Overview
Headphone amp is an open-source printed circuit board by ildus, from the ildus/pangaea_cp16 repository on GitHub. It is a 2-layer board with 77 parts on 62 nets, routed with 435 tracks and 8 vias.
It is built around the NE5532 and BAV99. Its parts include 37 resistors, 26 capacitors, 8 connectors, 3 ICs and 2 diodes. It belongs with the audio and music boards of this library.
Main components
2README
README.mdCabinet simulator (on impulse responses) based on AMT Pangaea CP-16
Contains schematic and pcb. Based on debugging board of CP16.
Basic components.
- Pangaea CP-16
- NE5532D (3pcs) operational amplifiers.
- 0 Ohm 2512 SMD resistors
- 1206 SMD resistors
- 0805 SMD capacitors
- Electrolytic capacitors
- 15pin (pangaea), 4pin (pangaea control), 6pin (double potenciometer), and 2pcs of 2pin headers.
- 3pcs of 6.3mm audio jacks.
- 1pic of USB connector.
For the values of resistors and capacitors check the schematic.
Pangaea CP-16 (copied from AMT website).
AMT Pangaea CP-16 module lets you to emulate any Guitar Cabinet sounding by loading appropriate Guitar Cabinets’ Impulse Responses (IRs).
You can load up to 16 different Guitar Cabinets’ IRs in the module’s memory and choose the desired one in the right moment. You can load IRs in the CP-16 memory and control their parameters via USB.
Important note
As you can see on the image above, the pin header soldered on the side opposite to side with capacitor, that's not optimal and takes twice as much height. The PCB is designed to use with CP16 where pin header is soldered on the side of capacitor so the whole pcb can be put to usual aluminum case.

Questions
What parts does the Headphone amp use?
77 parts, built around the NE5532 and BAV99. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Headphone amp KiCad files?
From the ildus/pangaea_cp16 repository on GitHub, at the commit this page was made from: the board is headphone_amp.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Headphone amp design in my own project?
Its repository states no licence, so its author keeps all rights: ask ildus before reusing the design.
