GENERAL DESCRIPTION

The S•Curve 131 is a professional quality equalizer that gives you precise tonal control over a mono audio signal. Center detented sliders with LED illumination allow you to selectively cut or boost selected frequency areas by as much as 12 dB. Front panel controls include output level sliders, a variable Lowcut filter, as well as Cut Only, Range and Bypass switches. The rear panel provides electronically balanced inputs and outputs on 1/4-inch and XLR connectors. Thanks to low noise circuitry, the S•Curve 131 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.

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 intermodulation 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 frequency bands.

CATEGO RY

> For monitor applications, the S•Curve 131 can be set for CUT

ONLY mode providing up to 12dB of attenuation.

> 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.

> 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 integration into any traveling or fixed installation audio system.

> All-steel chassis makes the S•Curve 131 eminently

road-worthy.

> Three year extended warranty.

ARCHITECT’S & ENGINEER’S SPECIFICATIONS

The Samson S•Curve 131 shall be a single channel 31 band equalizer. It shall have both XLR and 1/4 inch inputs and outputs. The front panel controls shall include 31, 20mm faders for equalizing the audio signal. Controls shall also include a master volume fader which can be used as a 0 to 10 main fader. Other controls available are cut only mode, a range switch with either 6dB or 12 dB of cut or boost, bypass, and a variable (15Hz to 200Hz) high pass filter with 12dB of cut. A standard IEC power cable shall be supplied for AC power.
