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. But, Power Supply noise from the PI is somewhat reduced when the jumpier is removed.
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.
