Connecting Audio Source Units
The XDA-1 DAC preamplifier can connect to up to six different audio devices, using standard XLR connector
for the AES/EBU input, standard RCA analog connectors for coaxial inputs, Toslink connectors for optical
inputs and USB type B to A connector for USB input .
AES/EBU
Connects to an AES/EBU source using XLR cables.
OPTICAL (OPT1 & OPT2)
Connects to an optical S/PDIF source using a Toslink optical cable.
COAXIAL (CO.1 &CO.2)
Connects to a S/PDIF source using a 75 ohm coaxial RCA cable.
USB
Connects to a USB audio interface using a standard USB type B to A cable. After the connection is made the
operating system detects it as a new hardware device. Modern operation systems like Windows XP, Vista,
Windows 7, Mac OS and Linux detect the hardware directly and install the correct USB audio automatically.
Note: Do not exceed 2 meters in cable length. Cable quality is critical to ensure reliable operation.
Audio Applications
Under Windows XP, Windows Vista and Windows 7 the XDA-1 can be selected as an audio output device
under
Control Panel > Hardware and Sound> Sound
.
Under Mac OS X, you can select and configure the XDA-1 via the MIDI Setup application that can be found in
your application folder.
The XDA-1DAC preamplifier is a playback device and can replace your on board soundcard fully for all stereo
playback functions.
Connecting To Amplifiers and Speakers
When connecting to amplifiers and speakers, make sure to use the properly labeled left and right channel
connections.
Check to make sure that you have connected the proper cables in the proper sequence.
DIFFERENTIAL (BALANCED) OUTPUTS
Left and right channel XDA-1 line balanced outputs into either the left and right balanced inputs of your
amplifier or preamp.
UNBALANCED OUTPUTS
Left and right channel XDA-1 line RCA outputs into either the left and right balanced inputs of your amplifier or
preamp.
Note: For highest performance and noise immunity, always use high quality, 100% shielded cables.
TRIGGER CONNECTIONS
5-12VDC trigger input and output are used to remotely trigger the XDA-1 or a connected device on and off.
Please ensure that the total of the loads connected to this trigger do not exceed 500mA.
