The WOW121 is a universal sound decoder for locomotives with DCC-ready 21-pin MTC connectors, and can also be used with any of TCS' motherboards. The WOW121 requires a motherboard to interface with the locomotive. The motherboard will determine the support for the number of lighting functions as well as the type supported (LED or 12V/1.5V bulbs). A WOW121 decoder will support up to 8 lighting functions.

Note: Function 5 and 6 are not programmable, and will only output constant bright lights. Take this into account when wiring multiple lighting functions.

For a complete list of available sounds, check out the "Sounds List" under the "Documents" tab.

  • CD-Quality Sound:
  • TCS' world-renowned CD-quality sound. 16 Bits of resolution at 44.1kHz sample rate.

  • Back EMF Load Compensation:
  • Provides superior slow speed control and high performance under load.

  • Quiet Drive:
  • Super-quiet motor control for "buzz" free motor performance.

  • DC Mode:
  • Decoder will automatically detect DC power. You can also configure how your lighting effects function on DC.

  • Variable Momentum:
  • Allows you to make custom acceleration and deceleration curves.

  • Function Remapping:
  • Buttons 0 through 12 may be used to control the lighting functions of this decoder.

  • Programmable Lighting Effects:
  • Choose from 20 separate user-programmable lighting effects!

  • Dimmable Brightness:
  • Configure multiple different brightness levels for your LED's or incandescent bulbs.

  • Decoder Lock:
  • Feature which prevents accidental/unwanted programming while activated.

  • Airwire™ Compatible:
  • Fully compatible with Airwire™ operation.

  • CAM:
  • Use a positive voltage trigger to synchronize your chuff rate to your drivers' rotation.

  • Audio Assist®:
  • TCS exclusive auditory feedback programming system. Program your decoder without the need to memorize CV's!

  • User-Loadable Speed Tables:
  • Configure custom speed curves and set speed limits.

  • Throttle Modes:
  • Choose from multiple throttle modes to meet your operating needs.

  • True Scale Sound:
  • A unique WOWSound feature which uses TCS’ exclusive auto-adjusting BEMF technology to automatically change the intensity of the chuff. Prototype Mode also offers dynamic sound volumes which accurately model the real-life equivalent. Also includes pre-programmed acceleration and deceleration values.
