I’ve been looking for a version of this with 2.1 for a passive subwoofer with bookshelf speakers. Everything I’ve seen is only two channels.
Unless maybe I set the sub as a second airplay or Bluetooth device and run one of these [1]? I’m not really sure how all of that works.

- currency 4y ago2.1 systems generally use powered subs, not passive subs. For use with higher-quality bookshelf speakers, you can send the stereo line level signal to a 2-channel amp and pass the high-level speaker lines through your sub. I do this with Belkin AirPlay 2 receivers and it works well. Not all subs have high-level passthrough though.
- dmix 4y agoI'm building my own subwoofer, so I'm assuming you mean the sub has a plate amplifier in the back? Like this: https://www.daytonaudio.com/product/776/sa70-70w-subwoofer-plate-amplifier https://www.daytonaudio.com/product/776/sa70-70w-subwoofer-p...
- currency 4y agoYes, exactly. And that plate amp has the passthrough I mentioned, which not all plate amps do.
