Location: Battle Creek, MI | Ok....so i finally finished my project of removing my old preamp and replacing with Optima with the XLR out. Honestly, I dont really care that much about the XLR out, but it was part of the circut board so i drilled it all out and installed it. Can anyone tell me if there is any difference in sound between the 1/4 our and the XLR out. Volume doesnt really count because it would have higher gain at the board. I just wonder if anyone can really tell any difference. |

Location: closely held secret | I don't know if it's measurable by the human ear (certainly not by mine anymore) but the XLR should be 'quieter' noise-wise. I believe it's due to the lower signal, but Temp could explain why better than I could.
There shouldn't be any difference in the true tone of the sound, unless you're picking up so much noise in the 1/4" that it's actually distorting the signal going to the amp.
Arlene, you get 10 points for courage!! |

it probably has something to do with the low impedance signal.
all les pauls guitars had lo z pickups he thought they were higher fidelity |

Location: Scotland | High-frequency response should be better, as a low-impedance balanced line doesn't act like a treble-bleed capacitor in the way that a regular 2 conductor guitar cord can when it's dealing with a high-impedance signal (whether your sound system and/or ears are good enough to percieve that difference is another thing) And as the Wabbit said, running a balanced line gets rid of noise (RF or mains-borne interference for instance) Other than that there should not be much of a difference, tonally.
That said, I always run balanced, though never with the onboard XLR, but that's just because of the peculiaritities my current live setup. I use short cords from the guitars to a DI box then to the board. Amounts to the same thing as using the onboard XLR |

Location: Battle Creek, MI | Hey thanks for the responses. Thanks to Al again for sending me the optima preamp. When I figure out how to upload photos, I will post some pics of the final installation.....I was a challenge for sure, but I got lots of help from this board and the template for the XLR was very helpful. |

Location: Battle Creek, MI | Thanks.....I had to buy a step dril for the larger hole so that was about 25 bucks...but all in all...it came out really nice......but it helps to have the people here on the site giving information and advice......it takes very careful measureing and remeasuring....I found that the hardest part was getting the holes just right for the anchor screws........but it worded and its sort of fun having the XLR....the old S771 never saw it coming |

Location: Battle Creek, MI | Thanks! The XLR template that i downloaded off the board was the most help. That and using a step drill to make the hole. Its just and older S771 but it is a sweet playing guitar and the new install has made it just that much better. |

Daniel I guess you could use an XLR to jack but it's pointless and defeats the whole object of the XLR output, as you'll be trying to send a low-impedance balanced signal into a high-impedance unbalanced input. Plus you can't supply phantom power to the pre using that kind of cable. |

Location: Battle Creek, MI | That is a S771....here is a pic of the optima ..I replaced the OP24+ as I wanted an onboard chromatic. I added a pickguard and it really changed the overall look...Its a nice playing guitar and the Optima is great.  |
