2 Congratulations on purchasing the Samson S curve 231 dual channel,1/3 Octave, 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.
3 S cur ve 231 F eatures The Samson S curve 231 Graphic Equalizer utilizes state-of-the-art, Constant Q filtering technology for precise tonal control.
4 1 Equalizer level sliders - Independent Equalizer sliders are provided for each frequency area (The S curve 231 provides 31 frequency areas).Calibration markings on either side of each Equalizer slider allow you to cut or boost each frequency area.
5 CUT ONLY switch - When pressed in, the LED switch lights and all the Equalizer sliders serve to attenuate their frequency areas only (there is no boost) by up to 6 or 12 dB, depending upon the setting of the RANGE switch (see #7 below).
6 SETTING UP THE S cur ve 231 SETTING UP THE S cur ve 231 Setting up your S curve 231 Graphic Equalizer is a simple procedure which takes only a few minutes: 1.

8 S cur ve 131 Sy stem Configurations Using the S curve 231 with Active Speakers In this example, the mixer’s stereo output is connected to the S curve 231’s inputs. Then, the S curve 231’s outputs are connected to the inputs of each active (self-powered) loudspeaker.
S cur ve 131 Sy stem Configurations 9 Using the S curve 231 for Mains and Monitors Using the S curve 231 in Insert Points You can use the S curve 231 in your mixer’s insert points if you want to equalize two mono channels individually in the mix.
10 S cur ve 131 Sy stem Configurations U sing T wo S curve 231’ s for Mains and Monitors In this example, two S curve 231’s are used for the stereo main and for the 2-channel monitor mix. The mixer’s left and right outputs are connected to the first S curve 231’s inputs for the main PA speakers.
11 The S curve 231 gives you fine control over shaping a sound, using a process called equalization . But there are few areas of sound engineering more misunderstood than equalization, and, just as good EQ can really help a sound, bad EQ can really hurt it, so read on.
Grounding T echniques Hum and buzz are the biggest enemies you face when interconnecting a large number of different pieces of equipment to one another.
13 Using the S cur ve 231 with an RT A An RT A (Real T ime Analyzer) is a device which measures the relative levels of multiple frequency areas. This device, in conjunction with a pink noise generator , is the perfect companion for your S curve 231.
14 Using the S cur ve 231 to Remo ve F eedback One of the most important applications for the S curve 231 is removing feedback from an onstage monitor system.
