6 SETTING UP THE S cur ve 215 SETTING UP THE S cur ve 215 Setting up your S curve 215 Graphic Equalizer is a simple procedure which takes only a few minutes: 1. Remove all packing materials (save them in case of need for future service) and decide where the unit is to be physically placed—it can be used free-standing or mounted in a standard 19&q[...]

SETTING UP THE S cur ve 215 7 7. Press the front panel Power switch in order to turn on the S curve 215. Press the Bypass switches in to activate the equalizer . Note that audio signal will be muted for approximately five seconds until the relay power-on circuitry is activated (at which time you’ll hear a click and the audio signal will be unmute[...]

8 S cur ve 215 Sy stem Configurations Using the S curve 215 with Active Speakers In this example the mixer’s left and right outputs are connected to the S curve 215’s Channel 1 and Channel 2 inputs. Then, the S curve 215’s Channel 1 and Channel 2 outputs are connected to the inputs of the active (self-powered) loudspeakers. Using the S curve [...]

S cur ve 215 Sy stem Configurations 9 Using the S curve 215 for Mains and Monitors Using the S curve 215 in Insert Points You can use the S curve 215 in your mixer’s insert points if you want to equalize one stereo, or two mono channels, individually in the mix. In this example, the S curve 215’s Channel 1 INPUT and OUTPUT are inserted on a pia[...]

The mixer’s left and right outputs are connected to the first S curve 215’s Channel 1 and Channel 2 inputs for the main PA speakers. Then, the first S cur[...]

11 The S curve 215 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... Every naturally occurring sound consists of a broad range of pitches, or frequ[...]

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. This is because each piece of equipment may operate at a marginally different voltage (this difference is called potential ) and, when two devices at slightly different potential are physically con[...]

13 Using the S cur ve 215 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 215. T ogether with a high quality microphone, these tools allow you to fine tune the overall fre- quency[...]

14 Using the S cur ve 215 to Remo ve Feedback One of the most important applications for the S curve 215 is removing feedback from an onstage monitor system. This procedure is sometimes called “ringing out,” since feedback usually begins with a slight ringing sound at the resonant frequencies where the loop between microphone and speaker is lou[...]
