- Single 31-band, 1/3-octave Constant Q frequency bands
- The 131s offers allows true 1/3-octave bandwidth control at all slider positions.
- Switchable boost/cut ranges of ±6 or ±12dB
- The 131s features a boost/cut switch that allows you to select which of the two boost/cut ranges the equalizer will use, either ±6 dB or ±12 dB. The red LED lights when the ±12 dB range is selected.
- Bypass switch
- Bypass the EQ with a simple press of the 131s's bypass switch that is conveniently located on the front panel.
- ±12 dB input gain range
- The 131s is capable of -12 dB to +12 dB of gain.
- 4-segment LED ladders for monitoring output levels
- Easily determine the processing status of the 131s via the front panel LEDs.
- XLR and TRS Inputs and Outputs
- The 131s has balanced inputs and outputs that can be used with any balanced or unbalanced line-level device.
- Frequency Response of <10Hz to >50kHz
- The 131s is able to easily respond and adjust for a speaker's frequency response based on its amazing 10 Hz to 50 kHz frequency response range.
- Dynamic range of greater than 108dB
- The 131s's wide dynamic range ensures clean, clear audio regardless of the audio content being processed.
