Beginner - Amp/Mic Advice Needed

Hi There! I am a beginner to amplifiers and I purchased an Aroma AG-15a for busking, which has separate guitar and mic inputs. I purchased a dynamic stage mic (Behringer BA 85a) and an XLR to 1/4inch stereo TRS cord, but there is no sound when plugged in, even with both volume knobs on the amp turn up to full. I tested the dynamic mic on a different guitar amp (no mic input) and it worked, so the mic is not faulty.

I rigged up a connection to the problem amp with a battery powered Zoom H1N recording mic, and it worked, but this is obviously not the mic I want to use for performing. Everything I read says a dynamic mic is plug and play in this situation. I am finding it impossible to find information anywhere about whether there is something wrong with the amp, if I need a different mic, or I'm doing something else wrong.

So having watched a few videos, I discover that I might need a Mic Impedance Transformer to get 'power'/volume to the dynamic mic. Is a Mic Impedance Transformer a type of Mic Pre-amp?

Should I buy a Mic Impedance Transformer or a Mic Pre-amp??

P.S. I made a connection via a Hum Eliminator, and actually heard the mic thru the amp for the first time, but it is still very soft.

How do I solve my problem?

PLEASE HELP!! I'm tearing my hair out!

Thanks in advance for your expertise in this.
