Audio Output Stage

Assembly

Output section: a 24-bit DAC reconstructs the recovered audio, a balanced line driver feeds the XLR output, and a buffered 1/4-inch jack provides an unbalanced feed. A full specification article for this item is being written. Meanwhile its bill of materials and connections are below.

Audio Output Stage parts diagram. Numbers match the table below; each box is one top-level part or assembly with what it contains.
#PartQtyWhat it does
1 Bare PCB 1× Unpopulated printed circuit board: copper traces etched on an FR-4 glass-epoxy laminate that carry current between the components later soldered to it.
2 Audio DAC 1× 24-bit audio DAC
3 Balanced Line Driver 1× Balanced line driver
4 Connector 2× XLR output connector
5 SMD Passive (R/C/L) 30× Surface-mount resistors, capacitors, and inductors, typically in 0402 to 1206 packages, that set voltages, filter noise, and time signals on a circuit board.
