Location: Netherlands | Hi!
I'm the proud owner of an Adamas 2008 collectors (#63) and I have a little question about the VIP5 preamp. Should the XLR out of the guitar be capable of feeding the preamp though phantom power?
Used together with the dummy plug it works fine, but I once have had the preamp powered up via XLR only, but after some time plugged in the signal dropped out, and it now only works when I use dummy plug.
Perhaps it's just not designed for running on +48v power. Like to know!
Regards,
Robert |

| Welcome to the board, Robert. I too have an 08C (#21), and this is my first experience with the VIP. There was a recent thread stating that you need an XLR cable with a grounded pin 1. That may be your issue. If you can't find one in the Netherlands, contact either Paul Templeman in the UK (thru this board, do a member search), or Al Pepiak at http://lostartvintage.com in the USA. They might be able to help you out. |

Location: East Wenatchee, WA | Older XLR do not have the #1 pin grounded. I have found several newer microphone XLR cables that work just fine whereas my older ones do not.
HOWEVER: The Phantom power WILL NOT power the VIP. The grounded pin only provides the means to activate the switch that turns on the pre-amp, but the VIP runs ONLY on the battery.
I have verified this at every level, by pulling my batter, using a dead battery and including confirmation from the pre-amp manufacturer.
I have both a 2080 and 2008C with the VIP.
Hope this helps. |

I'm sorry, but I don't understand why they would bother to include such a feature as you describe, it makes no sense. Either the preamp operates on phantom, or it doesn't, and having phantom PSU power a switch but not the unit would be total nonsense. As I understood it the VIP will operate on phantom with an XLR which has a pin-1 short to ground. If you are correct then they should withdraw the VIP and have it redesigned.
The processing in the VIP is very power hungry. Why would they make it dependant on a limited-life 9v cell rather than a constant 48V supply? I'm not doubting your personal experience, it just seems very strange. Anyone else? |

I went beyond personal experience on this one. |

| This is a good information quest, I am sure there are many who have not posted who would like to know. If antone gets an answer from the factory please post it.
I have a couple of guitars coming and I too would like to know if I will need to buy a bigger stack of batteries than normal. I love my earlier electronics. I am sure they are slightly behind the times soundwise but man the batteries last and last. And this is good as I always forget to replace them. |

Location: Keller, TX | At the Factory tour in 2006, this was described as a design "feature".
At the Factory tour in 2007, they admitted it was a design "flaw" that was caught too late in the production process to change.
I sold my 2007 KOA a while back, but did alot of testing on it. This is what I remember:
Yes, the VIP does run off phantom power. Yes, you need a cable with pin 1 to ground connectivity. Yes, you have to insert a dummy plug or cable into the 1/4 inch port to activate the preamp. However, once activated with the 1/4 inch plug, it draws power from the phantom source, not the battery. |

Location: East Wenatchee, WA | OK....so if I get this straight,
Plug in properly grounded XLR, plug in dummy plug and viola, I am running off of phantom?
So if I turn off my phantom power at the mixer I should lose power to my pre-amp right (as a test)?
I will try it out if that is the case. I don't think it hurts anything to turn off the phantom while plugged in right? |

So....how can we actually test this? |

| Now I have to ask a question, I'd say a Stupid Question but actually it is pretty good. I am the one who's stupid. Here it goes......
How can I know the difference between these cords? Grounded pin or not?? does one have a different number of pins??
Also does the Studio version of the new onboard electronics have this feature/flaw as well? |

Location: Netherlands | thanks for the many replies already.
I sent an email to adamasguitars already but didn't get an answer yet. I'll send the same so ovationguitars, perhaps it'll be answered more quickly.
Testing if the vip pre will run on phantom with the dummy plug inserted indeed seems to be a little difficult.
I tried a bunch of xlr cables but they're all quite new, so I'm quite sure they will all have ground/shield connected to pin 1. (@ northcountry, it's about the wiring of the shield/hot/cold inside the mic cable to the 3 pins of the XLR connector, so you can't see it from outside) |

Location: Chehalis, Washington | Robert, try to contact either John Budny or Kim Keller...they should be able to answer your question.
I had a 2080 for a bit with the VIP, and from what I could tell, the preamp does run on phantom ONLY IF you have the grounded XLR plug (thanks again DVD for that one) and a closed plug in the 1/4" jack. I did find out that an open ended plug (such as a 1/4" to 2mm headphone converter) does not work as a "dummy" plug. You actually need the plug that Ovation produces, or a regular 1/4" cable plugged in and hanging loose. (Why this works is anyone's guess)
Trouble is, doing a true test is difficult, since the VIP will not run in ANY mode without a functional battery in it.
All things considered, I love my Pro-Studio, and will always consider the Optima my favorite preamp. |

The Studio does NOT have this "feature". Just plug in and go. |

| I guess I will be OK, I will have Al set me up but I was just asking because I do not carry a meter around to the music stores, and I hoped there might be a simple or obvious difference that I, or any of the other members, could see right away.
Interesting problem. |

"The VIP preamp does not run on phantom power. "
Quite a pity... |

Location: south east Michigan | The VIP does have it's quirks but I really like the sound it provides.
I'll have one someday. By that time the VIP-2 might be out and it will address some of these concerns. |

Quite a pity... I agree. This is the response I got after putzing with the VIP for almost six months last year and talking via email with John during that time. I really want a Phantom powered unit and that is the only negative of the 2008C that I can see. But...I live with it by buying gross lots of 9v batteries at Costco and just keeping one handy. You do not have very long after the light blinks before power is gone either. I do the "tongue test" before playing on Sundays just to be sure that the battery has power, and I unplug the guitar when it is just sitting (i.e. during announcements and such) to preserve power.
Besides licking a 9v battery reminds you that you are still alive. :eek: |

Hopefully the VIP-2 will: (1) operate the tuner without a dummy plug; (2) pushing the tuner button will activate the tuner long enough to tune 6 (that's right 6) strings instead of 3; and (3) run on phantom power. |

Location: SoCal | Nothing in the Ovation preamp should be this complicated. You want a preamp in a guitar with which, you can just plug in and go. A preamp with this many quirks should simply be junked, written off, and never used again. I wonder how many people, besides those on this board, bought a guitar with one of these preamps, tried it, couldn't figure it out, and junked the whole guitar while at the same time, badmouthing it to their friends? |

Location: Omaha, NE | I'm not an expert by any means on phantom power, but I've always assumed it was designed for extremely low amperage situations. Electrically, condenser mic's are pretty much just capacitors. As such, they draw virtually no power through a phantom power supply.
The VIP is totally different. Its got significant power needs to drive all the internal IC chips. My assumption is that there are limits to how much power you can draw through a phantom power supply, and the VIP would exceed that (but in a quick Google search I couldn't find any specs saying precisely what the max power would be).
My experience is that the VIP is more power hungry than my Optima, but not exceptionally so. If the low battery light starts flashing during a show, I've got no worries at all about making it to the next break before replacing it.
The big battery killer for me is forgetting to remove the dummy plug. I guess that's why they call it the dummy plug. |
