SETTING UP THE S curve 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
unmuted).

8.  Apply an input signal to the S curve 215  (if sending signal from a mixer output bus, drive the mixer’s
output meters at approximately 0 VU).  While the input signal is present, slowly raise the front panel
Level slider(s) to their center detented “0” points.  For best signal-to-noise ratio, the Level slider(s)
should be at or near the “0” point during normal operation. However, if the output signal is weak, use
the appropriate Level slider(s) to slightly boost the volume (to a maximum of 6 dB).  Conversely, if the
signal causes the front panel +18 LEDs to light, use the appropriate Level slider(s) to attenuate volume
as necessary.  In normal operation, the +18 LED(s) should not light at all; if they do, use the Level slid-
ers to lower the volume of the output signal so that they do not light at all (clipping not only sounds
awful, it can also damage speakers!).

9.  Experiment by moving each of the Equalizer sliders up and down, carefully listening to the audible
result on the audio signal.  Bear in mind that the very lowest and highest frequency areas may have lit-
tle or no effect on some signals.  If there is significant low frequency noise (rumble) in the signal,
engage the Low Cut switch(es) as necessary. As you work with the various front panel controls, press
the front panel Bypass switch(es) in and out from time to time in order to compare the effect of the
equalization curve you are creating with the original input signal.

10.  Once you’ve created the frequency curve required for your particular application (see the “About
Equalization” section on the following pages for more information), an optional locking security cover
(available from your local Samson dealer) can be placed over the front panel to make sure that your
settings are not inadvertently altered.

If you have followed all the steps above and are experiencing difficulties with any aspect of setting up
or using your S curve 215, you can call Samson Technical Support (1-800-372-6766) between 9 AM
and 5 PM EST, or contact your local distributor.
