ART TUBEMPUSBU Tube preamp with limiter and USB output

The Tube MP Project Series is a professional-grade audio interface designed to connect microphone, instrument, and line level signals to both digital audio workstations and analog devices. This updated iteration of the renowned Tube MP series boasts enhancements in every aspect, housed in a compact, durable, and cost-effective package, now featuring USB connectivity.

With a redesigned all-aluminum stackable chassis and upgraded precision LED level metering circuitry, we have elevated the performance of the Tube MP series while incorporating USB output capability.

Utilizing USB (Universal Serial Bus) technology, the ART USB TUBE MP facilitates seamless and efficient connection to peripherals. Featuring a single Type B USB peripheral connector on the rear panel, it enables audio output via USB to your computer. USB's Hot Swapping capability allows for convenient connection and disconnection without the need to power off your computer. The ART USB TUBE MP is fully compliant with USB 1.1 standards, compatible with Windows 98SE/ME/2000/XP/Vista, and Mac OS 9.1 or later.

Moreover, the newly integrated ultra-low noise discrete microphone preamp offers an exceptionally flat and wide frequency response, accommodating various input signal levels with minimal coloration.
