How would you connect a preamp that only has an XLR output to an
interface that doesn't have any line level XLR inputs? Would you buy a XLR to TRS cable? Would that distort the sound a bit? For example, if you have an Avalon 737SP and a Digi 002 rack, what would you do to connect the Avalon to the Digi 002? I have a Presonus Eureka right now with an Audiophile 2496 soundcard. The soundcard has S/PDIF connectors but I would need to buy an ADAT card for the Presonus to connect it like that. Right now I use a little adapter that goes into the TRS output in the the Eureka and gives me an RCA connection and I put the RCA cable into my soundcard recording the sound in mono. I'm thinking about moving to the Protools world and need some help on how I would connect it, and is Windows XP recommended, or should I just stick with my nice little Adobe Audition setup. So the real question is, should I just buy a card for my Eureka and hook it up with the S/PDIF in my soundcard? Or should I try going into the Protools world? Or should I just leave everything alone and use the rca cables with my Eureka as I'm doing now? Oh, and how do you get sound from a preamp that has only XLR out to an interface that has only 1/4" inputs? Thanks. |

You would use an XLR female to 1/4"-TRS male cable. There is no signal loss, distortion, or anything. It's just a difference in connection connection.

If the interface has TRS jacks, yes. Would that distort the sound a bit? No, not if the interface has TRS jacks. If it has only TS (unbalanced jacks) then, depending on the preamp's design, you may want to rig up a special cable. Peace, Paul |

After researching it in the IEEE archives, I discovered that when going
from XLR balanced to an unbalanced input, there is actually no accepted standard as to whether or not pin 3 of the XLR (cold lead) should be grounded to the shield. With some equipment, such a balanced-to-unbalanced line won't work if pin 3 is grounded, and with other equipment it will. Same with NOT grounding pin 3: will work with some equipment but not others. You need to try it both ways. |

In othe words,
Pin 1 of the XLR = ground/shield Pin 2 of the XLR = hot (+ve) (to tip of TR plug) Pin 3 of the XLR = cold (-ve) (to sleeve of TR plug) MAYBE connect pin 3 of XLR to pin 1 |

Hassan, there is no one standard method for connecting a balanced
output to an unbalanced input, and given the diversity of the circuitry that exists, there can be no one standard method that is safe and gives the best result in all cases. You must take into account the type of output circuit in the source component. It's best to read and follow the instructions in the manual, and wire accordingly. |

wrote in message ups.com How would you connect a preamp that only has an XLR output to an interface that doesn't have any line level XLR inputs? My preference would be to get an adaptor cable. Connector adaptors would be my second choice because they can put more mechanical strain on the connectors. Would you buy a XLR to TRS cable? Been there, done that although I usually made said cable up myself. Would that distort the sound a bit? Not in the least! For example, if you have an Avalon 737SP and a Digi 002 rack, what would you do to connect the Avalon to the Digi 002? A cable that was long enough and had the right connectors. ;-) I have a Presonus Eureka right now with an Audiophile 2496 soundcard. The soundcard has S/PDIF connectors but I would need to buy an ADAT card for the Presonus to connect it like that. Right now I use a little adapter that goes into the TRS output in the the Eureka and gives me an RCA connection and I put the RCA cable into my soundcard recording the sound in mono. This could be about as good as it gets. I'm thinking about moving to the Protools world and need some help on how I would connect it, and is Windows XP recommended, or should I just stick with my nice little Adobe Audition setup. I'm fine with Audition. Certainly, there are no sound quality issues with it. So the real question is, should I just buy a card for my Eureka and hook it up with the S/PDIF in my soundcard? Or should I try going into the Protools world? Or should I just leave everything alone and use the rca cables with my Eureka as I'm doing now? Unless you've got some problems with audible hum and noise, what you have could be about as good as it gets. Oh, and how do you get sound from a preamp that has only XLR out to an interface that has only 1/4" inputs? Usually, getting a cable with the right connectors on each end does the job. ;-) There's a standard reference that shows the best way to handle all sorts of situations like this, which can be found at http://www.rane.com/note110.html .. It's on the conservative side, which I think is exactly right. IOW, there are sleezier alternatives that might work as well as what they say, but then again maybe not in every circumstance. I think a little common sense goes a long ways with questions like this. If you hook things together you generally get: (1) Good sound (2) Less sound than you expected, but still its all good. (3) No sound at all. (4) Sound with audible hum and/or noise. (5) Really badly distorted sound. (6) Something is subtly wrong with the sound. Item one is the usual case. Item 2 is disappointing, but its one of those things you can get used to. Items 3-5 are pretty obvious and beg to be dealt with. Item 6 is pretty rare. |

Would you buy a XLR to TRS cable? Would that distort the sound a bit? The 1/4" TRS tp XLR (both male and female) are about the most common cables in my room. No distortion that wasn't already there.

Right now I use a little adapter that goes into the TRS output in the the Eureka and gives me an RCA connection and I put the RCA cable into my soundcard recording the sound in mono. The PreSonus option card for Eureka is sync and SPDIF, not ADAT. Since the 2496 accepts SPDIF that would work. But I doubt you would hear any (noticable) improvement over the converters in the 2496. The shortcoming of the 2496 is not it's sound quality, it's that it lacks balanced I/O. The Eureka has both 1/4" and XLR outs. Since it's reasonable to assume that someone might use a 'guitar' cord coming out of the unit, the 1/4" was designed to allow both balanced or unbalanced connection. You can get a decent quality 1/4" (TS) to RCA cable and avoid any adapters. You can also use the insert send on the preamp and bypass some of the circuitry you may not be using. I'm thinking about moving to the Protools world and need some help on how I would connect it, and is Windows XP recommended, or should I just stick with my nice little Adobe Audition setup.

Or should I just leave everything alone and use the rca cables with my Eureka as I'm doing now? Changing software will not solve any hardware issues or vice-versa. Audition has some advantages over PT. Have you upgraded to 1.5 ? Just get a good 1/4" to RCA cable and eliminate the adapter, and you are set with what you have. Oh, and how do you get sound from a preamp that has only XLR out to an interface that has only 1/4" inputs? You can never have enough cables and adapters. good luck rd |

Thanks, I think I'll just get a new cable so the adapter is out of the
way and stick with this setup. I like the sound, but people using the expensive stuff usually intimidate me a little...that's why I keep having 2nd thoughts about upgrading the whole setup. I haven't heard an Avalon 737SP / Digi002 combination that sounds worst than my setup...but I have heard better...not a lot better...but better. But then again, I guess spending multiple grands just to improve the sound a little is not worth it. Thanks people. |

By the way, here's a little sample of my sound right now:
http://www.unparagoned.net/snippet.mp3 Would love to get some feedback. It's 256kbps mp3...shouldn't be too bad. |
