Noise From Marshall TSL's XLR Direct Out
Hello everyone...first post here, and I'm glad this group is here.
I have been experimenting recording, and currently have a M-Audio Fast Track USB, a XLR cable, and a Sennheiser e609 Silver microphone. The mic seems to like volume a lot, and I can't really get my amp loud enough to make my mic happy...level in the M-Audio box is usually near max which picks up a lot of room noise...even "white noise" is well heard in the quiet parts of playing guitar. I tried my Marshall's XLR Direct Out to the M-Audio Fast Track...wow...hey...this thing sounds pretty dang good, IMHO....smooth sounding..I was impressed...a lot. I would perhaps consider this as a main recording line in ( in place of microphones ) if it weren't for one thing: there is audible noise..a "hum" if you will...like a type of 60-cycle noise.....it only goes away it seems when I unplug the XLR from the amp. All tvs are off, no fluorescent bulbs in my apartment...is this perhaps just the noise I hear from my apartment's ( huge NYC building ) electrical wiring? Or is it something inherent in XLR recording? Something wrong or "less-than-pro" construction of the $99 M-Audio Fast Track USB box I got? Could it be my Marshall amp has something wrong w/that circuit? Something else? Anyone else experienced this? Thanks for any replies, Jason |

Put a good mic pre in the equation and you'd be set. Are you close mic'ing? Doesn't seem like it to me.

You are experiencing a 'ground loop' problem. You may be able to fix it by opening up the mic cable and clipping the shield wire *if* your input is transformer isolated. Clip pin1 as well... the balanced signal appears across 2-3. You can do this to a short mic cable and create a 'ground-lift' much cheaper than buying hum eliminator boxes. If you're set up in a bar with cheesy electrics (aren't they all?) one of these can keep your lips from being 'bit'. This is all predicated on the rest of the equipment being earthed, of course. __ Steve .. |

The 609's should have enough output to get above white noise level. The fact that you're getting room noise would indicate that your amp is not turned up far. I'm sure you have the mic close to the speaker, so it's probably that you're trying to keep your neighbors happy but playing at whisper levels. That's considerate, but you probably want to build a small sound-proof enclosure for your amp so you can crank it a bit. I tried my Marshall's XLR Direct Out to the M-Audio Fast Track...wow...hey...this thing sounds pretty dang good, IMHO....smooth sounding..I was impressed...a lot. It should sound better if you mic it.

Could it be my Marshall amp has something wrong w/that circuit? Something else? You're connecting your audio ground to the computer ground. A few different ways for things to go wrong there. Stay with the mic. The iso box will help filter outside noise as well as keeping your neighbors happy. If necessary, get a small speaker cab and build a small iso box around that. Unplug the main speaker, of course. Use a good guitar speaker with same impedance as your cab. Anyone else experienced this? Everyone at some point. |

Yeah..but I was talking about recording at really quiet levels..late at night when the woman is asleep. You are experiencing a 'ground loop' problem. You may be able to fix it by opening up the mic cable and clipping the shield wire *if* your input is transformer isolated. Clip pin1 as well... the balanced signal appears across 2-3. Arrrg! I can't do that...something seems wrong about that..is it safe to do? I mean..I don't know if my input is transformer isolated. You can do this to a short mic cable and create a 'ground-lift' much cheaper than buying hum eliminator boxes.

To r.a.p., you mean If its important to you, yes. I gotta say, Eddie: "First of all, I'm not 100% in love with your tone right now." Still..I appreciate your reply, from here on out: The 609's should have enough output to get above white noise level. The fact that you're getting room noise would indicate that your amp is not turned up far. Exactly...you're right. I'm sure you have the mic close to the speaker, so it's probably that you're trying to keep your neighbors happy but playing at whisper levels. Yup...thats what I was referring to...*really* quiet, so thats why I went direct with the XLR out into my M-Audio Fast Track. That's considerate, but you probably want to build a small sound-proof enclosure for your amp so you can crank it a bit. That would be cool..except I don't have the room for it, nor the patience to build a box, and especially don't wanna take it in and out of the isolation box whenever I waana record or play! It should sound better if you mic it. Yeah...I agree..the mic'd sounds are indeed better in a way, but the direct out does have a certain smoothness that I enjoyed. I think I shall try to blend the direct and mic'd sound like Ron suggested. Thats a very good suggestion, IMHO. You're connecting your audio ground to the computer ground. A few different ways for things to go wrong there. Yeah..I was wondering about that, especially after Ron mentioned that may be a problem if I have it set-up that way..but its the only way to do it with the gear I have for recording so far. Stay with the mic. The iso box will help filter outside noise as well as keeping your neighbors happy. If necessary, get a small speaker cab and build a small iso box around that. Unplug the main speaker, of course. Use a good guitar speaker with same impedance as your cab. Hell...maybe one day I *will* get a seperate isolation box w/speaker in it..I think they are already built for these applications..I forgot where I saw it.... Anyone else experienced this? Everyone at some point. Except those that aren't recording or doing the direct out thingie..right? Peace, ( call me whatever you want here, I guess ). |

So where's the clip Rawk Star? I've been missing in action.
