ART took the legendary Tube MP series and updated every aspect of the design, inside and out, while still maintaining a compact, reliable, cost effective product, and added a USB output. From the new all-aluminum stackable chassis to the precision LED level metering circuitry, ART improved virtually every aspect of our already successful Tube MP series and added USB connectivity. USB (Universal Serial Bus) is a common hardware interface used for quick and easy connection of peripherals like the ART USB TUBE MP. The TUBE MP features a single Type B USB peripheral connector on the rear panel for outputting audio over USB to your computer. One of the nice features of USB is its Hot Swapping capability, allowing the Tube MP to be connected and disconnected without turning your computer off. The ART USB TUBE MP is fully USB 1.1 compliant, operating under Windows 98SEor newer, and Mac OS 9.1 or newer. The ultra low noise discrete microphone preamp front end has an extremely flat and wide frequency response and handles a wide range of input signal levels with a minimum of coloration. This gives you a very clean and neutral sound with a wide variety of signal sources. The high impedance 1/4 instrument inputs optimized for guitar pickups allowing every nuance to be heard. ART used a high quality 12AX7A tube inside to add warmth to musical dynamics and the power supply is external to keep AC line noise and hum back at the wall. The input Gain control and switch help you to maximize your input dynamic range as well as control how hard you are driving the tube. Input impedance is switch selectable to optimize your microphone s response right on the front end. These two features are a must when trying to get the most out of a vintage ribbon or studio grade micro Features: USB Interface Output with up to 70dB of Clean, Musical GainExtremely Low Noise Discrete Front End, XLR and 1/4 Inputs and OutputsHigh Output Signal Drive CapabilityFast FET Limiter to Prevent OverloadBuilt-in Low Noise Phantom Power Supply Product Details: Item Weight: 2.5 poundsProduct Dimensions: 11 x 7 x 3 inchesItem model number: 4330232872Is Discontinued By Manufacturer: NoDate First Available: April 13, 2004
