WOWSound is the original "Full Throttle" Diesel Decoder

We call it "Manual Notching" but it is essentially the same feature. This feature is on every WOWsound diesel decoder ever made. This includes version one of the WOW diesel decoder released January 2015.

Manual Notching allows you to independently adjust the prime mover sound or "notch sound", and separately control the speed of the locomotive. TCS Manual Notching works very simply without any set up.

Here is how to do it.

Using the throttle, you set the desired speed of the loco, and by using the Manual Notch up button (10) and Manual Notch down button (11) you can change the notch sound to the desired notch! Yes it is that simple! The notch sound you manually select locks in and overrides the throttle selected notch setting. Manual Notching is available full time in all throttle modes.

When you change the throttle the decoder automatically takes back control and sets the appropriate notch sound. To override the decoder's selected notch setting simply use the Manual Notch up and down buttons at any time. Manual Notching overrides the automatically selected notch sound. You can notch up before you even move the locomotive!

By default, TCS "Manual Notch Up" is button ten, and "Manual Notch Down" is button eleven; However, if Manual Notch mode is something that you would like to use often then we recommend you re-map the Manual Notch buttons to three and four respectively. Moving the notch buttons to buttons three and four makes it more convenient to access them on most throttles compared to the default of buttons ten and eleven.

This can be done very simply through Audio Assist™, no need to ever program a CV. Press button 8 four times rapidly when your locomotive is at a stop to access Audio Assist™ and walk through the process.

Ultimately, the most fun, premier, and realistic way to notch your locomotive is to allow the exclusive TCS Auto-Notching feature control the notch sound. The decoder automatically sets the notch according to the load, not the speed. Real life locomotives could be in notch eight yet crawling at slow speed because of a heavy train and steep grade. Your TCS decoder by default is configured to Auto-Notch giving you the correct load-based sound! The decoder does this by measuring the load on your locomotive and calculating the required power to move that load. It is awesome to experience TCS' Auto-Notching in action, offering the most realistic operational experience possible of any decoder on the market. Auto-Notching is a TCS exclusive feature! There is even a simple way to calibrate the Auto-Notching feature for your locomotive using Audio Assist™. Your TCS decoder will Auto-Notch without doing the calibration, but the calibration is there to customize exactly how you would like to hear your locos working on your railroad.
