There is also a form of it that is inherent in vinyl LP's. On tape, it may depend on storage time or tape type. Resistance to "print through" can be obtained by means of tape formulation. When listening to LPs. it may take some detective work for figure out whether the pre or post echo came from the master tape used to cut the LP, or the LP itself. On the LP it is a consistent 0.555 sec echo, while on analog tape the timing of the echo depends on the speed of the tape which may typically be 15 or 30 ips, and the diameter of the tape pack that the media comes from which is constantly varying. This means that tapes that are auto-reversed or played in both directions such as 4 track tapes have different echo timings depending on which way the tape is winding. Pro tapes are typically recorded only one way. Echos on LPs can be avoided by using a coarser pitch during the cutting phase, which may also decrease playing time per side. Careful pro workers rewound the tape which often made the echo weaker or even lost it in the hiss. ------------------------------------------------------------------------ arnyk's Profile: http://forums.slimdevices.com/member.php?userid=64365 View this thread: http://forums.slimdevices.com/showthread.php?t=106519 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/audiophiles
