DAC Board parts diagram: 1 DAC chip, 2 oversampling filter, 3 analog output stage, 4 crystal oscillator, 5 mute relay, 6 bare PCB, 7 SMD passive (R/C/L). 7 parts in 7 top-level items. — DAC Board parts diagram. Numbers match the table below; each box is one top-level part or assembly with what it contains.

#	Part	Qty	What it does
1	DAC Chip	1×	Stereo converter
2	Oversampling Filter	1×	Digital interpolation
3	Analog Output Stage	1×	Analog filter and buffer
4	Crystal Oscillator	1×	Master clock
5	Mute Relay	1×	Output muting
6	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.
7	SMD Passive (R/C/L)	1×	Surface-mount resistors, capacitors, and inductors, typically in 0402 to 1206 packages, that set voltages, filter noise, and time signals on a circuit board.
