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.

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.
