The very open and natural sound character of the elysia skulpter 500 can be shaped by two independent combinations of saturation and specially tweaked filter curves:
Shape One: Instruments
The first ingredient to achieve that big, fat sound is adding harmonics (THD). The intensity of this saturation is determined by the input level and the amount of preamp gain. At the same time, a pre-tailored EQ curve with a high frequency cut starting around 4 kHz is applied to the signal. The resulting sound is huge, with a massive body but no harsh peaks at all.
Shape Two: Vocals
Vocals benefit from the same saturation enhancement; and, like a tube-like characteristic curve, this results rather in musical soft clip limiting than in actual distortion. The preset EQ curve is of course a different one for vox, with up to 10 dB of high mid boost around 4.5 kHz.
The corresponding potentiometer is actually a mix controller, so that any desired amount of this effect can be blended to the original signal, while in the fully left position the original remains completely unaffected.
The sound shaping potentials of the elysia skulpter 500 can help to produce a “finished” sound already while recording – especially in combination with the onboard dynamics section.
