DBX 2231 Graphic Equalizer

Barely used and tested. Specs: dbx Type III™ Noise Reduction Switch: The switch engages the dbx Type III™ Noise Reduction circuit within the EQ. Input Gain Control: This control sets the signal level to the equalizer. It is capable of -12dB to +12dB of gain. EQ Bypass: This switch removes the graphic equalizer section from the signal path. EQ Bypass LED: This red LED lights when the EQ is in bypass mode. Boost/Cut Range Selection Switch and LEDs: This switch selects which of the two boost/cut ranges the equalizer will use, either ±6dB or ±15dB. Output Level Bar Graph: These four LEDs indicate output level of the equalizer. Clip LED: This LED lights whenever any internal signal level reaches 3dB below clipping. Gain Reduction Meter: These four LEDs indicate the amount of gain reduction being induced by the setting of the PeakPlus™ limiter threshold control. PeakPlus™ Limiter Threshold Control: This control engages the PeakPlus™ limiter. dbx Type III™ Noise Reduction LED: The yellow LED lights when the dbx Type III™ Noise Reduction circuit is activated via the Noise Reduction Switch. Frequency Band Slider Controls: Each one of these slider potentiometers will boost or cut at its noted frequency by ±6dB or ±15dB. Low Cut Enable Switch: The LOW-CUT switch inserts or removes the 18dB/octave 40Hz Bessel low-cut filter from the signal path.
