Unleash Full Audio I/O with the 8xIN+8xOUT for Raspberry Pi 5!
Take your Raspberry Pi 5 audio projects to the next level with the 8xIN+8xOUT, the all-in-one audio interface designed for ultimate flexibility. Building upon the success of our popular 8xOUT, this new HAT adds eight high-quality analog input channels, transforming your Raspberry Pi 5 into a powerful audio processing and streaming hub.
Whether you’re building sophisticated multi-zone audio systems, immersive home theaters, experimenting with spatial audio, designing custom active crossovers, or capturing multi-channel recordings, the 8xIN+8xOUT provides the comprehensive I/O you need. Simply plug it onto your Pi 5, enjoy automatic driver installation, and start streaming and capturing high-resolution audio across a total of sixteen channels!
Designed exclusively for Raspberry Pi 5.
