If you're an owner of a recent vintage Onkyo receiver, you may have the received the wrong microphone for use with its Audyssey calibration system. I bought the 707 in 2009 and learned this weekend that perhaps a year's worth of units were shipped with the wrong microphone, min included. Onkyo has recently said they will replace the shipped mics with the correct models. The shipped microphone is model no ACM1. The correct model is ACM1H. The model is on the original packing box the microphone came in. The easiest way to submit a request is through Onkyo's website. I've read you can call or email, too. http://www.us.onkyo.com/feedback_form.cfm (And FYI: your unit's serial # is on the original packing box, so you don't have to waste an hour trying to squint at it on the receiver in the dusty, shadowy back of your entertainment center.) I submitted my request Sunday night and today received a confirmation from Onkyo I don't personally know how many units this affects in Onkyo's line. Audyssey is encouraging people to do this as well. I suppose they don't want their good name damaged by Onkyo's hardware goof. I've read this makes a big difference in how the Audyssey software works. (Mods, please forgive me...) Details can be found at AVS in the Onkyo 707 thread http://www.avsforum.com/avs-vb/showthread.php?p=19885737&posted=1#post19885737 and Audyssey thread http://www.avsforum.com/avs-vb/showthread.php?p=19877679#post19877679
Looks like much ado about nothing. From the Audyssey Rep who initially encouraged folks to request a new mic: http://www.avsforum.com/avs-vb/showpost.php?p=19908199&postcount=35568
Wondering why I have two setup mics, and which is the correct one I google ... And find my own thread from two years ago
I was working for the wholesale distributor at the time. We actually had some 706 still in the box, So a couple were opened up, and sure enough...the box of the 707 and box for the 706 "said the same thing"...but the mics were indeed different. Installers were the ones most embarrassed by this...then. It was one thing to buy it from Best Buy/Amazon and have this come up, it was another "I'm going to build you the HT of your dreams" person get kicked in the nads.
