Dual Channel 31-band Graphic Equalizer/Limiter with Type III Noise Reduction
Series: 20
Model: 2231
Part #: DBX2231V
- Revolutionary instant encode/decode Type III noise reduction in-circuit at the push of a button
- Increases S/N ratio by up to 20dB
- Patent-pending PeakPlus limiter threshold range from 0dBu to +24dBu (off) can transparently tame the wildest hits or the subtlest nuances of any signal
- Four segment LED bargraph for both gain reduction and output level offers the most comprehensive visual feedback available
- Status LEDs offer visual feedback for all settings on the front panel
The 2231 graphic equalizer shall be a mono 31-band type with frequency centers on standard ISO 1/3 octave frequencies ranging from 20Hz to 20kHz. The boost/cut range shall be switchable via a recessed front panel switch to either +/-6dB or +/-15dB and the selected range shall be indicated on the front panel by either of two LEDs. Low-noise equalization sliders having a 45mm travel shall be utilized having center detents at 0dB. The equalizer shall have a front panel 41-detent rotary input gain control having a +/-15dB range. Bypassing the equalizer section of the signal path shall be accomplished via a front-panel switch having a corresponding LED to indicate when it is bypassed. A 40Hz low-cut Bessel filter with 18dB/octave slope shall be insertable in the signal path via a front panel recessed switch and shall have an LED to indicate when the filter is active. The graphic equalizer shall incorporate dbx Type III™ Noise Reduction providing up to 20dB of broadband noise reduction, having a front panel switch to enable the noise reduction and an LED to indicate when it is active. The equalizer shall also be equipped with a dbx PeakPlus limiter system. Electronically balanced/unbalanced inputs shall include 1/4" TRS, female XLR, and screw terminal barrier strip, while servo-balanced/unbalanced outputs shall include 1/4" TRS, male XLR, and screw terminal barrier strip shared with the input.
