I am currently using a BeoCreate+RPi to run a pair of LXMini speakers. After removing the power reducing pin on the 30W channels this works great. The many filters and shelfs are easily implemented and I love the sleek interface.
My next build is the LX521 speakers, but here I need 10 amplifiers, so even 2 BeoCreate boards is not enough.
My idea is to use 2 Beocreate and supplement these with two additional dsp/amp boards that accept a I2S stream. So each side would have a BeoCreate, supplemented with an extra dsp/amp board running as slave from the BeoCreate.
My question is can I use the BeoCreate as Master and send the I2S from the BeoCreate to another board?
What wires/cables to use? Distance will be less than 10 cm.
