EQ1A Equalizer


EQ1A is a super smooth, analog modelled equalizer, with minimal phase coloration. It features a high pass filter with variable Q, frequency sweepable low and high shelf filters, and sweepable low and high peak filters with variable Q. A bypass switch is available for each filter section for increased flexibility.

The interface takes it’s inspiration from classic analogue outboard equalizers, with all controls in easy reach. And the CPU efficient design allows for high instance counts, making it a versatile EQ for all tasks.
