How to connect a wireless microphone receiver to a portable speaker aux input
Hi. I'm a bit clueless when it comes to audio connections, so forgive me.
I have a wireless microphone receiver for exercise instructions. It has an XLR balanced output, and a 1/4 inch jack unbalanced output. I think the outputs are mono since there is only one actual physical microphone.
I have a bluetooth rechargeable speaker, with an "aux" 3.5mm stero input.
I would like to use the speaker with the receiver.
I tried a guitar lead with a 1/4inch to 3.5mm mono converter. A multimeter showed electrical connectivity to be fine for these to. But there is no signal at all from the speaker.
I also have a twin 1.4 inch jack to single 3.5mm stero jack audio cable. If I connect one of the 1/4 inch jacks to the receiver, I do get microphone audio from the speaker. But this leaves the other 1/4 inch jack unconnected, so it's noisy. Plus, I suspect I am only driving one of the speaker's stereo channels this way.
What's the simplest way to connect the two? I'm not sure if I need a pre-amp or not. The manual for the receiver says it has an audio output of 150mv. I do have a powered "Sideman SM-3 Parametric Equalizer" unit I could use. I'm not sure if it is a pre-amp, but it does seem to give a lot of signal boost.
Thanks for any advice.

You need a 1/4" jack to 3.5mm stereo jack lead.
The tip of the 1/4" jack must be wired to both the tip and the ring of the 3.5mm jack.

You will only need to use a pre-amp if the the portable speaker aux input is not adequately driven by the 150mV output of your receiver.
If you got sufficient loudness when using the twin 1/4" jack arrangement, you should be good to go using the lead I recommended.
It would be nice to know the input sensitivity of the aux input, if you have access to the portable speaker manual.
