SoundTraxx 840001 SurroundTraxx DSP-80 DCC Sound System

SurroundTraxx is a major breakthrough in sound system for model trains! For the first time, a sound system has been designed with multiple trains in mind. SurroundTraxx gives you the realism of high-fidelity sound moving with the train as it travels about the layout without installing speakers onboard the engine.

SurroundTraxx begins with a multiplicity of audio speakers that are strategically placed in hidden locations around the layout. Using the latest Digital Signal Processing (DSP) technology and advanced block detection techniques, SurroundTraxx faithfully reproduces the sounds made by each train on the layout and directs the sound to the speaker closest to the train's location. As a train moves along its route, SurroundTraxx makes continuous adjustments to the sound level of each speaker so that the sound appears to follow the train around the layout.

SurroundTraxx does not simply switch the sound from speaker to speaker but uses an intelligent cross fade algorithm that factors in train speed, direction, and distance between speakers. The sound makes a smooth transition as your train travels from one sound zone to the next without abrupt pops or thumps.
