EMD-2 is SoundTraxx's second collection of EMD prime movers, covering the 567, 645 and 710 variants that the standard EMD profile leaves out. If you model a GP9, SD9, GP39, SD45, GP60, SD70MAC or any of the other locomotives listed below, this is the sound set built for it.\u003c\/p\u003e\n\u003cp\u003eTsunami2 combines a full sound system, Hyperdrive2 motor control, Hyperlight lighting effects and a DCC decoder on one board. A 32-bit processor drives 28 functions and 16 polyphonic sound channels, so the prime mover, horn, bell and brake squeal all play at once without cutting each other off. Dynamic Digital Exhaust reads the load on the motor and notches engine RPM up and down on its own, so pulling a heavy train upgrade actually sounds like work.\u003c\/p\u003e\n\u003cp\u003eThis is a universal, hardwire-style decoder measuring 35 x 18 x 6mm, sized for a wide range of HO and S scale diesels.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003ch3 class=\"sectionTitle\"\u003eWhich Locomotives Does the EMD-2 Sound Set Cover?\u003c\/h3\u003e\n\u003cdiv class=\"sectionContent\"\u003e\n\u003cp\u003eThe 885022 carries eight selectable EMD prime movers.
