Proust is a comact trile assive filter with fixed cutoff
freuencies for hihass and lowass filterin. Itis asimle
RC filter with 2 oles for HP and 1 ole for LP. There is
a dro in sinal strenth, because the sinal is filtered
assivel. No ower connection is reuired. When the
sinal oes throuh both HP and LP staes, it creates
a BP filter.
Simle fixed filters can hel ou clean u our final mix
and make room for each sound, or the can be used for
filterin noise and other sinals when eneratin drum
sounds for instance. Connectin these filters into an
feedback chain can result in somethin reall secial.

These re the three independent filters. Ech one
is tuned differently. The cutoff frequencies re
indicted by the print on the front pnel.
When  signl is connected to the connector you
cn tke the highpss filtered signl from nd
 bndpss filtered signl from . When  signl
is connected to you cn tke  lowpss filtered
signl from . Becuse this is  pssive design,
you cn try to pss signls thru the stges in ny
direction to check for vrious results.
