Make sure you are running the most current App 2.60.2 and the current firmware for the amp. I believe it's 2.61

Looks like some people are having success with iOS11. Doesn't appear Apple has issued it for iPhone yet.

The same thing happened when Apple went to iOS 10. Guess Line 6 is not with the program....AGAIN! I set my iPad to not update unless I do so manually. In other words I shut off automatic updates. Did the same with my phone.

Never mind I figured it out dah! Unistalled and reinstalled the app fixed

I updated the iOS software on my iPad and now all my tones are missing and when I select a song from my song list to jam along with the app doesn't load ant tones. I believe this happened before but I don't remember how I fixed it. Help!

No apologies necessary Mark. I believed you meant headphone jack. I run mine through my home stereo surround system and at times I plug in one of my amps to go along with the audio on the stereo. I also have a Line 6 FBV Shortboard Mk II that I use with it. I haven't figured out all the nuances of the Shortboard yet but will be working with that this next year. Merry Christmas!

Microphone port? There are two "mains out" on the back of the unit (left & right). Two RCA connections to go to a home theater surround system. One "Amp Out" to go to the "guitar" input on the amp, however, only the guitars output will be present here. To get audio from another source such as iPhone/iPad/Andriod device you must route the output (mains or rca) to monitors or home stereo. You can also patch from the "Amp out" to the input on your amp (typically guitar input) to run your guitar through the amp while playing the audio from a source via the AMPLIFi app, but again only your guitar will be present at the amp. I hope this helps and isn't too confusing. There is no "microphone port" on the AMPLIFi TT. There's is a USB port and an Optical port on the rear. The USB port is for updating the firmware on the unit and the Optical out can be routed to a stereo amp that has that capability.

Exactly. The Amplii TT has a very low output. You need to connect it to either a Home theater sound system via RCA (red & white connectors) or to a Powered PA system in order to have stored music audio present (i.e. To jam along with). You can connect it to an Amp via "Amp out" however, only your guitar audio will be present. Any music played from an iPad, iPhone, or Android will not be heard.

I ran the update for iOS 9.3.1 on my iPhone 5C and it wouldn't connect via Bluetooth at all. I tried about 6 times ....no go. I haven't ran the update on my iPad and I won't until I know for sure the update works. The update my iPad wants to download & install is 9.3 not 9.3.1 but I still won't do it. My iPad connects immediately but like I said I haven't ran the update on it. I'm running the Amplifii TT.

Is the Amplifii TT connected only to your surround sound system via RCA connectors? It would seem it is, you can play music from a source (i.e. iPad, iPhone, Android) I'm not sure what you mean by "surround sound", I imagine you mean your home theater stereo system. The Amplifii TT has a very low output so you need to turn your surround sound stereo up because it uses the power amp section of your stereo system to add power, but here again you are able to play music so it would appear you have that done. Also, if you connect an amp via "amp out" on the rear, your guitar sound will be routed to your guitar amp and you will not hear it through your stereo system, only the music will be fed through your stereo. The only other thing to do is open a trouble ticket with Line 6. This Forum is not for troubleshooting.

Has anyone updated their devices i.e iPhone, iPad with this new update just released by Apple? Any problems?

You need to get a "Line 6 Shortboard Mk II". It connects to the back of the TT via a cat 5 cable, included with the Shortboard MkII. It allows you to access the many banks of tones & also there are 4 user programmable slots where you can assign your own tones to those locations. I believe you can also overwrite tones in the other many banks, not too sure of that since I haven't tried it. It allows remote control via foot switches. My wife got me one for my birthday last Sept.

You need to make sure there are no other devices operating in the Bluetooth range of 2.4ghz. Items like other cell phones, iPads, etc.....anything that could possibly cause interference with the Bluetooth connectivity. Even other items like a laptop, Bluetooth headset, etc will cause problems. The AMPLIFii TT can only accept ONE device via Bluetooth. Next make sure the "FLASH" update has been made to the AMPLIFii TT which I believe is now 2.50.2 and the APP is 2.50. Also, I'm not sure how your updating these devices, (Windows computer, etc) but you have to use the correct download/update utility to "FLASH" the AMPLIFii TT. Meaning if you using Window 8.1 then use that utility, if Windows 10.X then use that utility, otherwise I believe the update will fail. Beyond that you would have to contact "TECH SUPPORT from LINE 6" possibly via a "trouble ticket". Hope this helps some. I know how frustrating it can be.

Line 6 makes an "FBV Shortboard MkII that interfaces with the AMPLIFii TT. It connects to the back of the AMPFLIFii TT via a CAT 5 cable that comes with the FBV Shortboard MkII, which then allows you to select tones/effects and also to store downloaded tones to the FBV Shortboard MkII. I have not tried taking the output of a pedal board as an input into the AMPLIFii TT.

I have an iPhone 5C and just downloaded the update to iOS 9.2 and I've seen no problems. I have the AMPLIFi TT.
