Dumb question about adding a microphone to a receiver's input?

[a-dogg]

I have an Onkyo TX-SR602 and a Pioneer VSX-530-K. I have an event coming up that needs a PA system. Can I buy a cheap microphone and plug it into one of these, add some cheap speakers and use it as a jury-rigged PA?

I have a little phono pre-amp I can attach between the mic and amp, if that helps?

A receiver is something completely different from a pa.... Whether it is sufficient depends on the size of the event

Yes, I get that. It's a very small event, I'm not worried about sufficiency. I just want to know if this will work.

Email the manufacturer, I'm not actually sure how/if this will work. Might need a mic preamp to control input sensitivity.

I have this phono pre-amp, as well as a line-in bluetooth dongle that plugs into my receiver. What if I connected the bluetooth dongle to the pre-amp to an input on my receiver. Then bought a bluetooth mic. Do you think that would work?

The phono preamp will be no help. You need a small microphone mixer to plug the mic into, and then you can connect the mixer to a line in on your receiver.

Most mics are low impedance balanced and that is best. Avoid high impedance mics.

The phono preamp won't work because it has an equalization curve (it changes the signal from the cartridge in a non linear manner) and a fixed output according to standard specifications as I remember.

You need a Mic Pre-Amp and connect it into one of those receivers. Like TLS Guy said a small mixer (like a Behringer) would work.

Another way would be to get a Bluetooth Mic and connect it to the bluetooth dongle (which I assume is a bluetooth receiver dongle - please advise). Seems to be a ton of Karaoke Mics out there that should work.

Something like this: https://www.amazon.com/Wireless-Microphone-Amicool-Bluetooth-Smartphone/dp/B06XFWKXFF/ref=sr_1_2_sspa?ie=UTF8&qid=1505285727&sr=8-2-spons&keywords=bluetooth+microphone&psc=1

Or you can get a wireless Mic like found here for $40.
