PI2AES FAQ - Frequently Asked Questions
Q: Do the PI2AES outputs work simultaneously?
A: Yes, all digital audio outputs deliver the same audio data at the same time. This includes the buffered I2S and I2S over HDMI.
Q: Is the PI2AES compatible with the new Raspberry PI 4?
A: Yes, the PI2AES has been tested on the PI 4 using Moode Audio version 6.10.
Q: Does the PI2AES power the PI?
A: Yes, the PI2AES delivers 5V @ 3A to the PI. A jumper plug (marked PI5V) on the PI2AES allows the power to the PI to be enabled or disabled as desired.
Q: Can I power the PI separate from the PI2AES.
A: Yes, simply remove the PI5V jumper plug and provide power to the PI via it's usb power input as normal.
Q: What happens if I forget to remove the jumper?
A: Nothing bad! The PI2AES contains a protection circuit that allows both sides to be powered separately. It does mean that if the PI power supply is less than the output from the PI2AES, the PI2AES will still provide the power to the PI.
Q: What power supply do I need for the PI2AES?
A: The PI2AES is designed to operate with an input voltage 24V (+/- 10%). We sell a High Quality Meanwell 24V @ 2A supply specifically for the PI2AES.
Q: Are there two different acrylic cases for the PI4 and PI2/3?
A: The acrylic case we provides has two different right side and front plates for the PI2/3 and PI4. You just assemble which one is appropriate for you.
Q: What is the purpose of the jumper on pins 13-14 of the 16-pin I2S Header?
A: This jumper enables the internal PI2AES Power Switch. External add-on boards will have their own power on mechanism and this jumper would then be removed.
