Rolling Thunder Receiver

(Note: this item is the receiver only. If you prefer to use your own RCA equipped subwoofer, you may choose to purchase this receiver to play the full frequency sounds from your Paragon3 and Paragon4 equipped locomotives.)

We are still amazed by the realistic sounds our models can produce. Yet, when we hear a real locomotive, we notice the deep rumbling sounds that even our advanced model locomotives simply cannot reproduce. Until now.

Our Paragon4 with RollingThunder sound and control system for HO and N scales has all the features of its predecessors, but now includes more higher fidelity sounds than ever before, plus the ability to reproduce low frequency sounds that will give your railroad the feel and depth of sound of a real locomotive!

How does it work? The speakers in most HO scale locomotives will only reproduce sounds above approximately 600 hertz. Speakers for N scale reproduce sounds limited to even higher frequencies. The human ear can detect sounds between 20 to 20,000 hertz, and we can feel sounds at even lower frequencies. Many of the sounds real trains make are in the lower frequencies that models cannot reproduce. This is due to the tiny speakers which cannot move enough air. To overcome this shortcoming, Paragon4 incorporates a cutting-edge radio transmitter system we call Rolling ThunderTM that sends the low frequency sounds to a specially designed receiver and subwoofer under your layout. Since low frequency sounds have a longer wavelength, it is difficult for the human ear to detect the direction of the source. The result is that while the locomotive moves around your layout, you can hear the high frequency sounds coming from the locomotive, and the low frequency sounds from the subwoofer - - all perfectly synchronized to the motion of the locomotive and the puffing of the smoke. Your ears will perceive the full array of the sound as coming from the model!

On a large layout, where a locomotive can be very far from the subwoofer, the Rolling Thunder system detects the distance and fades out the subwoofer until the locomotive gets close again. If another locomotive is in range while the RT Receiver is not connected to the first locomotive, this new locomotive will connect automatically to the RT Receiver and the subwoofer will begin playing its sounds at levels appropriate to its distance to the subwoofer. The sensitivity setting can be customized by the user to maintain bass sounds throughout the entire layout.
