. . . Many assume full Tsunami which it is not. I see this issue every so often in different train forums. It is a SoundTraxx decoder with Tsunami technology.
. . .

Some of the Bachmann Spectrum line locomotives are factory equipped decoders with Tsunami technology. However, technically the Sound Value decoder does not have Tsunami technology. The Sound Value does have some of the technologies used in a Tsunami decoder like SoundTraxx Hyperdrive, Hyperlight and true polyphonic sound. Do not conclude from this that the Sound Value decoder is an inferior digital sound decoder.
