ART USB Dual Pre - An Affordable and Compact USB Interface/Preamp Combo!
Put simply, this is a perfect device for connecting a microphone (including condenser microphones that require phantom power) plus a guitar / instrument to any PC or MAC computer. The input jacks accept both XLR and TRS / TS connectors in the 1 socket!

With Audacity recording software included, you can record the 2 inputs (left, right) into separate tracks on your computer, to allow for accurate mixing and mastering after recording. Perfect for recording a vocal and guitar demo track, or building the base for polished recording.

The ART USB Dual Pre makes it easy and affordable to plug your mic or audio source into your computer. The USB Dual Pre packs a fully-featured dual preamp and a USB interface into a very compact, tough housing. This unit can use your computer for USB power, or you can use a 9-volt battery or an external 12-volt power supply (sold separately). It features two combination XLR/1/4" TRS inputs, phantom power for up to two mics at a time, a mini headphone jack, and two balanced 1/4" outputs (these can be used to go to your speakers or as preamp outputs). Independent channel gain, monitoring, and mix controls are also included on the USB Dual Pre.

Made For a Variety of Applications
ART's USB Dual Pre is designed to work over a wide variety of applications, from remote field recording to desktop/studio tracking. Each of this unit's two low noise input channels has up to 48dB of clean gain with signal present and clip LED indicators. Inputs can be either XLR balanced or 1/4" / 6.35mm, either balanced (TRS) or unbalanced (TS) .The 1/4-inch Input connections are used for instrument or low line level balanced or unbalanced signals. The high fixed input impedance works well with guitar and other passive instrument pickups. You can use an unbalanced or balanced plug with this connection.

Mobile or Desktop Recording
The USB Dual Pre is powered via the USB bus. An internal 9-volt battery or an optional external 12-volt power supply (or any combination of USB, battery, and power supply) can be used, depending on application. When running powered by battery alone, you should expect in excess of 50 hours of operation with phantom power off. Battery life will drop to approximately 20 hours (depending on microphone) when phantom powering is engaged (still enough time to get through an average session). The built-in low noise +48 Volt phantom power supply allows you to power up to two microphones as well as the preamplifier when running from any power sources, including the USB bus.

Flexible, Latency-free Monitoring Options
For monitoring, an 1/8" TRS mini headphone jack with level and monitor mix controls on the rear of the USB Dual Pre allow for latency-free local monitoring of the inputs while recording as well as playback monitoring of the USB bus. The monitor mix is also routed to the 1/4" TRS balanced outputs. This lets you use the USB Dual Pre's 1/4" outputs as either preamplifier outputs or as the monitor feed to your powered monitors.

Plug-and-play USB interface
The USB interface that's built into the USB Dual Pre is fully compliant with USB 1.1 specification and uses USB adaptive mode for playback and USB asynchronous mode for record. It will work with the USB audio device drivers built into Windows 98SE/ME/2000/XP/Vista and Apple OS9.1/OSX computers with native USB support. No special drivers are needed. Plus, the USB Dual Pre comes complete with Audacity recording and production software.
