WOW121-Steam

Decoder
SKU: 1525
Description

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.

  • 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!

    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.
