S curve 131 Features
The Samson S curve 131 Graphic Equalizer utilizes state-of-the-art, Constant Q filtering technology for
precise tonal control. Here are some of it’s main features:
• The S curve 131 has 31 bands of equalization, with each frequency band representing 1/3 of
an octave in the 20 Hz to 20 kHz range.
• Constant Q circuitry ensures that the bandwidth of the selected frequency area stays the same
even when approaching maximum boost or attenuation. As a result, phase shifting and inter-
modulation distortion is greatly reduced, making for pristine sound.
• The S curve 131 can be set for either 6 or 12 dB of gain and attenuation for each of the fre-
quency bands.
• For monitor applications, the S curve 131 can be set for CUT ONLY mode providing up to 24dB
of attenuation.
• Ultra-low noise circuity ensures superb audio fidelity.
•Variable Low Cut Filter for removing rumble and floor noise can be adjusted from 80 to 400 Hz.
• Electronically balanced XLR and TRS inputs and outputs.
• Front panel, hard-wired, relay controlled Bypass switches (with dedicated Bypass LEDs) allow
the equalization circuitry and output level control to be activated or deactivated.
• Main Level control enables output signal to be attenuated or boosted for optimum signal-to
noise ratio.
• LED faders and 8 segment LED bar VU meters.
• Relay power-on circuitry prevents speaker “thumps” when the unit is turned on.
• Internal power supply ensures reliability and trouble-free operation.
• Standard 19" rack design (the S curve 131 requires only a single rack space) for easy integra-
tion into any traveling or fixed installation audio system.
• Optional security cover kit prevents EQ settings from accidentally being altered.
• All-steel chassis makes the S curve 131 eminently road-worthy.
• Three year extended warranty.
