Burning question that I've never heard anyone say anything intelligent about: I own many cassette tapes, ranging from Cheap type I to exotic type IVs. All of my Type IIs are labeled 70us (where 'u' in us is actually some greek letter whose name I forget. Someone once told me that us is the abbrev. for microseconds...). Most of my type IV tapes are also labeled 70us. My normal tapes, however, are labeled 120us. Also, on the Nak CR2s we have in the music Library, there's a switch for 70us or 120us. What exactly do these numbers represent, what do they do to the sound? Is 70us better than 120 or are type Is 120 to make them sound reasonable? Also, I recently discovered THAT'S brand metal tapes. They are outrageous. They can capture the full sound of a CD, I swear. Dynamic range with Dolby C is a killer 85 Db. Saturation level on long (>1/10 second) sounds is over 8 Db; short sounds like a snare drum can hit 15 Db! These tapes are labeled 3180us/70us. What could this mean? Does it have to do with particle density on the tape? Please resond via private e-mail, since I'm not a regular on this list, and thanks very much in advance!! +=================================================================+ ! I wish you flight, !
