Vintage Graphic EQ is based on a classic mixing console module. The 10 EQ bands provide 12 dB of cut/boost. It emulates the Proportional Q design of the original device, which widens filter bandwidth at lower boost/cut levels and narrows filter bandwidth at higher boost/cut levels.
Frequencies aren’t fixed at the default values, and all bands can be proportionally scaled to provide more focus on a portion of the overall frequency spectrum.
The standard frequency values can be changed by dragging the Tune field.
In/Out switch: Turn the EQ circuit on or off.
Tune field: Drag to set the frequency of all band sliders. Scaling of frequencies is proportional. This can be used to tune the bands to your project key.
Tip: When set to +12 you can boost 32 kHz which results in a very smooth high-end boost.
EQ band sliders: Drag to cut or boost the selected frequency of the incoming signal by ± 12dB.
