ART USB DUAL PRE Project Series Digital Audio Interface

The ART USB Dual Pre Project Series is a compact two channel mic, line and instrument preamp with a built in USB audio interface, designed to let you capture great sounding recordings wherever inspiration strikes. With flexible power options, proper analogue controls and true zero latency monitoring, it is equally at home in a desktop studio, rehearsal room or thrown in a gig bag for location work.

Each channel features a robust combo input with up to 48 dB of clean gain, so you can plug in microphones, line level sources or instruments and get them up to recording level quickly and easily. Class compliant USB connectivity keeps setup simple, while the rugged metal enclosure protects your interface on the move.

Portable Two Channel Recording Rig

The USB Dual Pre gives you two independent preamp channels in a footprint small enough to sit on a pedalboard or laptop stand. With combo XLR and 1/4" inputs, you can track vocals and guitar, a stereo keyboard, or a compact live setup without needing extra boxes. It is an ideal solution for songwriters, podcasters and engineers who need reliable two channel recording without carrying a full sized interface.

Flexible Power for Mobile Sessions

Power the interface directly from your computer via USB, run it from a 9 volt battery, or use an optional external adaptor. This flexibility makes the USB Dual Pre particularly useful for remote recording where mains power is limited or where you want to reduce the power draw on a laptop or tablet. With up to around 20 hours of battery life with phantom power engaged, and over 50 hours without, you can comfortably handle extended sessions away from the studio.

Zero Latency Hardware Monitoring

A dedicated blend control on the rear panel lets you mix the direct input signal with audio returning from your DAW over USB. This gives you true zero latency monitoring, so performers hear themselves in real time without distracting delay, while still being able to balance in backing tracks or click. A separate level control for the 1/4" outputs and headphone output keeps monitoring levels easy to manage.

Simple, Driver Free USB Connectivity

The USB Dual Pre is class compliant, so it works as a standard USB audio interface without needing special drivers. This keeps installation straightforward and makes it a practical choice for multi computer setups, education environments or anyone who wants to plug in and start recording quickly. With 16 bit resolution at 44.1 kHz or 48 kHz, it delivers clean, reliable audio quality for music, podcasting and content creation.

• Two Channel Mic, Line and Instrument Preamps - Dual combo XLR and 1/4" TRS inputs with up to 48 dB of gain let you connect microphones, line level gear and instruments, making it easy to capture vocals, guitars, keyboards and more with one compact unit.
• Zero Latency Hardware Monitoring - The dedicated blend control allows you to mix direct input with USB playback for real time monitoring without delay, helping performers stay comfortable and in time while recording.
• Multiple Power Options for Mobile Use - Operate the interface from USB bus power, a 9 volt battery or an optional external adaptor, giving you the freedom to record in locations where mains power is limited and to reduce strain on your host device.
• Class Compliant USB Audio Interface - Driver free operation at 16 bit, 44.1 kHz or 48 kHz sample rates keeps setup simple across compatible systems, so you can move quickly between different computers and recording environments.
