Wanted - Onkyo speaker setup microphone

Bit of a long shot but I'm after a speaker setup mic for an Onkyo TX-NR809

I'm sure the older models 875/876/906 etc are all compatible so if anyone has one or knows where I can get my hands on one would be apprieciated

Thanks for looking

i could lend you mine mate? wouldn't fancy selling it, altho i have never used it
