Schematics And Pcb Layouts - Bose ACOUSTIMASS 3 Manual

SCHEMATICS AND PCB LAYOUTS

The layout and schematic foldouts included with this manual can be used for Revisions 0
through 2 PC boards.
The Main PCB had a slight etch change from revision 0 to 1, and a reversed insertion of
diode D19, from revision 1 to 2. See the separate views for these etch and component
differences. The foldouts are arranged as follows:
• Main PCB schematic backed by component side and solder side PCB layouts
• Amplifier PCB schematic backed by component side and solder side PCB layouts
