QSI Sound Decoders

The Titan Series has replaced the former popular QSI Revolution, Aristo and Magnum DC/DCC sound decoders. Generally the Titans appear similar to their predecessors. The new powerful custom sound processor enhances performance and features significantly, including a stunning STEREO output and 64 independent sound channels for unrivaled realism and much more. We now have received shipment of the second generation of Titans and are expecting even better performance and sound.

NOTE: We program the decoders for the sound file that you choose so you do not have to buy your own programmer. Your sound decoder comes to you ready to install!
