DALLEE #1102 AC SOUND CONTROLLER; ELITE model, 10-amp . The Elite Edition of the Dallee AC Sound controller features special technology that prevents a voltage drop on the track when a button is pressed. Other brands will drop the voltage on the track when one of the buttons is pressed, slowing the train each time it is used. The AC Sound Controller is used to control the Horn or Whistle and Bell functions on most AC style locomotive sound systems, but will not replace any original Gilbert sound controls such as the Air Chime Whistle or Diesel Horn controls.

The original #1101 control is still available (SKU #00536) , features the same sound controls, but will cause a slight voltage drop to the track when operated.
