Quick Start; Operation At The Unit - RME Audio ADI-2 Pro User Manual

5.2 Quick Start

Connect the unit to the included power supply and push the Standby button to start. The ADI-2
Pro ships with Basic Mode Auto (SETUP – Options – Device Mode – Basic Mode) activated.
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 digi-
tal 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 sig-
nal 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 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.

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 screen's header shows both the currently selected
output as well as the current hardware reference level (Ref
Lev, see chapter 12.2.1).
The EQ is set up either directly within the I/O menu structure (turn encoder 2 to access Set-
tings, 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
parameter 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. The EQ can be enabled in the second menu which comes up by push-
ing the EQ key a second time.
