The USB Dual Pre from ART is a combination portable preamplifier and computer interface, housed in a compact rugged case. The unit is suitable for a wide variety of applications including remote field work to desktop/studio recording. The 2 input channels can accept either a microphone or line input and provide up to 48dB of gain.

Phantom power is available for use with condenser microphones even when running from the USB bus or any of the other powering options. Those include using an optional external power supply, or an optional internal 9V battery. When running off the battery, operational hours are in excess of 50 hours with phantom power off.

A stereo mini headphone jack is provided for monitoring and the rear level and monitor mix controls allow for latency-free recording. The monitor mix is also routed to the main outputs. The USB interface is fully compliant with the USB 1.1 specification and uses USB adaptive mode for playback and USB asynchronous mode for record.
