Channel Strip EQ
The Channelstrip EQ provides a very wide range of frequency and gain changes ( up to 15dB! ) to help tame your tracks. The high and low bands are shelving filters for general tone sculpting, while the middle band is a “proportional Q” bandpass design.
The proportional-Q design was used in the original Harrison consoles to allow an engineer to use the EQ as either a subtle tone shaping tool, or a steep filter problem-solver, with only 2 knobs. As the gain is progressively increased (or cut), the bandwidth becomes progressively narrower (“Q” increases). A typical technique to eliminate an unwanted tone or resonance is to increase the gain to maximum cut, sweep the frequency to find the offending sound, and then turn the gain to the minimum cut required to “notch” out the unwanted frequencies (remembering that reducing the amount of cut widens the bandwidth and attenuates a wider range of frequencies).
Gain Range +/- 15dB
