ART TUBEMPU Tube preamp, Original Edition

ART's TUBE MP incorporates a hybrid circuit design that leverages cutting-edge solid-state and tube technologies. Employing a transformerless design ensures outstanding signal integrity and minimal noise throughout. The active balanced input features a hybrid configuration of paired transistors and op-amps, delivering exceptionally low noise and high common-mode rejection ratio (CMRR).

The instrument input boasts high impedance to prevent loading of connected devices. Phantom power is sourced from the incoming AC voltage. Additionally, the XLR output is active balanced, while the ¼-inch output is unbalanced with a 300-ohm impedance.
