It features a fully balanced differential input stage, differential phase splitter, and lower impedance push-pull output stage with a custom balanced output transformer. Incorporating VTL’s SmartTube technology, it offers automatic bias adjustment, fault sensing, and user-adjustable damping factor control for optimal loudspeaker matching. Additional features include zero global negative feedback, shorter feedback loop, current in-rush limiting, standby mute with reduced tube current, adjustable precision-regulated bias and screen supplies for stability, and comprehensive tube diagnostics with front panel LEDs. Designed for ease of use and sonic integrity, it handles complex dynamic signals with tonal stability and provides superior loudspeaker control.
