Location: Colorado Rocky Mountains | I'll be trying out the new VIP electronics during rehearsal tonight and thought I might try the balanced XLR output option. Will I hear any difference? Also, do I need to use the dummy plug in the 1/4 jack while using the XLR option? I think this has previously been covered but I wasn't paying much attention at the time. |

Location: Lake Hiawatha, New Jersey | The XLR output on mine has a much hotter signal than the 1/4 jack, plus it's a balanced signal that you can run directly to a PA without a DI. You do not need the "dummy" plug to use the tuner when the XLR is plugged in. |

As long as you have phantom power from the board AND you are using an XLR cable with pin1 jumped to the shell. Then it works fine. |

Location: Colorado Rocky Mountains | Well, I know there's phantom power coming from the amp, so I'll hook it up and hope for the best. If there is no sound, then I'll use the dummy plug. If that doesn't work, I'll switch to the 1/4" cable, which I know works. |

Location: Sunshine State, Australia | Umm.. Do you need to earth the #1 pin at both ends, or just the guitar end?
If it's just the guitar end, wouldn't it be possible to make that connection inside the guitar, at the jack? Therefore, the cable's earthing configuration would be irrelevant.
Seems simple, but am I missing something? |

Location: SoCal | Not at both ends... if you have to modify your own cable, ONLY jump pin1 to the shell on the guitar-end of the cable.
The XLR swivel-end Planet Waves cables are pin1-to-shell. There were other brands off the shelf that other members mentioned. Check the archives.
Oh... did I mention that if you make your own, ONLY jump pin1 to the shell on the guitar-end of the cable. |

...why not just do a bit of DIY soldering and jump pin 1 to ground inside the guitar?
Wouldn't that negate the need for a special cable? |

Location: SoCal | Murray, The XLR and 1/4 inch are mounted on a circuit board. I looked at a spare for an OP-Pro. The circuit traces are right there. That would be too easy to be the solution. My first thought is that it would put the battery online all the time... just like leaving the guitar plugged in and running down the battery? I'm content with the Planet Waves cable. |

Location: Tampa, FL | For a variety of reasons, you only want a single place where all the grounds are connected (a technique commonly obfuscated by calling it a single point ground). Connecting the two inside the guitar would make this a permanent configuratoin. There may be cases where you want both of your signal wires isolated from the shield. I haven't seen any circuit diagrams of XLR equipped preamps but am somewhat puzzled as to why this particular configuration is necessary. I'm guessing it's because the preamp is sourced from a third party and so complete design control over manufacturing isn't possible. Then again, might just not have occurred to anyone until after the production was completed and so now this is considered a 'design feature' ;)
Barring any other choice, and assuming the the ability to isolate the signal waires from the shield is sometimes necessary, I'd think a switch by the XLR (or in the can) would make more sense.
(Editted cause I can never got something right the first time :rolleyes: ) |
