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.
- HD-Quality Sound: TCS=WCS (TCS=World Class Sound). Best sound on the market. 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.
- Variable Momentum: Allows you to make custom acceleration and deceleration curves.
- Incandescent Bulb Support: This decoder can be used with 12 Volt bulbs.
- 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.
- 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.
- Proto Notch™: A WOWSound original feature which uses TCS’ exclusive auto-adjusting BEMF technology to automatically choose the active notch sound. Prototype Mode also offers dynamic sound volumes which accurately model the real-life equivalent. Also includes pre-programmed acceleration and deceleration values.

Speaker Selection
- This decoder is optimized for 8 Ω speakers (not included).
- This decoder uses and audio amplifier capable of supplying up to 2 Watts of power to an 8 Ohm load at maximum volume. An 8 Ohm speaker with a 1 Watt minimum power rating is recommended for use with this decoder as it comes out of the package. If you are using an 8 Ohm speaker with a power rating of 2 Watts or less, you must reduce your master volume to prevent speaker failure or amplifier stress.
- The amplifier(s) on a WOWSound product can support speakers with impedance ratings as low as 4 Ohms. A reduction in impedance will require a higher power dissipation rating (more Watts) on said speaker. The minimum power requirement for a 4 Ohm speaker is 4 Watts. If you are using a 4 Ohm speaker with a power rating of 4 Watts or less, you must reduce your master volume to prevent speaker failure or amplifier stress.
- Speaker enclosures greatly increase speaker performance in most cases - improving the apparent volume by more efficiently directing the flow of air and reducing or eliminating destructive interference.
