Hi Andrew,
Great fundamentals covered in this series so far. I'm looking forward the the tweaks and fine tuning that is anticipated from the rest of the series.
I have a question on placement of rear surround speakers in the 7.1 channel configuration. Is there a minimum distance that you recommend from the rear surround speakers to the ears of those in the seating row closest to them? And how would you setup the system volumes for each? For example, if I place two rows of seating in my theater, I will be using either automatic or manual "room correction" (hopefully Dirac from an XMC-1) to set levels for each channel. I guess the minimum distance really relates to some minimum sound level from the rear surrounds to "satisfy" the 7.1 listening experience criteria. But I think that minimum speaker distance is how this would be achieved. Also, in the setup process, I expect that I will optimize levels for the primary seating location(s) in the front row. That means that the rear channels will be playing at a louder level in the rear seats than in the front seats. I don't see a good way around this potential level imbalance, other than compromising the levels for both rows of seats by placing the microphone used in the level-setting process between the two rows, and I don't think I want to go there.
Thanks in advance for your (and others') opinions/experience on this setup question.
Cheers!
Chuck

At 1.40, what's an Emotiva Fusion 8100?
Looks suspiciously like a Sherbourn SR8100 rebadged?
Cheers
Gary

I watched all four videos. Excellent job, Andrew! The material is presented in a relaxed format and doesn't come across as overly technical (a boon for newborn audio enthusiasts). Oh, did anybody else spend more time gazing at the XMC-1 than at Andrew in the first video? And the second? Third?   Now that I think about it, Andrew could have picked one of the gorgeous gals from Emotiva to host the show, and most of us would still be ogling that XMC-1.  |

Cheers Gary Hopefully just a prototype since the left and right speaker terminals are on the wrong side. All the wires are going to have to cross over each other. Kind of like the UMC200 and the pre outs being backwards, which is obvious by watching video 3. Great videos though. |

These videos would be great if they were in About.com. I think if someone is buying a product from Emotiva, they would already have head knowledge about hooking up surround sound.

You would be surprised. A large group of customers we have are fresh into this hobby and we are proud of the fact that they decided to start with our products. We are happy to help anyone who needs a guiding hand in getting the best sound possible from their Emotiva gear or just setting up their gear properly. |

Thank you Andrew,
I enjoyed the series so far. I would say you have set the table and now I'm waiting to see what you're serving. A little color in the shirt would brighten up the videos but I do enjoy their quality.
Two days ago my wife and I became the proud parents of a UMC-200. I replaced a dying Carver CT-17. Step 1: Disconnect and remove old equipment. Vacuum out the shelves and dust off the gear. In retrospect I wish I had cleaned up and put on a shirt with some color in it before continuing on. My wife was pretty impressed I could get through Step 2: Hook up the UMC-200. I sprung for the BTM-1. Is there any harm in letting the dongle dangle when not in use or should I toss it in a drawer between uses? I'm now on Step 3: Working on the surround system. My main speakers are Fried transmission line kits I built twenty years ago. It consists of a pair of C/5 Satellites and O/4 Subwoofers. My surround speakers are homebuilt transmission line towers with MTM arranged Focal drivers. The CT-17 had a setting for a Phantom mode that allowed it to function without a center channel. It had five channels but no .1 or independent subwoofer. I have recently replaced the drivers in the C/5's and am very pleased. The O/4's work ok but they could use new drivers. Any ideas on a replacement for the Carbonneau 10" CG-258R drivers? I now have four of the five channels hooked up. They are powered by a Phillips AV-1002, six, 50 W per channel, power amp. Two pairs are bridged for the front and the surrounds get the remaining two. I have an old Rotel two channel integrated amp and a pair of loudspeakers. Can I run the left and right rear surround outputs of the of the UMC-200 into the Rotel integrated amp or must they be connected directly to a dedicated power amp? Is their a Phantom mode on the UMC-200 or is the center channel mandatory? What specifications should the center speaker meet? Do you know of any good transmission line plans for a center speaker in case I choose to build one? For that matter how about plans for the subwoofor? I love woodworking.

So glad to hear you're liking the videos. There are more coming as well as videos relating to specific products etc. As for your question(s). 1) The Bluetooth dongle can remain connected when not in use so don't sweat it. So long as you don't hit it or rest anything on it, it will be fine. 2) Unfortunately I cannot suggest an alternate driver solution for your DIY speaker build. Maybe another user can step in and help you with that as I wouldn't know where to begin when it comes to raw driver parts. 3) If your Rotel has some sort of bypass of its preamp section that allows it to be used as an amplifier then you should be able to connect it (your Rotel) to the UMC-200 the same you would an amplifier. BUT CONSULT YOUR ROTEL MANUAL BEFORE PROCEEDING to double check. If you cannot bypass the Rotel's preamp section then you will not be able to use it as a stereo amp. AGAIN, CHECK YOUR ROTEL MANUAL.  4) If you set the UMC-200's center speaker configuration to "None" then the center channel info will automatically be split between your left and right main speakers thus effectively creating a "phantom center". 5) I'm sorry I cannot be of assistance with regards to DIY center or subwoofer solutions. Thanks for your questions and for watching! Enjoy!!! |

#3) There should be no reason why using that stereo amp wouldn't work to power the surround speakers. Just be aware the volume control on that amp will effect the surround levels. So you'll have to fine a comfortable level to set the volume and leave it in that position. Adjust the output level of the test tones in your 200 for the surround channels either internally in the 200 or by adjusting the volume control on that amp, then don't change the amp's level after you've got them matched in level to the rest of the speakers.

Thank you Andrew and moovtune.
I'm traveling down memory lane as I recall purchasing my Rotel RA-413 shortly after our nation's bicentennial. It was my first amp and it served me well till I sprung for the Carver CT-17. I have high expectations as to the longevity of my UMC-200. Every time I buy an amp it's to replace something branded as "vintage". The RA-413 is vintage-vintage. Somewhere on my 65 acre spread I'm pretty sure I still have the manual but I'm not able to lay my hands on it. Back in the days of Gutenberg and Quadraphonics, menus were only available at the local diner. They were not a part of the audio amplifier experience. Everything was controlled by a connection or a switch. There is no pre-amp disable switch or connection on the RA-413. As a teacher, it was easier to afford the Carver twenty years ago than it was the UMC-200 now. Don't get me wrong, the UMC-200 is more amp than the CT-17. It was much cheaper as well. I'm sure I'm not the only one suffering from the cost of living. Thank you Emotiva for pricing the UMC-200 below $500. I will need to save a while before purchasing any more speakers. It's nice to know I can get some surround experience with only four speakers. I like having a versatile amp that will allow for equipment upgrades like speakers. In the mean time I'd like to see what I can do with equipment I currently have which brings me back thirty five years. I'm inclined to agree with moovtune. I believe a pre-amp to integrated amp connection is possible without damaging either piece of equipment. I'm certain I would not get the ultimate in fidelity but I would think it would be enough to help me decide if I want to go from 5.1 to 7.1. I'm also certain that without a center channel I will miss out on a significant effect but it will do in a pinch. It seems to me that adding one would be my best improvement followed by the subwoofer then additional surrounds. As I progress, 4.0 - 5.0 - 5.1 - 7.2, I think my best source would be a speaker blog. Thanks again.
