low noise circuitry, the S curve 231 can be used in a wide variety of applications, including live performance in conjunction with either Front Of House or monitor mixers, in broadcast environments, or for recording. The S curve 231 is a two channel equalizer and each channel provides 31 bands of equalization, with each frequency band representing 13 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 intermodulation distortion is greatly reduced, making for pristine sound. The S curve 231 can be set for either 6 or 12 dB of gain and attenuation for each of the frequency bands. For monitor applications, the S curve 231 can be set for CUT ONLY mode providing up to 12dB of attenuation with full slider range. Ultra low noise circuity ensures superb audio fidelity. Variable Low Cut Filter for removing rumble and floor noise can be adjusted from 15 to 200 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.
