5. First Usage – Quick Start
5.1 Connectors and Controls
The front of the ADI-2 DAC has 3 hi-precision rotary encoders with push function, 4 buttons, a
standby power button, a high resolution IPS display, and two TRS headphone outputs.
The output channels Phones and IEM feed two phones outputs via two independent driver cir-
cuits, optimized for both high and low impedance headphones. Their unbalanced output signal
is of highest quality. With up to 120 dBA Dynamic Range there exists no audible hum and noise
at those outputs.
In case a phones output is to be used as line output, an adapter TRS plug to RCA phono plugs,
or TRS plug to two TS plugs is required.
The rear of the ADI-2 DAC has 2 RCA sockets as unbalanced outputs and 2 XLR sockets as
balanced outputs, TOSLINK optical/coaxial input, a USB socket, and a lockable power socket.
The short circuit protected, low impedance XLR line outputs do not operate servo bal-
anced! When connecting unbalanced equipment via XLR, make sure pin 3 of the XLR
output is not connected. A connection to ground might cause a decreased THD (higher
distortion) and increased power consumption!
Optical In (TOSLINK): The unit automatically detects SPDIF or ADAT input signals. Note that
only channels 1/2 from the ADAT stream can be accessed. SMUX and SMUX4 (up to 192 kHz)
are still supported.
USB 2.0 : Standard USB socket for connection to the computer. The ADI-2 DAC operates as
Class Compliant device, in 2-channel mode. It can be directly used with Mac OS X and iOS
(iPad, iPhone). For Windows the RME MADIface series driver adds WDM and ASIO.
Socket for power connection. This socket supports locking type jacks as found on the included
RME DC power supply. After inserting the connector carefully turn it by 90° so that it locks.
5.2 Quick Start
Connect the unit to the included power supply and push the red lit Standby button to start. The
ADI-2 DAC ships with Source Auto (I/O – Line Out – Settings - Source) as default setting.
Remove the transparent plastic isolator by tearing it out of the remote control bottom. Then use
the remote to switch to the desired input signal, USB, SPDIF optical or SPDIF coaxial.
Factory default for remote buttons 1 to 4:
1: Mono, 2: Loudness, 3: B/T Enable, 4: Dim
The ADI-2 DAC is a 2-channel I/O interface when connected via USB. Under Windows install
the RME WDM/ASIO driver to play back a stereo signal from the computer.
When not connected to USB the ADI-2 DAC will work as SPDIF to analog converter. In mode
Source Auto the input is switched to SPDIF automatically as soon as USB is no longer de-
tected.
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.
