Jan Myren asks about using DBX to playback 78s .
Here is my take on this : DBX Noise reduction is an encode in recording
and decode in playback system designed to reduce tape noise in
professional recording studios . There was an attempt by DBX to interest the record
industry in a version designed to be used in the mastering of 45s and lps and
the decode unit was to be incorporated
into the preamp or the playback system . The company I was working for at
the time , Nashville Record Productions in Music City USA was given an
onsite demo of this system and it was considered by many
in the industry for adoption as it was quite effective.
The big drawback to the DBX record system and the reason for its'
lack of acceptance was that the DBX encoded record was most unpleasant to
listen to on a playback system that did not have the DBX
decoder ; making compatibility in the market place a big problem
So; DBX for playing 78s is a not a good idea . Even recoding a 78 on tape
with DBX encoding , and playing the tape back through the DBX in decode
mode will only reduce the tape noise and leave the record noise
untouched . I tried this in the '70s ! BTW : The DBX record noise system
had radically different characteristics from the tape noise reduction DBX
system . The artifacts of tape noise are quite different from those
of record noise .
78 playback is best done ( IMO ) with the proper choice of stylus to
match the groove , using a mono cartridge or a stereo cartidge wired
for lateral only and then possible cleaning up the transfer with some
tastefull computer based noise reduction such as Sonic No Noise .
Just my 2 cents , hope this info is helpful !
