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.
>
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.
