It will have stereo RCA in and out, and 1/8" mini in and out. All it will do is attenuate 2.5khz by 3 dB, with a Q wide enough to modestly affect frequencies from 1kHz up to 4kHz. Essentially to mildly scoop out those audio frequencies humans most readily hear. One could plug a line source or phone into it, and RCA out, IE, to a stereo amp. One could use the built- in tone controls('Bass', 'Treble'), to tailor the ends of the bandwidth to taste. Result? A smoother, less intrusive sound at background or concert- hall levels. What materials do I need? You want a parametric EQ you can build yourself. Good luck with that. Gareth. |

No use pointing me at a set of Fletcher-Munson curves. I met those more than 60 years ago so if you think they're a point of enlightenment for me. Wrong. Particularly wrong because those curves are statistical averages for particular known levels. If you're trying to produce a response contour, those curves are not *it*. Turn up the volume a bit and your ears will respond differently. If you're trying to attenuate the mid-range audible levels for yourself, then you're intensifying the effect. Possibly wrong. If you think that a source has not had sufficient attention by the recording engineer at the time and that he/she did not endeavour to ensure a good result (one which you don't like) so you alter the response that's for you to decide. The easiest way is to build *nothing* and just raise the trevble and bass controls a fraction - same result. |

I have looked and asked at several drug stores for the 99% but none had it. Finally ordered some off Amazone for 3 pintes for about $ 15. Postage would make it more, but needed soe other things so got free shipping. YOu might look for some of the things that look similar to qtips but have a sponge type of tip on them in the makeup section. I usually use some of the Kemwipes that leave almost no fibers . You may want to try some of the cleaning tissues for glasses that have alcohol already on them if this is just a one time thing. |

I usually get it at Fry's, in the electronic-tools section. Online... Amazon or eBay would probably work. >I'd also like to find something that won't leave lint like a qtip has. There are foam-tipped swabs (look a bit like Q tips on steroids) designed for just that purpose. >I had no idea CD books are done with a less expensive method similar to >home burned. These days, burning is used for a lot of smaller CD production runs. I haven't priced things lately but I suspect it's more economical for any single-run batches of less than a thousand copies. |

As my wife likes certain Yuban Gold coffee that is not in the local stores any more, I ordered lots of that and the 99% for the free shipping. It seems to be 99% as I put equal ammounts of that and some Walmart 90% in some open containers (about half a teaspoon) and kept checking on it. The 90% still had something left in it after all the 99% was gone or almost gone. |

Actually, NTSC color makes pretty good use of bandwidth when you're constrained to all-analog, vacuum-tube technology. When it was introduced, compatible color was right at the cutting edge of (or maybe a bit beyond) technical feasibility for commercial (not to say consumer) electronics. Isaac |
