Congratulations on purchasing the Samson S curve 131 1/3 Octave, single channel, 31 Band Constant
Q Graphic Equalizer!  Although this product is designed for easy operation, we suggest you take some
time out first to go through these pages so you can fully understand how we’ve implemented a number
of unique features.

The S curve 131 is a professional quality signal processor that gives you precise tonal control over a
mono audio signal.  Center detented sliders with LED illumination allow you to selectively cut or boost
selected frequency areas by as much as 24 dB.  Front panel controls include output level sliders, a
variable Lowcut filter, as well as Cut Only, Range and Bypass switches. The rear panel provides elec-
tronically balanced inputs and outputs on 1/4-inch and XLR connectors.  Thanks to low noise circuitry,
the S curve 131 can be used in a wide variety of applications, including live performance (in conjunc-
tion with either Front Of House or monitor mixers), in broadcast environments, or for recording.

In this manual, you’ll find a more detailed description of the features of the S curve 131, as well as a
guided tour through the front and rear panels, step-by-step instructions for using the unit, suggested
applications for use with a patch bay, a Real Time Analyzer (RTA) or for ringing out monitor systems,
reference appendices, and full specifications.

You’ll also find a warranty card enclosed—please don’t forget to fill it out and mail it so that you can
receive online technical  support and so we can send you updated information about other Samson
products in the future.  Also, be sure to check out our website (http://www.samsontech.com) for com-
plete information about our full product line.
