Here are some of it’s main features: • The S curve 231 is a two channel equalizer and each channel provides 31 bands of equaliza-tion, with each frequ...

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 sliderallow you to cut or boost each frequency area. As described below, the exact action of the Equali...

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 theRANGE switch (see #7 below). The Cut Only switch should be used when you need to notch out ...

13 Using the S cur ve 231 with an RTA An RTA (Real Time Analyzer) is a device which measures the relative levels of multiple frequencyareas. This device, in conjunction with a pink noise generator, is the perfect companion for your Scurve 231. Together with a high quality microphone, these tools all...

14 Using the S cur ve 231 to Remove Feedback One of the most important applications for the S curve 231 is removing feedback from an onstagemonitor system. This procedure is sometimes called “ringing out,” since feedback usually begins witha slight ringing sound at the resonant frequencies where the...
