Schiit Asgard 3 Second Input Faceplate

Description/Background:

This is an insert for the Schiit Asgard 3 headphone amplifier that securely holds two panel mount RCA jacks. The Asgard 3 can be purchased with a DAC input card that connects to an internal header on the mainboard, and the user can then toggle between the DAC or standard RCA inputs using a front panel switch.

Many users opt to not buy the DAC module, leaving a functionally useless front panel switch and a blocked off rear panel cutout. But, by connecting a couple of RCA connectors to the left channel, right channel, and ground pins of the internal header, you now have a usable second line level input.

Parts needed:

Besides this 3D printed faceplate, you'll also need:

• CUI Devices RCJ-032 (red plate mount RCA jack)
• CUI Devices RCJ-033 (white plate mount RCA jack)
• M3 screw (or similar size screw)
• Wire
  • Doesn't have to be anything fancy. I've found that 22 gauge wire works well, as it fits in the header securely. Breadboard jumper wires also work great.

Instructions:

Dissassemble your Asgard 3 by first pulling the front panel knob forward, then removing the nut that secures the potentiometer to the chassis. Remove the four screws from the top of the Asgard, and finally pull the cover forward so it clears the potentiometer and switches. 

Screw the RCA jacks onto the 3D printed faceplate, then solder wires to the center terminal (positive) and ground tab. 5 inches is a pretty good length for the wires. Push out the “Optional Input Card” sticker, and insert the faceplate (with attached RCA connectors and wire) at an angle so that the chassis metal ends up in the groove between the front of the panel and the rear. Use a M3 screw to tap and secure the faceplate. Then, connect the wires to the header by your chosen method, using the photo in the gallery that points out which pins are for which signal.

Print settings:

No special print settings needed, 20% infill, with supports, and at 0.2 resolution is fine. Orient the .stl so that the tube for the screw if facing upwards and away from the build plate.
