Appendix IV: System Description
& Hardware Adjustments
The QS-2+ system consists of three circuit boards that plug into each other as
shown below. The bottom board is the QSI reverse unit (either an ACRU or
DCRU). The small, middle board, called the PS-1 Board, provides power for
the system. The top board, called the QS-2+ Microprocessor Board, controls the
system. It contains the computer and memory chip with software along with the
audio amplifier to produce the sound. Together, these boards provide the
realistic CD-like16 bit digital sound as well as computer and train control
features.
If you own a ProtoSound system converted to QS-2+, you have a two board
system:
The top board is very similar to the QS-2+ top board, except for a few missing
components. Converted ProtoSound systems work like QS-2+, but may not
accept all future QSI designed accessories.
The coupler board is included on the ProtoSound Bottom Board.
