Professional Equalizer 2231

This is double 31 section equalizer which can range from ±6 dB to±15 dB for increase and decrease. With XLR RF filter, the input and output line terminals and 1/4" TRS interface, input gain range from -12dB to +12dB, 18 dB or octave of 40 Hz Bessel low frequency switching filter, chassis grounding/signal suspended ability, built-in power supply, safe and reliable.

  • Input interface: 1/4 inch TRS, XLR socket
