THREE NOISE REDUCTION SYSTEMS IN ONE
for use with modern stereo LP records or vintage 78s

The Rek-O-Kut De-Hisser is actually three products in one: a background hiss reducer, a left/right groove wall selector for mono records, and a low frequency noise filter (rumble filter).  Easily installed thru the external tape monitor circuit or your preamplifier/receiver or via the SuperConnector.

GROOVE WALL SELECTOR switch permits you to select the least noisy groove wall of a mono record. In addition, The Rek-O-Kut De-Hisser features a unique circuit which cancels out rumble and similar noises that are common to both groove walls. Other switching circuits (left only or right only) permit low frequency noises (rumble) to be heard unimpeded. Our added circuitry removes the rumble and not the bass.

HISS REMOVAL is accomplished not by a commonly used, variable hi-cut circuit, but by selecting band passes within the high frequency spectrum that accommodate the program material. This results in almost no audible pumping of hiss with program material and excellent performance even with spoken word. In addition, there are no digital artifacts as associated with computer software noise reduction schemes. 10 dB of hiss reduction is available for both vintage records and modern, stereo LPs.

THE LO-CUT switch can select two amounts of low frequency noise attenuation. The 40 Hz position will suffice for many noise plagued LP records and 78s, while the 80 Hz position may prove useful with old acoustic records, records with hum, or records requiring severe bass boost.
