Connecting the XMC-1
Using The UsB stream Input (the Computer/DAC Input)
The USB Stream Input on the XMC-1 is used to connect the USB digital audio output of a device
like a computer or other computer-based USB audio source. Connect your computer to your
XMC-1 using a good quality commercial USB cable. Avoid using cables over two meters in
length, and avoid unusual "audiophile" cables that may not comply with standard USB data cable
specifications.
Note: This input requires a source device that supports UsB Audio Class 2 (UAC2). The XMC-1
will appear as an external UsB audio device to computers connected to this input. Modern
Apple computers support this type of device directly (without any additional drivers); Windows
computers will require you to load a driver on the computer (we provide the driver); other
operating systems (like linux) may or may not support this type of connection. you CANNoT
connect a UsB stick or UsB hard drive to this input.
The XMC-1 will appear as a USB audio device (sound card or speaker) to a computer that is
connected to this input. Like most audiophile DACs, this input supports two-channel PCM audio
at sample rates between 44.1 kHz and 192 kHz at 16 bit or 24 bit depth, and does NOT support
most multi-channel digital audio formats, including multi-channel PCM audio files or DSD.
However, it DOES support playback of DTS encoded CDs and audio files (including both two-
channel and surround sound types).
Most modern Apple computers have the drivers required to support this type of connection
built in. For Windows based computers, you will have to download and install the appropriate
drivers. The drivers can be downloaded from the Resources tab on the XMC-1 product page of our
website. Instructions for installation can be downloaded from the same location.
Note: The most efficient way to install these drivers is to download and extract the drivers, start
the driver setup procedure, and then connect your XMC-1 to the computer when the driver
setup program prompts you to do so. If you connect your Windows computer to the XMC-1
before installing the drivers, your computer may attempt to automatically download and
install drivers from the Internet. If it does so, the automatically downloaded drivers will not
work. If this happens, there is no need to remove the incorrect drivers; simply install the correct
drivers and your XMC-1 should automatically use them and work as expected.
