Amplified Output doubt about!

--- Hello friends, I was seeing the topic of Steiner here, talking about increasing the output of the sound card and a doubt arose, <BR> I have a Sound Blaster PCI 16 (128V) and it is quite simple, possesses only a jumper, a position q'' amplified'' and says'' no amplification'' or something like that, since q <BR> bought the card (about 2 years) left in the'' amplified'' .. < BR> I used to have those boxes Creative CS-120 q dao a good little sound amplification and used to own the board, pushing q and q .. <BR> only one year to ca, a computer connected to the stereo Gradient DS-600 with 2 caixonas 8'' with speakers and tweeter, 40-40w RMS <BR> And jumperzinho continues ... <BR>'' amplified'' Sound'' Master'' panel Control is never more than one quarter of the maximum, <BR> never had problems with it but I was wondering oq happen if I change one jumper, and if that way is q (More than 1 year!) run the risk of burning ap . sound! <BR> Thanks guys! <BR> PS :: Once I turned that nameplate msm sound PROFESSIONAL equipment with a mixer, equalizer, Mega 2000Watts Cyclotron Amplifier RMS! (This msm! RMS! 'Is a co q moves with sound! The toy already played a big city nightclub ALONE! Heavy as hell! Over 30kg hehe) With boxes <BR> bitelas a party q I gave here at home <BR> I was in danger of burning it there : Not <BR> jokes: roll: --- <BR> Falouuu thalesbraga <BR> thing is, you can change this jumper w / ñ amp (Line out) yes. I even advise, because you're amplifying a sound twice. All amplifier adds a degree of distortion, and in this case, you will increase the distortion. Another refers to the impedance matching. The amplified output of the sound asks 4ohms pl, p / have as much income as you are putting on an RCA asking 47K ohms and approximately 200mV, you're hurting the quality of reproduction. The fact that you would not be going ds fourth volume does not mean that their sound is powerful, means that you are sending a signal much larger than recommended, pushing and being able to take your sound to burn. The truth is that you can increase the volume almost all the micro with no distortion in sound reproduction. Then control passes to be done by radio. <BR> Make a test, its gradient d eixe low volume, 2 or 3. And increase the volume of micro, notice how the sound is distorted. <BR> --- For my experience, burn your sound card or sound you will not but the distortion will increase .... a lot! (For my ears) ... <BR> The input impedance of the line in the most sound equipment is high enough to prevent major disasters, but due to the imbalance of input and output impedances of the equipment, the distortion is greater ... tb and due to the fact the amp. receiving a signal level higher q it is designed to receive ... <BR> Another: the amplifier amplifies the plate tb the noise. This noise is amplified again by the external amplifier, etc., etc ... in some cases the result is a sound with a background hiss beeem boring! That happens qndo q we install those "boosters 140W Aquarius" in the tape deck and is a ***** sound, wheezing and everything ... it amplifies everything. The sound and the noise along with it! --- You can only burn the Entry or exit! naum or sound card. this is how to plug directly into a mixer down a no entry expecifica! The right the first time on Monday and if you muinto ñ increasing the volume of the Lower until the third time but henceforth only God knows (even though your card is a naum Low: lol: the process is slower)! From fried channel mixer! I speak from experience! <BR> soon change this jumper. <BR> <BR> About distortion .... never try to pass the 80% power at any sound equipment to avoid this inconvenience! if your sound stand today 90% distortion free and you use it 100% tomorrow it will distort at 85% ... continuing so soon will distort your sound by 50%. <BR> (This goes for everyone who gostom to seal the sound: wink:)
