SKU: DBXIEQ31 Category:

dbx iEQ-31 not only includes two 31-band channels of 1/3-octave equalization but it also gives you +12 dB input gain range, switchable +6 or +15dB boost/cut range and 40mm faders with nonconductive nylon sliders.

The Advanced Feedback Suppression (AFS) feedback elimination module is provided. The AFS uses Precision Frequency Detection and state-of-the-art processing to determine the exact portions of a given frequency that is causing feedback without removing approximately half of the signal power, as is the case with the traditional method of moving the offending frequency’s slider.

In addition, the iEQ-31 provides dbx Type V noise reduction and PeakStopPlus limiting for taming unwanted peaks. XLR, 1/4″ and Euroblock inputs and outputs and an intuitive user interface with comprehensive output and gain reduction metering round out this professional EQ that is perfect for touring applications or in installed sound venues.
