ARCHIVER Variable Equalization Phonostage

Description
The ARCHIVER is a very flexible phonostage designed to repli ate any known
equalization urve (36 in total), from 78rpm shella s up to the modern era. Cir uitry is
fully balan ed using pre ision mat hed JFET pairs ($100 my ost) for amplifi ation.
Equalization is split-passive, with no feedba k employed anywhere for a more natural
soni presentation. Two inputs allow sele tion between mono and stereo
onfigurations. In addition to the TURNOVER and CUT equalization ontrols, the
ARCHIVER a ommodates any artridge from MC to MM with variable LOADING and
GAIN. Output is both RCA and balan ed XLR in either PHASE.

Operation
The Ar hiver has two separate stereo inputs, one of whi h an be strapped to mono
operation. Any artridge, from MM to MI to MC an be a ommodated using the
LOADING and GAIN ontrols. Be sure to set PHASE to mute when hanging GAIN, or loud
thumps may o ur at output.
TURNOVER and CUT ontrols allow for many equalization urves of older shella s. Use
this handy hart as a starting guide.
