Reply to "MTH Proto Sound by QSI verse PS 1 and PS 2"

The QSI Set up was three boards sandwiched together. MTH had there version made as a 2 board set. QSI evolved with great amount of conventional options such as the ability to assign ID and Road Names to the engine controlled by a sequence of bells and whistles. MTH does not have that capability as they transitioned into PS-2 full command control.

Sounds and basic features of PS-1 and QSI are the same. Most MTH boxes say QSI but it is MTH production version. If an engine has full QSI system, it was either a different manufacturer or owner upgraded to QSI for those extra conventional features. QSI system is no longer supported. MTH system is, as parts still available, though no longer being manufactured. G
