I hooked up my speakers (Studio 20's L/R, CC690 Center, ADP590's surround, and a Sub15). Then I hooked up my Pan BD65 BluRay (HDMI).
I installed the ARC software (on a laptop running Windows 7). That went smoothly. I hooked up the ARC Mic using the supplied USB mini-standard cable and put it in the supplied tripod. This struck me as to why Anthem is spending money to supply a tripod, but they do.
The first glitch came when the instructions said to hook up the serial cable to the Anthem (that part was easy) and the other end of the cable to the laptop (that part really shocked me). Why? Because the other end was SERIAL. Even the software says you must be using Windows XP, Vista or 7 - so who has a laptop/computer with a serial connector. So I called my dealer and he actually had a 'Serial to USB' to lend me, so I picked it up and hooked everything up.
I put the mic in position 1 and started the ARC software. The first thing I noticed was unlike the Denon's and Yamaha's I've used in the past, the frequency sweep tone sounded different. It sounds like a digital version of someone saying "Worst". It took about 12 minutes to do all the testing for the five positions. Then it took an agonizing 15 minutes to update the MRX-700 with the data (I think that's why Serial ports are dead).
The one area I'm confused by is setting the MRX-700 to use the ARC settings. I went into the setup and under one of the AUDIO options (I forget which one) it said "ARC" and 'YES' was selected. Normally I'd assume it was setup properly, but the ARC Software manual says you can use both a Movie and a Music setting depending on your source (I'd imagine for CD you'd use Music and for BluRay Movie), but I couldn't find this option. At this point (9pm at night) I wasn't going to bug my dealer, so I'll ask him after I'm done with work tonight- but if anyone has an answer before that, I'd appreciate it.
While the ARC graphs show improvement, I was surprised with a noticeable drop off over 10KHz in all the speakers. The blue line (which shows the optimal Freq. Resp.) was flat from 20-20,000, but the calculated measurement (the green line) showed a significant drop. Any ideas from people who have used ARC before?
I may have left some stuff out in the setup process, but I'm happy to answer any questions.
