Frequently asked questions
What's the main difference between 15-band and 31-band equalization?
The 215s uses 2/3-octave spacing (15 bands) for broad, general corrections across the frequency spectrum. The 231s uses 1/3-octave spacing (31 bands) for much finer, more granular control over specific problem frequencies. The 231s lets you target narrower frequency ranges with precision.
Which one is better for live sound reinforcement?
Both handle live sound well, but the 215s excels in time-sensitive environments where you need fast, intuitive real-time adjustments and compact rack space. The 231s suits fixed systems where you set it once and leave it, benefiting from its surgical precision on permanent installations.
Do they have the same dynamic range and frequency response?
Yes—both offer 112 dB dynamic range, 10Hz to 50kHz frequency response, switchable ±6 dB or ±12 dB boost/cut, and a 12dB per octave low-cut filter. The only audio-spec difference is the number of bands and their spacing.
What about connectivity differences?
The 215s does not specify balanced XLR/TRS I/O in its description. The 231s explicitly features balanced XLR and TRS inputs and outputs on both channels, making it more suitable for professional audio chains where impedance matching matters.
