Designed as the ideal preamp for any application, the tube driven TPS II add warmth and texture to any audio source. These two-channel high performance preamps use a pair of hand selected 12AX7A tubes in the low noise input circuitry. This, coupled with ART’s proprietary V3 (Variable Valve Voicing) and variable input impedance allow the TPS II to deliver incredible performance from cost effective single space rackmount solutions.V3 TechnologyV3 provides optimized reference points to begin the recording process. The V3 presets were created and fine-tuned by some of the industry’s top studio and live-sound engineers. V3 technology allows you to select between a multitude of presets designed for guitars (electric and acoustic), keyboards, bass guitars, drums, vocals and more.Variable Input ImpedanceVariable input impedance increases the sonic potential of the TPS II even further. It delivers entirely new sonic textures and tone by varying the input impedance of the preamp, which in tur
