I have a friend who had his Crowson set up with the analog output from his Oppo. He recently added a media server to his system which required him to move the signal source from the Oppo to the subwoofer output of his pre/pro. He is a less happy with the system configured that way than with the signal coming "unaltered" from the Oppo. Part of that is because it is now controlled by the Master Volume Control and he needs to be more concerned about turning the MVC up and down. Part of it is also the alteration of the signal by Audyssey.
If you can figure out how to do that, please post it.
I am the friend Craig is talking about. I have an OPPO 83. Yea, I know it's old
. I first experienced the Crowson system at Craig's house. After 5 min I was hooked and I wanted to find a way to do with my system. Lucky for me Craig had a spare Transducer. So, I bought that from him and I bought the Butt Kicker BKA-1000 amp. When I first got it I was wondering how we would connect everything. Craig said the best way was with the OPPO outputs. This is done for two reasons. First, the Crowson does not need any correction by an EQ. Second, You will be able to control the overall level independently from the master volume. Both of those things made sense so that's what I did. I absolutely love what it does for my system. But, I also started to want ease of use for my system. So. I started looking into servers. I ended up buying one that is already made from a company so I did no have to build anything myself. So the good part is ease of use and everything at my finger tips. The bad thing was that I would now have to connect the Crowson and Butt Kicker up to the my Integra itself. That means that it will increase and decrease in intensity as I go up and down with the overall level. I should mention that I am extra sensitive to blowing out a Crowson because that already happened to me.
When I got my Butt Kicker amp(which was the same model that Craig used when we tested it in my room) I just put it to the same level on the Butt Kicker as before and played a movie at my normal level. Well, I fried the Crowson because the overall gain of the newer amp is greater then the gain that he had on his amp. I just want to make clear at this point that the Crowson was fried because I had the gain on the Butt Kicker too high NOT the over all level of the my Integra. At that point, they were still separate from each othe
r So when I got the Crowson back I lowered the gain and raised it slowly until it was where I wanted it. It worked great. Then, I decided on the server. I learned that the Crowson would now be "connected" to the MV. Not only that, but I had to raise the level on the Butt Kicker because it was not as strong connected to the sub connection on my Integra as it was on the OPPO. So, we fiddled around and got it to the right level. Now, I still get a great tactile feel when I watch movies, but it is probably not as strong as before and I still have to be careful with the overall level because I don't want to burn it out again. My room is small so I can get away with having my system played at a lower level. If I were in a bigger room, I might be concerned.
So now, I am using the server as my main source and I just have to be careful how loud I put the overall level. But I still wish I could separate them somehow just to make me feel more at ease. Like I said, I don't put it that loud in my room. Normally between -18db and -16db. I know that is really not loud at all, relatively speaking, but it's loud enough to just be fun in my room and I can still feel the Crowson's doing their thing. But here is the thing, I am friends with someone else on the forum. His handle is BrolicBeast. He has a killer system and he is using a server as well for his primary playback. He also has an OPPO 105. In addition, partly because of me, he bought a Crowson system. He loves it. But I was wondering how he had it setup. I told him not to crank the amp powering the Crowson based on my past experience. I was curious how he had it connected though so he did not have to worry about raising tjhe level of the Crowson as he raised his overall level. This is what he said.
"Oh no--I have my media sever connected to my Oppo BDP-105's HDMI inputs so I can control the levels separately from the 8801's MVC. It's a unique option available only to Oppo 100 series and Cambridge Audio Azur 752 owners though. I found a standard setting that keeps things very natural and tactile, so I keep the Crowsons at the one setting at all times, except for gaming--I turn it up two notches on the iNuke amp for gaming for an unbelievable experience. My standard listening volume for movies and music is -5db (I have my processor programmed to always remain at -5db at startup, regardless of what the volume was when I turned it off).”
So that allows him, somehow, of keeping the two levels separate. He can keep the Crowson at a certain level but put the MV as loud as he wants and it seems like he doesn't have to worry about blowing up the Crowson. Now, it works for him but to be honest, I don't understand it %100 and if I am wrong in my analysis, I welcome any corrections. So, that may have bypassed the level issue, but I am guessing the Audyssey issue still remains. I will say for me, in my small room, with my limitations, the benefits out weigh the negatives with having a server and the Crowson setup like I do. I have watched a number of films that way, and even though it may not be exactly like before, I have come to be happy with the results.
P.S Sorry this went so long and I hope what I said is accurate and made sense.Edited by MIkeDuke - 7/10/13 at 10:14am
