Soundtraxx Sierra Tips


Posted on Feb 5, 2014

This page describes the installation and use of a Soundtraxx Sierra sound system. The Sierra worked quite well and was reasonably priced, but time marches on. As of September 2008, the Sierra went out of production and was not replaced by an updated stand alone sound system. I purchased a Soundtraxx Sierra sound system to install in an Aristo C-16

(about $150 from Tony`s Train Xchange). The Sierra system is available with a ROM with recorded C-16 sounds. There are also ROMs for several other popular narrow gauge prototypes. As of June 2000, the Sierra is available with diesel sounds for Alco and EMD prime movers. I feel that the Sierra is the best value available overall in large scale sound system. The sound quality is at least equal to the much higher priced Phoenix system and it has more sound features, is more programmable and provides some lighting features as well. Its sound quality is MUCH better than the lower priced digital systems (Dallee and PH) but it costs only about $30 to $50 more. The Sierra works well with both DC track power and PWC track power. It integrates well with any kind of DCC decoder or R/C receiver with the addition of a few inexpensive external components. Overall, the Sierra sound system is quite good, but it has one really annoying characteristic. The track voltage controlled whistle triggers much too often, especially when PWC is used to power the track. There are adjustments that reduce the sensitivity of the triggering and eventually I did find a combination of settings that suppressed the voltage controlled grade crossing signal, so much so that I can`t even make it happen now. That`s OK, its better without the whistle signal. To realize the full capability of the system, you MUST pay careful attention to the treatment of the...
