Esoteric Sound Surface Noise Reducer Brochure

ESOTERIC SURFACE NOISE REDUCER FOR ALL PHONO RECORDS

YOUR PHONOGRAPH RECORDS ARE NOT GOING TO GET QUIETER

SURFACE NO ISE REDUCER SPECIFICATIONS

The Surface Noise Reducer eliminates or reduces the clicks and pops found on most types of
phonograph records. Its circuit topology employs the latest in modern digital integrated circuits
and a design algorithm which can identify and remove many clicks and pops found on Lp's and
even 78's and other vintage recor ds. It can often improve the quality grade of records by several
grades. It will cause minimum degradatio n to either audiop hile or vintage r ecords and is suitable
for inclusion into advanced audiophile systems where phonograph records are used. While use
of a graphic equalizer or "scratch filter" to remove ticks and scratches is somew hat effective, such
filters reduce or eliminate the highs found on reco rds. The E soteric Surface Noise R educer acts
only on the click or po p without effecting program material. The Surface Noise Reducer is also
very effective in reducing ignition noise from FM radio broadcasts. Send for our 44 track demo
