About the MB-450 Series III Signature
The VTL MB-450 Series III Signature monoblock power amplifier features a fully balanced differential input stage, differential phase splitter, lower-impedance push-pull output stage, and fully balanced output transformer for improved loudspeaker drive capability. It includes switchable tetrode/triode operation, four levels of adjustable damping factor feedback for output impedance control, precision-regulated bias and screen supplies for stability under dynamic conditions, and microprocessor-controlled auto-bias, fault sensing, and protection circuits. Tube complement includes eight 6550C or KT-88 output tubes, one 12AT7 input tube, and one 12BH7 driver tube. Inputs are 1 pair RCA unbalanced and 1 pair XLR balanced; outputs are 1 pair binding posts. Designed for optimal performance with loads from 4-8 ohms, it offers exceptional transparency, dynamic range, and tonal balance.
