In Windows XP & Mac OS X (10. 2. 6 & higher), the MobilePre USB is class-compliant, making driver installation optional--to begin using the MobilePre USB, you may simply plug the unit into a USB port . However, choosing to install the driver will allow the following added functionality: Windows XP - Device Control Panel and ASIO support with low-latency drivers Mac OSX - Device Control Panel and Direct Monitor control with low-latency drivers NOTE: For easiest setup, you should install the software drivers on the included CD-ROM before connecting the USB cable to your computer. [. . . ] MobilePre USB Outputs The rear panel of your MobilePre USB has two sets of outputs: a pair of 1/4" jacks (labeled Output 1 & 2) and a single 1/8" stereo jack (labeled Stereo Line Output). Either of these outputs can connect to a set of powered speakers for monitoring. You can also connect the outputs of the MobilePre USB to a mixer or a stereo receiver. Use whichever set of outputs fits the inputs of your monitor system, but you should only connect one or the other. If your speakers or receiver uses RCA jacks instead, you can purchase a converter, like the one pictured here, at an electronics store such as Radio Shack.

You can then connect the power amp or receiver's outputs to the speakers. Make sure that the speakers that you use near a CRT Computer Monitor are shielded speakers. [. . . ]
