So this will make it so this same exact thread is shown there? Yes. The same posts will appear in both groups. This only recommended when the subject is on-topic for both ( or more ) groups. Ok, how can I do that? Ohhh - possibly since you're using google groups you may not be able to ! Do you have an ISP with a news server ? Such as news.myisp.com ? If so - use a proper newsreader - or even - dare I say it even Outlost Express. I use the newsgroups function in Netscape. I happen to like its format. Google groups is a truly dreadful way to access Usenet. Graham |

ups.com... Thanks, I wasn't aware of this. I remember getting something like this with my Pendulum Preamp. Either the preamp is already designed for this or this little adapter does the trick. So it looks like I'll be able to use the Pendulum and not have to get a DI box. Check it out: http://www.pendulumaudio.com/SPS-1.html Anyway, when I tried the pickup I just went straight into the console. I had given up on the pickup before bringing in my pendulum preamp to use with the mics. Someone asked about the quality of the Pendulum. The quality is amazing. It's my favorite piece I own, more so than any mics or other things I own. My guitar is my baby though. My pickup is a Fishman Rare Earth. It's supposed to sound good. I think I will try it with the Pendulum and see if that does it. I suspect you will be astonished at how good it sounds. I think the one Renbourn was using when I worked with him a couple of weeks ago was a Fishman Rare Earth as well, and it's about as good as I've heard a pickup get. The Pendulum should do a good job of terminating it. I tried using just one mic on the guitar and one for voice yesterday. I also flew the speakers up as far as they would go (6 ft). The brand of the console is Crate Audio. If the speakers are also Crate then that's another part of your problem. Their speakers don't have particularly flat frequency responses, and the peaks add to the feedback problem. Peace, Paul |

It must be a psychoacoustical effect. g There's no technical reason why this should reduce the tendency to feed back, unless there's some very large phase shift associated with the amplifier's input attenuator or mixer's main output fader. Which there won't be of course. I tend to like to run amps with the attenuators down some so you can get a 'hot mix' on the desk. Trying to mix with the led ladders causing clipping when they're only 'half way up' is nonsence. Most modern desks have the classic 0dB ( may be dBu or VU depending on mfr ) mark around the middle of the led ladder in order to accomadate digital headroom. Graham |

Welcome to the real world. If the pay is good, leave your ego in the parking lot and accept the fact that you're acoustic wallpaper. Play songs that you're still learning or practice hot guitar riffs. They'll never notice when you make a mistake. But stay tuned to your audience.

I'll add keep an eye out for good looking women on blind dates with losers or assholes.

Speakers would be the first place to start (as already mentioned taking
them off the ground will make a difference) Also, put them at the end of the room instead of the middle - then people can choose to sit near or not - that way the people who want to chat over their meal can get a seat away from the sound, and not fight with it, and those who want to listen can get close, and will be quieter (in an ideal world - it won't work perfectly,but it will help) Position yourself out of direct throw range of the speakers - ie behind them. From what you say, the music isn't over bassy, which is the frequency most prevalent from behind a PA due to the spherical dispersion. Other frequencies have a more directional dispersion. If you can't do any of that, work out which mic it is that is causing the problem (I would suspect the Shure), by deliberately inducing feedback on one mic only (do it during a break, when the place is full - you don't need to push to full howl round, just to the point it starts to build, and note which mic causes most) If it is the Shure, you could get a directional muffler for it like the ones tv or film engineers use - they usually set you back around =A3100 - =A3250 for a good one. Or tune the room (either spectral analysis if you're a sound gorilla like me, or by ear if you are a good musician). Find the frequencies that cause the feedback (it will usually be one main frequency, with a 1st order harmonic either side) which reacts to the room acoustics badly - I've seen rooms with more, but they tend to be stone barns with lots of fixed furnishing, and odd shapes. Then set up a compressor with side chain eq between your mixer and amp to keep that frequency under control. Remember as well that tube amps actually add a certain amount of distortion (usually lots of 2nd order harmonic which sounds nice - the cause of the "warm" sound tube amp users like), but it is still a form of harmonic distortion, and will induce feedback more readily than a more linear amplification without the distortion. Or you could get a feedback destroyer - which is essentially the above idea, but with several compressors linked each to a parametric eq (Behringer do one that works fairly well. Expect to take a hit on sound quality, but only when necessary). They work well, and have the benefit of an auto listen and tune mode (which much to my suprise also works well) If you're in the UK, I have one of the above Behringers that I'm selling (don't do band work anymore, and it's surplus to requirements - well looked after though, and I have the manuals, and probably the original box somewhere). If you're interested (I'll probably want about =A340ish for it), email me at . We can do it through ebay or something (I'm going to list it anyway, but would be happy not to have to...Shameless selling attempt over, and my apologies to all for the fact that this ng is an info node, and not a marketplace...:-) ) Also, if you want to get in touch at the email above, I am happy to give you a more in depth analysis of the room and setup (we can do it on here, but I'm not very regular in my newsgroup habits, and it will probably take a good few answered questions to nail it fully. I can save the mails, and post them as a faq if there is interest). Feedback is a swine though. I've been in that position often enough that I'll happily help anyone as much as I can (definetly comes under the heading of my boy scout good deed for the day...:-) - the fewer tarnished Karma's from feedback the better - I used to end up apologising to everybody for days after a bad run in with howlround, because it made me really snappy and grumpy until I'd sorted it - usually got lots of noise from the bands too who would spend days rubbing in the fact that it was them who had the right to grump, as it was my job to solve those problems, and having me grump about them wasn't fair...:-) Anyway, hope this helps some.

BTW - with ref to posts on netiquette, can someone tell me how my posts
are coming out on nntp. I'm using google groups to post, as my net connection is slow, and I don't have to d/l on google. I will go back to nntp if the way google posts replies gets up anyone's nose though (get broadband finally next month anyway and I'll go back to using nntp then, but there seem to be some fairly *ahem* strong views on proper netiquette here. Would prefer not to offend anyone between now and 27th july.) Cheers Leo |

Sorry. email address got half deleted. Liking google groups less and
less.... Email is "thealternatives @ gmail.com" take out the spaces before and after the @ obviously. I suspect google are *keeping* me safe from spam or somesuch. Doesn't work of course, as the spammers use the nntp header anyway... Leo |

I couldn't get the pickup working without lots of distortion/static background noise. I tried it with the pendulum preamp. I knew it couldn't be the pendulum so I examined the pickup and reread the instructions. It says if there is distortion you should change the battery. Thing is I've barely used the pickup so I never thought it could be the onboard batteries. This battery is a 3V camera battery or 2 1.5V's stacked. Well, I changed the battery and the Pickup came alive. Lesson: Never trust the onboard battery that came with your gadget. Your sound is only as good as the weakest link... it really rings true right about now. Can't wait to use it now... it's sounding so great now. |

Peace, Paul I tried the pickup through the pendulum preamp yesterday. I had the sm58 and the pickup going through the preamp on the 2 separate channels. I then monitored with headphones plugged into the preamp. When I was listening through the headphones I got a strange buzz. Strangely I could avoid some buzz simply by turning the guitar or swiveling my position/facing. I faced north I got lots of buzz. I faced west no buzz.??? It's too bad I have to face north to present myself to the audience. I moved a little there or a little here I could change the volume and amount of buzz. Any ideas on what could be causing this buzz? It was so distracting I couldn't monitor with headphones in the end. Turning down the pickup gain revealed it was to do with the pickup and not the vocal mic. I don't think it's the headphones because I use them all the time and have never encountered this problem before. I thought maybe the adapter on the end of the jack was providing a bad connection. I will try a different adapter today. I thought also maybe some magnetic fields caused by something in the restaurant ceiling was the culprit. I have no idea what it is. I tried the ground lift switch on the pickup and that did nothing at all. I tried everything I could on the preamp. Oddly enough, I got no buzz at all through the house speakers. Those are also made by Crate Audio by the way. So it's something to do with the preamp, pickup, headphones, and house. That's what I've narrowed it down to so far. |

This is the pickup nature. High-Z unbalanced connections are always sensitive to RF noise issues. Look for nearby noise sources like CRTs, TV sets, light dimmers, touch lamps, and neon signs. Oddly enough, I got no buzz at all through the house speakers. Those are also made by Crate Audio by the way. At the same location or a different location? --scott -- "C'est un Nagra.

I looked around and I can't figure out what is creating it though. There are no cell phones near, there are the speakers of course a few feet in front. I move away from them and the field gets even stronger so I don't think that's it. I can't remember, but I think I turned them off and it was still there. There is an air conditioning system, dimmers in lights above me. If you turn off the lights the field should be gone though, shouldn't it? We turned off the lights and it was still there. I don't know... Perhaps the air conditioning... I think I'll just have to come in early some time and find a new area to play in. I told the owners about a distributed sound system.

I think this should work, it will get the speakers away from the stage at least. I just have to figure out where exactly, and how many speakers they need for a good balance.

I think I'll just have to come in early some time and find a new area to play in. Most likely source is a dimmer someplace, and it doesn't have to be right near you; at Focal Point electric guitars buzz when you face certain directions on stage (one of them being out at the audience). The chief engineer used a cheap guitar for a probe and discovered the culprit was a small, cheap dimmer -- in the restaurant next door. Other possibilities in your case include a utility transformer in the back and a fluorescent light in the kitchen. If it's a buzz rather than a hum, though, first suspect is a dimmer. Hums and buzzes are the curse of magnetic pickups; perhaps a fancier one will have better humbucking coils. Or you may have to rely on orientation to keep the hum down and ambient noise to hide it.

Way better than any website. Peace, Paul |

Either that or go with 1 mic and no pickup. I'll try a few more things next week. |

If you're a customer, I'm a sales clerk, and we're talking over a sale, I would expect that we're close enough so that the hearing aid would work without an induction loop. You seem to have missed the point of recent European disability legislation. It's no longer there to help disabled people in a logical way, it is there to make everyone and every business demonstrate that they are doing *something*, even if that 'something' is completely pointless and may actually make the situation worse. That way, there is plenty of employment for 'trained' civil servants to come around and check that the 'something; has been done. When everyone has finally done whatever was specified, the people who invent and enforce the laws and run the training courses will have nothing to do, so they will invent another raft of idiotic regulations and the costs of being seen to do something will ratchet-up even further. I am all in favour of helping disabled people, but we leap-frogged over the basic and the difficult bits of that many years ago. The whole thing has now become an expensive form-filling exercise. -- ~ Adrian Tuddenham ~ (Remove the ".invalid"s and add ".co.uk" to reply) www.poppyrecords.co.uk |

But what do they send to the loop? Does the clerk pick up a microphone and talk (through the loop) to the customer? Yep the mic is usually either built into the couter or on the back of the portable induction loop An induction loop is designed to work with a hearing aid. If you're a customer, I'm a sales clerk, and we're talking over a sale, I would expect that we're close enough so that the hearing aid would work without an induction loop. Maybe so, but regulations is regulations I can see it where a gas station is unattended outside and the customer needs some help. There's often an intercom for this which is hard enough for those of us with normal hearing to understand, but it's not because of a lack of volume. In a grocery store? Yeah, I guess it's important to hear that grocery store music and announcements of what's on sale (which actually might be of interest, but most people read the flyers). On the counter for the benefit of the hard of hearing, I dont think they deliberately pipe the advertising through it I have nothing against the hearing-challanged, I just think some laws to accommodate those with disabilities are kind of silly. Yep, I can agree with that in some cases. The program material - whether music or speech is usually 'collected' by a microphone, fed into a powerful amplifier which is capable of driving a very low impedance load, and hence into a loop of wire, often all around the building. Theatres often have just a pair of mikes up in the ceiling somewhere. Right. So pull out your guitar in a theater, plug it into an amplifier, and the movie sound track comes out of the speaker. The problem here isn't stray audio (that's another thread), it's a hum or buzz. Unless there's a strong buzz being sent to the induction loop (in which case the people with hearing aids would surely complain) that can't be the problem here. There is often a lot of extranious noise on induction loops, They are generally very high gain systems. It`s probably not the problem in the OP`s case, but still something to be aware of. Believe me, if you're playing something like a Fender Strat or Tele with single coil pickups in a room with an induction loop, you`ll experience anything from buzzing, to uncontrollable feedback. Can you explain why? Maybe feedback if you're feeding the loop with your amplifier. But why buzzing? Yep feedback, guitar picks up it`s own signal but it`s not feedback from the strings, it`s oscillation, the same as when the gain is high on the guitar and the pickups are responding to the field from the speakers. As has been said before most single coil pickup guitars buzz and fizz anyway, picking up the field from their own amplifier, speakers, lights etc. and it`s usually quite directional, Any noise in the induction loop can be introduced into the guitars sensitive pickups quite easily.

They were required to build a wheelchair ramp for it even though it wasn't meant to be walked through by the visitors. That rapidly became a Pargo ramp for the grounds crew who took great sport in driving up the ramp, through the house, and trying to get up enough speed to clear the steps on the other end. -- Hey that's about like a place downtown NEw Orleans where I see a set of steps going into a skywalk system and no possibility of an elevator there. GUess what gets you to the steps? YOu got it, a wheelchair ramp. tHen there's the places where my lady can go in fine, but if she wishes to use the ladies' room independently it's nigh on impossible with her wheelchair. sHE can't open the door and get herself through it, then when she does she can't get to the sink. Then there's a hospital where I volunteer regularly. THe wheelchair accessible buttons are brailled, not the ones on the other end of the elevator. Hmmm, awkward reading braille down near your belt. GUess they figure all blind folks are in wheelchairs grin. Maybe I should sue under ADA because I can't be hired as a truck driver smirk Richard Webb, Electric SPider Productions, New Orleans, La.

GUess they figure all blind folks are in wheelchairs grin. Sometimes when looking for a room on a hotel's web site, I'll check the "senior" rate, and the only rooms they have at that rate are handicap-accessable (the toilet is too high and the shower is too low). And often they're only smoking rooms. I guess they figure all us old folks are in wheelchairs and got there from smoking too much. Hmmm, seen the opposite at motels where I might go, Ramada Inns etc. now and then. Lady needs a wheelchasir accessible shower and high seated commode with the grab bars so she can get her butt off it again. Meanwhile I'm not going to get up and go outside to smoke first thing, especially if they've left me one of those little coffee makers grin. Guess it depends on where you go, hotels and the higher end places think seniors are all smokers and need wheelchair accomodation, drive in motel type places think that wheelchair users will have a carekater who's a nonsmoker.
