STS frequency range

STS frequency range

2001-04-21 by Sebastian Kuehnl

Any data.. or vague suspicions on frequency rolloff throughout the STS
system?
PCO & NTO deliver up to 100 KHz, but which of the audio mixers/ VCAs/
processors/ ringmod/ FRS/ WAD (tightest VC BBD delay I know of), or even
dividers/ (Schmitt) comparators/ BLOG, can handle this (how much can they)?
The VCFQ and VCFS had 16 KHz top in the 80s, same with STS? VCF2 highpass
section limits (audio spectrum limitation would make less sense in a
variable bandwidth filter to me)?

Thanks for any hints,
Sebastian

Well, a few of the catalog entries mention module specs but as a whole
Rex doesn't really blow his horn on this one... it would be interesting
to put a Serge on a pile of high end audio test gear.

Rex did mention that he was able to drive an NTO with a 30 vdc control
voltage to > 1mhz... waveforms were pretty distorted at that range.

His choice of silver solder, silver mica cap's and other examples of
audio overkill would lead me to believe that most of the modules would
have very good bandwidth.

The filters of course would have some kind of bandwidth limit.

Rolls-Royce used to have a policy of not publishing engine
horsepower/torque specs on their car engines... instead saying that it
was adequate. It seems like Rex is saying his specs are adequate also.
