CONNECTIONS
The 1/8-inch MONITOR HEADPHONES is stereo TRS jack. It can accommodate
a wide variety of headphone models. Maximum output level is 150mW.
The USB port is USB 2.0 compliant and should be used to connect directly to
one of the USB connections on your computer. This connection also powers the
USB circuitry inside the
USB-DI Project Series . To your computer this connec-
tion looks like a “USB Audio DAC” and your computer then controls the sample
rate.
Since the USB connection will be carrying high quality digital audio to and from
your computer as well as bus powering the USB interface, we suggest that you
use a high quality shielded USB cable for best performance. Ideally you should
connect directly to one of the USB ports on your computer. Connecting through a
shared hub can reduce power and bandwidth that is available for each USB
device and should be avoided when possible. Though the
USB-DI Project
Series is compatible with USB 1.1 and 2.0 interfaces, USB 2.0 is preferred for
the cabling and computer connection as it allows for more system bandwidth.
The XLR LEFT and RIGHT analog Outputs can be connected to a variety of line
level input products a few examples would be a mixers, receivers, or powered
speakers.
NOTE: Before connecting the USB-DI box XLR OUTPUTS, make sure all audio levels are
turned down or the system is not powered on. This helps to prevent any popping issues
that would damage more sensitive equipment. It also helps to be in Variable output mode
with the volume control fully CCW before powering up if connected to an audio system.
