The WOW501 is a universal, 5 Amp sound decoder for large-scale locomotives. The WOW501 includes Keep Alive® on-board for stutter-free operation. Function 5 and 6 may be programmed to control a smoke unit with a coil and fan. By programming CV58 with a value of 9, the smoke unit will react to the chuff timing.

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.

 Keep-Alive®: Included on-board for smooth, stutter-free operation.

 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.

 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.

 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.

 Chuffinity By combining a massive library of chuff sounds with a state of the art algorithm, Chuffinity produces a beautiful chorus of chuff sounds without ever producing a looping or predictable pattern. Beautiful, clear, and complex chuffs that never repeat will take you trackside to the days of steam glory!
