  1. Outputs When the Helix XLR outputs are subjected to phantom power, the output level is decreased. Do not try and connect your Helix to a mixer, interface, or PA system that supplies phantom power (48v) to the Helix XLR outputs. The workaround is to use the 1/4" outputs instead. If your setup requires XLR usage and phantom power cannot be avoided, we've seen some customers have success with a phantom power suppressor. Input When using the XLR input with a microphone, do not "hot swap" the cable. Do not have the 48v phantom power engaged when plugging in an XLR cable. It's best practice to plug in the cable with a mic attached to the other end, then go into Global Settings>Ins/Outs and turn on the Mic Phantom Power. Make sure to disengage the 48v before unplugging the cable as well.
  2. I am getting nasty electric shocks from guitar to microphone with my X3 Live. I have a much loved Pod X3 Live - and I have recently discovered (in our new practice room setup) that I get shocks when holding guitar and a properly grounded microphone. I have troubleshooted the system and mains supply thoroughly, and traced this to the way the X3 Live processes incoming phantom power. I have excluded bad grounds on all devices, except the Line 6 POD X3 which has no independent ground via its (original) Line 6 power supply - (ie the ground is 'floating' as it should). The negative power supply connection is not ground. I bought a new digital multi-meter to troubleshoot this. I though it was a mic signal path problem at first but have now ruled that out. I've measured 48-50V between the guitar and any good ground, eg the vocal mike in our studio /rehearsal setup - and other guitars, rack kit chassis etc. Though just 50V, it's still a noticeable shock, a lip on the microphone was the first experience and is quite a 'belt' very much felt with fingers too. The voltage drops to zero when I turn off the (global) phantom power on mixer My signal path is: Guitar > Pod X3 > XLR out L to Desk (for monitoring) and XLR out R straigh into to a Firewire 8/8 Recording interface. If I have phantom on on either of those, there is 48-50V potential between the guitar ground and a microphone. Turn both off, no voltage present. The conclusion I have come to is that there is a problem in the Line 6 Pod X3 Live unit that's causing the phantom potential to raise the guitar input's ground wire to become 50V above ground 'proper'. As our desk is Phantom Power 'global' (and other devices like active DI boxes and condensers need the phantom), it's not something I can turn off except perhaps by buying a decoupling transformer as a phantom blocker. I've tested adding a ground wire from my guitar to another guitar (other ground) - to check that the mixer phantom power supply does not object to that by just sending the unwanted 50V to ground - and remaining phantom-powered items connected to the board are still operating OK. They do. So I'm thinking to jury-rig a 'proper' ground to the Pod X3 Live unit somehow to defeat this issue. I'm minded to make a cable that connects one end to a good ground- the mains socket - and then using only the green earth wire of course, and connect this ground to the X3 Live to an used connection (XLR Microphone input Pin 1 ) which my meter tells me is on the same ground buss as the guitar input (as it should be). I am well out of warranty with Line 6 on this unit, while Line 6 have been very helpful to me with an issue I had once before (on my Variax 300) - I'm not expecting their help on this or for this to become a 'send back for repair issue', and am not sure if it's a problem that has always been present and I have just noticed it... My question to the forum community is: has anyone else experienced anything like this? Perhaps in the X3 schematics there is something that shows the circuit schematic of how phantom power coming into the X3 Live through the Direct Outs as is in my case, on pins 2&3 is raising the ground voltage of the guitar input to 50V above 'good' ground. Perhaps there is an internal component that has failed. If so, what would it be? Is there an internal decouplng transformer to disregard any incoming phantom voltage that has failed? Thanks for your time reading this.
  3. Hello Line 6 Community. Been using Line 6 products for more than 10 years now, but always for live sound. I just started my home studio and decided to go simple first, so I already had a Line 6 TonePort UX1 and I decided to use it as my soundcard/table. I play guitar and always used my toneport with programs like gearbox, guitar rig and amplitube. It always worked well, but I've never tried XLR input of my toneport since I never wanted to record voice. Then I bought a mic. Without knowing what "phantom power" and "condenser" mics really meant, I fell for a Behringer B-1 mic. For in case you guys don't know, it's a XLR condenser mic (which needs 48v power to work). So I turned it on my toneport and the expected happened: "No sound". Then I searched in the internet for the cause and it led me to "Phantom Power boxes". I bought one of these little boxes that apparently have a XLR input, a XLR output and a Phantom Power switch. I rigged everything to my toneport. When the phantom power switch of the box is off, the green light saying 12v appears. In that case, the microphone works but with a very low audio gain. Ridiculously low, srsly. When I turn the Phantom Power on, the red led says 48v and then... for my surprise... it doesn't work at all. The toneport doesn't get any sound. Then I thought that it makes sense, "How does the toneport will receive a 48v signal by being only connected in a USB input?". I guess the guy who said to buy a phantom power box thought that the toneport ux1 was connected to another source of energy, not only USB. My question is: Do I have to upgrade to Toneport UX2 or other newer version which doesn't rely only in usb as a power source so I can use my 48V mic? Or it should have worked 48v in my toneport? I'm lost now, since the internet says one thing and I've tried and didn't get results... Thanks in advance and have a nice day, guys.
  4. Recently got my Line 6 m20D and I have been working my way through all of the amazing features I read about in the great stories of the fabled product descriptions and videos (sorry I am watching Lord of the Rings while I am writing this), and I was wondering If anybody knew the more technical details behind the 48V phantom system. Do you think there would be some possibility of a firmware update which would allow for individual 48V signals to be sent to each channel?? I know for me it would be excellent to have the ability to individually select a channel for power so I dont have to loose a row to those pesky power hungry condensor's. Then my other question pertains to the direct to USB, are there any drivers needed to make this feature work. Or should I just be trying with something a bit more powerful than Audacity. When I was messing around with the direct record to computer I had not yet installed my copy of Ableton (I should preface I am on windows 8.1), and so I was wondering if there were drivers I was missing, or anything in particular I haven't read about. I look forward to learning more and more about this system as it grows into the amazing beast it is destined to be (again sorry Lord of the Rings), and thank you Line 6 for these forums! They are super awesome and helpful!
  5. Phantom power is DC (or direct current) used to power certain microphones, the UX2 and KB37 offer 48-Volt signal to a condenser microphone by connecting it to the XLR input on the unit. The UX1 does not have phantom power, if you have a microphone that requires such power you will need to get either a standalone microphone preamplifier or one that is built into an audio mixer's input channel. Also available are stand alone phantom power boxes. (A good example of this device is the Rolls PB23 Phantom Power Supply). Phantom power is not harmful to mics that don't need it. If a mic does not need phantom power it will ignore the 48-Volts being sent the the microphone. Even with the Phantom Power on, your UX2 or KB37 can have both a mic that requires Phantom Power and a mic that does not require Phantom Power.
