Photos Active ABY amp switcher & Class-A buffer Isolated output eliminates hum and buzz 180° polarity reverse to phase-match amps Drag Control load correction for natural tone + More Features Active circuitry for noise-free switching The Radial Twin-City uses a class-A input buffer to drive the amp outputs, which reduces susceptibility to noise and allows for completely silent switching on stage. To eliminate hum and buzz from ground loops, the Twin-City is equipped with an isolation transformer on output-B, along with a ground lift switch and 180⁰ polarity reverse switch that ensures both amplifiers play back in phase with each other. At the input, Drag Control load correction allows you to recreate the natural load on the pickups as if you were connected directly to a tube amplifier, allowing the natural tone of your instrument to shine through.
