Product Description
ART’s TUBE MP circuitry is a hybrid design utilizing the latest and best solid state and tube
technology, Using a transformerless design throughout the TUBEMP maintains exceptional signal integrity and extremely low noise. The active balanced input utilizes a hybrid multiple paired
transistor/opamp design providing extremely low noise and excellent CMRR. The instrument input
has a high impedance preventing the loading of any device connected to it. Phantom power is derived from the incoming AC voltage. The XLR output is active balanced and the ¼-inch output is
unbalanced with a 300 ohm impedance.
