TOSLINK Fiber-Optic Audio Output Add-on Module for AmpPRO
APA-TOS1
connects to a 12-pin, 2-row connector inside the AP4 or AP5 housing, on the main circuit board.
Connect a standard TOSLINK cable between the AmpPRO, and your high-end DSP (Digital Signal Processor) or
components.

Installation
Note the location of the LED lightpipes, in reference to the RCA connectors. This will be important,
during reassembly.
1) Carefully open the AmpPRO housing. This can be easily done by holding the module upside down.
outward, while providing pressure with your thumbs on the top cover.
This will release the locking tabs on the ends of the housing, allowing you to remove the top cover.
2) Once the top cover is removed, you will have access to the end plates.
Simply pull upward on the end plate featuring the RCA conenctors.
This will allow the main circuit board to be removed from the plastic housing.
Once the circuit board is removed, the APA-TOS1 can be attached to the board.
3) NOTE! The APA-TOS1 module is shipped with a small piece of foam covering the pins, to protect
them before installation.
THIS FOAM MUST BE REMOVED BEFORE INSTALLING THE APA-TOS1 into the AmpPRO.
4) Locate the 12-pin, 2-row header (black plastic connector) at the end of the main circuit board.
Carefully press the APA-TOS1's pins down into this header, so the OSLINK output is exiting the T
housing next to the RCA connectors.
The OSLINK output should align with the RCA connectors, however it will be slightly recessed, in T
comparison.
There is a small square knock-out door near the far left end of the plastic end cap. This knock-out
covers the hole before the APA-TOS1 is installed. Carefully score the edges of this knock-out, and
Fit both plastic end plates back onto the main circuit board. Then carefully seat the board, and end
channels in the bottom cover.
6) Reinstall the top housing cover. A "click" will be heard when the top latches with the bottom.
Installation is now complete, and your AmpPRO module's TOSLINK output is ready for use.
