EQ, Bass/Treble and Loudness), or via the graphical EQ screen which is
shown after pressing the EQ key. In this screen the cursor has three positions: top*, the EQ pa-
rameter line below the response curve, and filter selection type for band 1 and 5 (Peak, Shelf,
Low/High Cut). The cursor is moved up or down by pushing encoder 1 or 2. When in the EQ
parameter line, all values are no longer grayed out. In this state the big encoder steers Gain,
encoder 1 Frequency, and encoder 2 Quality factor. This way the EQ is extremely fast set up and
edited.
The graph has 5 different colors matching the 5 bands that can be adjusted. If the line is just grey
the EQ is disabled (bypass). The EQ can be enabled in the second menu which comes up by
pushing the EQ key a second time.
