Question about Yamaha YBA-11, Bluetooth Audio Receiver, aptX

Yamaha YBA-11 needs a USB connection for the power supply and a coaxial input (digital input) for the signal at the amplifier. If I have researched correctly, the PianoCraft E410 has neither. so the answer to your question is: No, cannot be used on a PianoCraft E410.
The USB port could be provided by an external USB power adapter, but the PianoCraft E410 lacks the more useful part, the coaxial/digital input.

I also need the coaxial input on my Yamaha A-S701 amplifier.
Works without any problems. Whether the part can also be used for a Pianocraft, I don't know.

Hello, it needs a coaxial input socket, on my YAMAHA receiver RX-V467 this is under AV2. Works very well and at a relatively long distance. I'm not an expert, that's all I can say, I'm 100% satisfied. SB
