Woodland Scenics JS6958 Just Plug Automatic Trigger

The Woodland Scenics JS6958 Automatic Trigger fires a connected sound on its own, no button, magnet, or motion needed, making it one of the easiest ways to add background audio to a Just Plug Sound System setup. Three built-in modes let you repeat a sound continuously, play it at random intervals, or set a fixed frequency for how often it activates.

Indicator lights show which mode is currently active, and a stop button lets you silence the sound instantly, which is handy for a background loop that needs to pause during a demo or presentation. It's a strong fit for ambient effects on an HO scale model railroad, such as looping city traffic, industrial machinery, or nature sounds that shouldn't require a visitor to trigger them.

Pair the Automatic Trigger with a Sound Card and Mini or Micro Speaker for a self-running sound scene, or with a Stereo Splitter (JS6962) to fill a larger area.

Compatible with HO, N, O, and other model railroad scales.
