The Apex dBQ-zero EQ on each channel, the 30-band constant-Q graphic section is completed with a filter section consisting of a high-pass filter, high and low shelving equalizers and two notch filters. Shelving filters add warmth and colour to the mix. A typical application for our frequency adjustable high-pass filter is to remove hum or vibration transmitted by turntables. Notch filters allow fast and easy removal of noise or potential feedback frequencies.
Constant-Q design preserves filter bandwidth independently from the amplitude control settings and therefore minimizes the adjacent band interaction. Constant-Q reinforces the graphical representation by the front panel faders of the actual frequency response.
