Dear all, I have just the same plan (playing in nursing homes). Playing is singing to a half-playback.
I do have some on an android tablet that have been made like a karaoke version (CD+G), where the lyrics scrool along in sync. No crap but made with Biab and a DAW.
I use the headphone jack to feed my small mixer that takes my mic on a second channel. The mixer employs an effect processor (mainly reverb and compression for my voice). The mixer feeds my power PA (amp build in).
This works well, at least in my garage.

I could use bluetooth to connect Tablet to mixer, but I preffer the cable. Having read all this good advice to avoid the tiny headphone connector, I started thinking about some interface that would use the usb connector of the tablet and provide more stable jacks on the other side.
Does such a device exist? Would the small usb jack be more reliable than the headphone jack? And wouldn't such interface add complexity and another point of failure?
What is your take?
