Subwoofer Output Question
(this might be a repost, it never showed up on my ISP's server)
Alright i know that clipping is bad and such, but my subwoofer amp is constantly clipping and not distorting at all. It isn't even enough to trigger the 'warning' light on the woofer. When I put the amp in bridged mode and turn the gain down, the amp doesn't clip but i get distortion and the warning light on the woofer turns on. The only way to reduce this is to turn the gain way down, to levels that are not anywhere near enough or near where it was before the bridge. I've been running it unbridged with the clipping for about 2 weeks, is this bad? Why is it clipping but sounding fine? Why does it not sound fine in bridge mode? Am i damaging the woofer/amp? Here's what i am working withnot great but it was provided with the gig) B-52 Band-Pass Subwooofer rated 550 watts Behringer EP1500, rated 260watts at 8ohms in stereo mode, 800 watts in bridged mono Highs + Mids are on another EP1500 hooked up to Peaveys, but that setup seems to be working fine. As of now there is no crossover, I have the subwooferamp running off of the booth output of my mixer. A behringer crossover(i cant remember the model off the top of my head) has been ordered and should be in this week. I'd estimate that the woofer is pushing 250+ watts in stereo mode, but only about 100 in bridged mono without distorting. Since it is rated 550, how can I get more out of it? thanks in advance -----= Posted via Newsfeeds.Com, Uncensored Usenet News =----- http://www.newsfeeds.com - The #1 Newsgroup Service in the World! -----== Over 100,000 Newsgroups - 19 Different Servers! =----- |

Since it is rated 550, how can I get more out of it? thanks in advance Could you explain how you have determined that the amplifier is clipping? Clipping is a form of distortion. It happens when an amplifier stage is driven up to and beyond the supply voltage (or current if a current amplifier). Imagine that you are feeding an amplifier sine wave and watching the output on an oscilloscope. Well, if all is well you see a sine wave of larger amplitude on the scope. If the amplifier is clipping the tops of the waves will be flattened off because the amplifier cannot supply enough power to form the tops of the peaks; it clips them off. If a light on the amplifier is telling you that it is clipping the you should turn it down until the light goes off. If this isn't loud enough then you should consider getting a more powerful amplifier. A clipping amplifier probably will not damage the speaker, especially if it is not even at a level that you consider loud enough. Really, the only was that you are likely to damage a subwoofer is to drive it too loud and either damage the voice coil by over heating it or by causing the woofer to move in and out too far, again with too much power. I have actually seen a melted voice coil so I know that it can happen. I am a bit concerned that you say that you are not using a crossover. This is not an optional device. I'm not really very familiar with musical instrument equipment but if there is not a crossover built into the woofer then I would suggest not using it until you have one. Woofers are rugged and not as susceptible to being damaged by too high of a frequency as a tweeter is to being driven by too low of one but it sill is not a good idea. |

Clipping involves (as you describe) a squaring off of the wave, or a leading positive and negative DC edge. This WILL cause damage to a loudspeaker in the form of damage to the voicecoil - and it won't take long to manifest itself. For this very reason it is SAFER to overdrive a small loudspeaker with a big amp and keeping the signal clean and non clipped. Those BehMINGER amps are not really man enough and Ive found them quite fun run side by side with the likes of Matrix and Crown. "I can't hear it" being the common comment. So don't trust the rated output. Experience says that if its clipping and it does not sound loud enough then it's just not man enough. |

Being over driven is bad for voice coils. Tweeters oftten fry, in passive x-over systems, when clipping is happening. But, it's not the clipping that's doing the damage. It's simply that the bass clips first, so that excessive gain cranking leads only to an increase in wattage to the tweeters. In an active crossed system, lightly clipping the sub amps is inaudible, and perfectly OK; if you are not, as a result, overdriving your subs.

Subwoofer Output Question
I know its clipping based on the clipping light. I'm familar with what you
said, but it sounds better when its clipping versus not clipping in higher powered mode(bridged mono) at the same sound levels. That doesn't make sense to me, espesically when i came close to blowing the speaker(warning light on the speaker came full on) in bridged mode. The output was no louder than when it is clipping. I know a crossover is needed, I had one ordered as soon as I got the gig. There is one built into the woofer, but im thinking that i might get more power out of the amp with a crossover, since it doesnt have to amplify the highs + mids. That and it will give me more protection for the Peaveys, a guest DJ already blew one. (voice coil burnt) We thought that the other one was blown, but when we went up to look at it, it must have been hit by a basketball or something because the front grill was bent into the cone. Pulled the grill off and it sounded fine. "citronzx" wrote in message link.net... Could you explain how you have determined that the amplifier is clipping? Clipping is a form of distortion.

Pulled the grill off and it sounded fine. "citronzx" wrote in message link.net... Could you explain how you have determined that the amplifier is clipping? Clipping is a form of distortion. It happens when an amplifier stage is driven up to and beyond the supply voltage (or current if a current amplifier). Imagine that you are feeding an amplifier sine wave and watching the output on an oscilloscope. Well, if all is well you see a sine wave of larger amplitude on the scope. If the amplifier is clipping the tops of the waves will be flattened off because the amplifier cannot supply enough power to form the tops of the peaks; it clips them off. If a light on the amplifier is telling you that it is clipping the you should turn it down until the light goes off. If this isn't loud enough then you should consider getting a more powerful amplifier. A clipping amplifier probably will not damage the speaker, especially if it is not even at a level that you consider loud enough. Really, the only was that you are likely to damage a subwoofer is to drive it too loud and either damage the voice coil by over heating it or by causing the woofer to move in and out too far, again with too much power. I have actually seen a melted voice coil so I know that it can happen. I am a bit concerned that you say that you are not using a crossover. This is not an optional device. I'm not really very familiar with musical instrument equipment but if there is not a crossover built into the woofer then I would suggest not using it until you have one. Woofers are rugged and not as susceptible to being damaged by too high of a frequency as a tweeter is to being driven by too low of one but it sill is not a good idea. -----= Posted via Newsfeeds.Com, Uncensored Usenet News =----- http://www.newsfeeds.com - The #1 Newsgroup Service in the World! -----== Over 100,000 Newsgroups - 19 Different Servers! =----- |

Subwoofer Output Question
My problem isn's so much that its not loud enough, but that it sounds like
crap when its not clipping. When it is clipping, it sounds fine. "Lucy Explainin" wrote in message ... "citronzx" wrote in message link.net... "A clipping amplifier probably will not damage the speaker, especially if it is not even at a level that you consider loud enough". Not. Clipping involves (as you describe) a squaring off of the wave, or a leading positive and negative DC edge. This WILL cause damage to a loudspeaker in the form of damage to the voicecoil - and it won't take long to manifest itself. For this very reason it is SAFER to overdrive a small loudspeaker with a big amp and keeping the signal clean and non clipped. Those BehMINGER amps are not really man enough and Ive found them quite fun run side by side with the likes of Matrix and Crown. "I can't hear it" being the common comment. So don't trust the rated output. Experience says that if its clipping and it does not sound loud enough then it's just not man enough. -----= Posted via Newsfeeds.Com, Uncensored Usenet News =----- http://www.newsfeeds.com - The #1 Newsgroup Service in the World! -----== Over 100,000 Newsgroups - 19 Different Servers! =----- |

I'm not sure why you think that a square wave will do damage to a speaker but you are wrong. If you have a signal generator try playing a square wave into a speaker for as long as you like and you will find that it causes no damage. Think about it, what you are saying is that a coil of wire will be damaged by an AC signal if the signal varies in a particular way. This is silly of course as long as the power level is resonable for the speaker. Oh, and I would like to see you graph a signal where a DC signal has any sort of "edge."

Subwoofer Output Question
Behringer are not especially rugged, high end, electronics. They will do the
assigned job. I suspect you'll need an external "Active" crossover inline, just before the amp. That way, you will be able to "Cut" anything above the desired selected hertz you want to amplify and play perhaps 30 hz.- 300hz. depending on your woofers rating. I think your Woofer is trying to play the mid and upper freq's and causing the clip and distortion your talking about. In spite of any crossover that's "Passive" and internal. Are you inputing the signal at the subs LFE? (Low Freq. Extension, RCA connector, usually black or white.) "sk8erteck" wrote in message ... I know its clipping based on the clipping light. I'm familar with what you said, but it sounds better when its clipping versus not clipping in higher powered mode(bridged mono) at the same sound levels. That doesn't make sense to me, espesically when i came close to blowing the speaker(warning light on the speaker came full on) in bridged mode. The output was no louder than when it is clipping. I know a crossover is needed, I had one ordered as soon as I got the gig. There is one built into the woofer, but im thinking that i might get more power out of the amp with a crossover, since it doesnt have to amplify the highs + mids. That and it will give me more protection for the Peaveys, a guest DJ already blew one.

I have actually seen a melted voice coil so I know that it can happen. I am a bit concerned that you say that you are not using a crossover. This is not an optional device. I'm not really very familiar with musical instrument equipment but if there is not a crossover built into the woofer then I would suggest not using it until you have one. Woofers are rugged and not as susceptible to being damaged by too high of a frequency as a tweeter is to being driven by too low of one but it sill is not a good idea. -----= Posted via Newsfeeds.Com, Uncensored Usenet News =----- http://www.newsfeeds.com - The #1 Newsgroup Service in the World! -----== Over 100,000 Newsgroups - 19 Different Servers! =----- |

Subwoofer Output Question
Behringer are not especially rugged, high end, electronics. They will do the
assigned job. I suspect you'll need an external "Active" crossover inline, just before the amp. That way, you will be able to "Cut" anything above the desired selected hertz you want to amplify and play perhaps 30 hz.- 300hz. depending on your woofers rating. I think your Woofer is trying to play the mid and upper freq's and causing the clip and distortion your talking about. In spite of any crossover that's "Passive" and internal. Are you inputing the signal at the subs LFE? (Low Freq. Extension, RCA connector, usually black or white.) "sk8erteck" wrote in message ... I know its clipping based on the clipping light. I'm familar with what you said, but it sounds better when its clipping versus not clipping in higher powered mode(bridged mono) at the same sound levels. That doesn't make sense to me, espesically when i came close to blowing the speaker(warning light on the speaker came full on) in bridged mode. The output was no louder than when it is clipping. I know a crossover is needed, I had one ordered as soon as I got the gig. There is one built into the woofer, but im thinking that i might get more power out of the amp with a crossover, since it doesnt have to amplify the highs + mids. That and it will give me more protection for the Peaveys, a guest DJ already blew one. (voice coil burnt) We thought that the other one was blown, but when we went up to look at it, it must have been hit by a basketball or something because the front grill was bent into the cone. Pulled the grill off and it sounded fine. "citronzx" wrote in message link.net... Could you explain how you have determined that the amplifier is clipping? Clipping is a form of distortion. It happens when an amplifier stage is driven up to and beyond the supply voltage (or current if a current amplifier). Imagine that you are feeding an amplifier sine wave and watching the output on an oscilloscope. Well, if all is well you see a sine wave of larger amplitude on the scope. If the amplifier is clipping the tops of the waves will be flattened off because the amplifier cannot supply enough power to form the tops of the peaks; it clips them off. If a light on the amplifier is telling you that it is clipping the you should turn it down until the light goes off. If this isn't loud enough then you should consider getting a more powerful amplifier.

Clipping involves (as you describe) a squaring off of the wave, or a leading positive and negative DC edge. This WILL cause damage to a loudspeaker in the form of damage to the voicecoil - and it won't take long to manifest itself. For this very reason it is SAFER to overdrive a small loudspeaker with a big amp and keeping the signal clean and non clipped. Oh dear. |
