This is a very common problem. I had the exact same issue. Follow Bob's directions and you'll fix the problem. Just to add a couple of notes, you can also call your cable company and have them come over and fix the ground problem. The way I solved mine was by using a Panamax power conditioner/protector. It had coaxial cable input/output. I just routed my cable line through it and all the hum went away.

I had the same problem with my cable box. I installed a Jensen Transformers VRD-1FF ISO-MAX Cable TV Ground Isolator between the wall jack and the box and the problem went away. You can buy it from several on-line retailers. Runs about $55.00-$60.00. There are cheaper ground isolators out there, but they may not have the bandwith necessary to carry all of your high def stations. Cheaper ones did not work with my Time Warner cable box.

Please understand that while these ground/hum blockers do work, they are not the "best" solution. The fact that there's garbage to block means the grounding of the Cable TV feed wire is not functioning properly. That grounding not only drains off the garbage causing the noise, it also protects against surges coming into the house on that feed wire's shield.

So it is always best to START by trying to fix the grounding of the Cable TV feed where it enters your house. If you can't completely eliminate the problem that way, then look to a ground/hum blocker gizmo.

If that still doesn't fix it, then there are cheap gizmos called ground/hum blockers that you can insert in-line on the feed wire coming out the wall. Basically these are little, cylindrical transformers that do not connect the shield from one side to the other. The cable signal passes through the transformer, but any garbage coming in on the cable shield can't get to the other side. Because these are cheap and because cable signals cover a pretty wide range of frequencies, you may find that inserting one of these means you lose signal strength on some channels. So try to fix this by correcting the feed wire grounding first. (NOTE: You can't use these for satellite feed wires because there are DC voltages on satellite wires, which they block, that are used for sending control signals to the satellite dish.)

I am glad I found this forum. All of you are extremely knowledgeable ! Thanks. I think I am going to start by calling Comcast. I really don't want to do anything that might degrade the signal.

This is my first blue player and my first real high end piece of gear. It sounds great , and makes video look great! I plan on upgrading speakers and Amp within the next 6 months. I finally connected the 105 to my wireless router today. It indexed all the wave files on my computer.................. and wireless streaming sounds pretty darn good! Compared to my Jolida JD100 CD player, the Oppo seems to be more detailed for sure. The Jolida's bass is a little heavier , but the bass with the Oppo seems tighter. Sorry for the ramble.. This is fun. Back to listening...........

I had the same issue and Comcast sent a tech out to look at it. He found that the cable ground at the house had been installed improperly. Someone had put a piece of copper wire a couple inches into the dirt. They ran a new 12 gauge ground wire from the cable splitter directly to the ground in my main panel and all the ground loop issues went away. No charge.

Great suggestion Kal!

 

An other one cancel your cable TV that's what I did 12 years ago it works great :)

I have not been able to get my 105 detect a usb thumb drive that I have my music files on from my Samsung Galaxy S2 phone. The music is stored on a 32g sd card and I use an adapter to make the sd card function as a usb drive. It is FAT32 compatible and my computer reads it ok but not the Oppo. I get a message from the 105 say "not supported." The Oppo will detect a regular usb thumb drive. Maybe micro sd cards are not supported. Thanks for any input.

I've had my 105 for about a week now and noticed that when I press the Open button on the player it powers the unit off. The open button on the remote functions properly. Anyone else have this issue?

Obviously that's wrong. biggrin.gif. Haven't seen a report like that here.

Give OPPO Tech Support a call. They may ask you to do a firmware re-install and reset of the player, but more likely they'll swap it out so they can see how it failed.

The way I was thinking of setting up the system I proposed above would require the 105 to have to have 3 separate analog outputs.
I realize that Front RT, Front LT on the surround sound can be set to down mix into stereo.

This leaves the 2 Stereo Balanced & Unbalanced analog outs. Is this a choice on the remote & on the remote app? I need to be able to "toggle" between these 2 & do not want each to be active simultaneously.

Seeking to have 3 separate 2 channel Zones & open to suggestions.

I have 3 zones setup. So that can be done. Of course it is only "one" Blu-ray player, so all zones set to the Oppo hear/see the same thing from the Oppo - if I want them to. I am using a PrePro to manage the source/zone audio matrix. The Oppo facilitates this by having a stereo Downmix output, but it doesn't have any idea about the zones.

I am using the app regularly. On iOS it needs to reconnect each time you switch between another app. It functions well and fast although the volume button is not helpfull to quickly move the volume up or down. As part of their tweaks I hope they introduce a slider for volume control.
No macros either so the 3 zone controll is going to be a tricky one. And it will not output different signals to different outputs. Seems u r back to basics. It can be the single source but all controls you need to have in the zone itself.
Overall I use the app for ad hoc control. For regular use the physical remote is simply faster and usable with your eyes on the screen.

Has anyone experienced the volume control set on fixed being too "hot" going into the preamp or amp? I ran the oppo XLR outs on fixed into a Cary Audio SLP 03 tube preamp into a Bryston 14bst amp. It seems that there is clipping going into the amp causing premature clipping into my new Salk SS8 speakers. Looks like by moving to variable and reducing the level I can get more headroom and stop clipping. Does this make sense?

All outputs are always active and the volume control on the player affects all the analog outputs the same, so there's no way to get independent volume control for the various analog outputs. How were you planning to address volume control in the 3 zones? That would presumably give you a way to mute the output on the zones you don't want active at any given time. It sounds like what you really want / need is a multi-zone AVR / pre-pro or a multi zone audio distribution system which would be better equipped to handle your needs.

Sure. It's a bit unusual for a pre-amp to not have enough input headroom, but if you hear better audio via Analog by lowering the Analog output Volume a bit then you should definitely do so. Fixed Volume is equivalent to Volume 100. Each step reduction in Volume is -0.5dB.

If you are using positive values for your Analog speaker volume trims, try lowering all your trims by the same amount instead so they are all 0 or negative values.

The XLR outs are the standard +6dB hotter than the RCA outs. Your pre-amp may have an input sensitivity adjustment you need to set when using XLR.

You could runn the Oppo directly to 3 separate amplifiers with speakers for each of the "zones", all you would need to do is power on and off as you require the zones to be active.

If you want each "zone" active at the same time with volume control for each of them individually, it is not possible without a pre-amp to switch between the "zones". .

Each "Zone" would utilize it's own Digital input, zone 1= coax, zone 2=optical , zone 3= USB. Easy enough.
6 channels of amplification is not a problem. How to keep all 3 zones from playing simultaneously without a visit to the equipment closet is escaping me.

A really nice 2 channel with an Aton DLA4 could be a possibility? While this would have the ability to play all zones at once, which people always claim they must have, it has been my experience that in real life it rarely happens. Now let me tell you the story of pulling up to a hungover buddies residence one Saturday morning to hear the hilarity of a porn soundtrack being broadcast from his outdoor speakers to the 16th green @ 10:00am.

Certainly hope a later app update has a volume slider!

In my case I had time Warner come out and check all the lines, including the ground at the main box. I live in a cluster development and one main cable box feeds more than one home. My other setup in the living room is more basic and does not have the problem. Agree that the block may not be the best solution, but it was the most cost effective and took care of the hum.

I was just wondering whether the signal-to-noise principle applies to the analog outputs of the Oppo? If you are pushing the output to the maximum of 100 is there any degradation in S/N? I was surprised that the fixed output would be the maximum.

Most multi-zone amps / distributions centers / AVRs have the ability to mute the zone or power down the zone amplifiers. And there's usually not a need to feed each zone with a different Oppo output - I'm mult'ing the stereo outs to feed two stereo audio zones and that works fine.

Stevepow,
You are feeding 2 Zones from a single analog output from the 105, correct? Tell me more. what am I not understanding? I could easily play his 6 channels at once like this, but control of what zones are on via Ipad is my end goal.

Sorry for duplicate post.

Actually highest volume without clipping (or distortion) yields the highest signal to noise ratio. There should be no clipping at volume 100 unless you have turned up the gain in individual channels during the speaker set-up phase to get all speakers at the same level.

Yes, I am splitting the analog out with a couple of RCA y-cables - I couldn't detect any degradation in sound quality - the sound of those stereo outs are so good, splitting them was the best result for me. As for zone control - many amps and processors have iPad/iPhone apps - or have a browser interface that allows for power on/off and volume changes - both my Denon and Marantz AVRs and PrePros allow for this. It's nice when sitting outside on the deck to be able to control the music with my phone.

Search for universal remote for iPad and you'll find quite a few apps out there that can control all sorts of equipment.
