Thanks everyone for your replies.
I now have a new microphone and have attached a Super Sound High Impedance Transformer MT-50 and I have sound from the microphone coming through the speakers.
However it needs work on the settings and it would be much appreciated if I could receive some assistance.

Hi Ken,
You don't need to use such a High-impedance Transformer in-between. To connect a standard low-impedance dynamic mic, just use an unbalanced "XLR-female to mono TS plug" cable as mentioned. Make sure the SX900"s Mic/Guitar switch on the rear panel is set to MIC. Then this input set to connect a standard low-impedance mic.
Then use the Mic GAIN knob on the SX900's rear panel to set the Mic Input Gain correctly. Refer to pages 100/101 in SX900 Owner's Manual for this.
Finally make sure the Mic is switched ON in Mic Setting display and set the desired Mic Volume there (depending of course also on the currently set Master Volume).
Please also read the chapter "8 Microphone" from page 93 in SX900 Reference Manual.
Hope this helps!
Best regards,
Chris
