The DEQ-230 is a professional digital parametric/graphic 2 x 30 band stereo equalizer with high-quality DSP processors and digital converters. The variable Q factor of the filters in each equalizer allows for a very fine adjustment and thus a matching to existing acoustic conditions.
Additionally, the DEQ-230 also features: delay, RMS compressor and high-pass/low-pass filters.
Each feature and adjustment can be edited and stored in individual presets directly at the unit or via the intuitive graphical user interface at the PC or via the USB interface or RS-485 interface.
