Soundtraxx DCC Mobile Decoders MC2H104AT

SoundTraxx DCC Mobile Decoders – MC2H104AT are non-sound, board-replacement motor decoders designed specifically for select Atlas HO scale locomotives. The MC2H104AT replaces the factory light board, providing smooth DCC motor control and reliable lighting functions without adding onboard sound.

Atlas Board-Replacement Mobile Decoder

The MC2H104AT is engineered to match the factory light board footprint used in many Atlas locomotives. This board-replacement design simplifies installation by aligning motor and track contacts while still providing the benefits of SoundTraxx motor control technology. Soldering may be required for lighting connections depending on the locomotive model.

Non-Sound DCC Motor & Lighting Control

The MC2H104AT is a mobile (non-sound) decoder, meaning it controls speed, direction, and lighting functions but does not generate sound. If you are looking for sound-equipped decoders, explore Tsunami2 digital sound decoders, Econami digital sound decoders, or Blunami digital sound decoders.

Smooth Motor Performance & Function Outputs

SoundTraxx mobile decoders are designed to deliver smooth starts, excellent low-speed operation, and consistent throttle response. The MC2H104AT supports lighting and function outputs for headlights and additional lighting effects based on the locomotive’s wiring and board configuration.
