SoundTraxx is an American company which designs and manufactures Digital Command Control decoders and accessories.

They were formerly known as Throttle Up!


Throttle Up! Corp., was founded in 1989. Their first product was called the Hyperlight. The Hyperlight was the first lighting system using a microcontroller, allowing user selected effects.

In 1991 they offered a Diesel sound system that was operated wirelessly, a steam module followed.

In 1994 they began selling the DSD series sound decoder, the first DCC decoder with sound built in. It also offered offered a multi-voice feature, where one sound wouldn't interrupt another,

As the SoundTraxx brandname became better known than the company name, they decided to use the Soundtraxx brand exclusively in 1998. (JMRI's DecoderPro referred to Soundtraxx products by the name Throttle Up! until recently.)

SoundTraxx manufactures the Tsunami Digital Sound Decoder. Versions of these decoders are also popular as OEM decoders. A new product is the Tsunami motor only decoders. They also make the Soundcar sound only decoder which can be installed in a boxcar, from N to G scale.
