Therefore, when using dbx Type I noise reduction, it is *imperative* that the same exact piece of equipment used to encode the recording is used to decode the recording, otherwise funky things can happen in the final product. Obviously, the person who decoded the Betty reels did not have access to the same board used for the encoding. In this case, the voltage mismatch has resulted in the bass frequencies being boosted by about 10 db, but there has *not* been a similar boosting of the treble frequencies. So, when you receive these tapes and play them back, you'll have to turn down the bass response knob on your stereos in order to get a playback that sounds right (don't turn up the treble response knob). If you do that, the true beauty of this recording will jump out at you. If you don't, it's gonna sound kind of muddy and deficient in the high end. (BTW, this is true for *all* of the Betty Board tapes that were dbx Type I encoded/decoded).Art Link: http://www.gdcdcovers.com/annex.html gd1977-05-08.jpg gd1977-05-08-1.jpg gd1977-05-08-2.jpg gd1977-05-08-3.jpg
