Parametric EQ

The Gemini features a built-in 4 band parametric EQ that can be configured using the Neuro App.

Different EQ settings can be saved for each of the three effect types, as well as for the user preset.

The EQ consists of four independently configurable bands:

 Band 1: Low Shelf

 Band 2: Peaking (a.k.a. Bell / Band)

 Band 3: Peaking (a.k.a. Bell / Band)

 Band 4: High Shelf

Each band has configurable frequency, boost/cut, and Q (bandwidth).

A simple example of these four bands in action is shown in the graph below. In this example, Band 1

is a low shelf filter at 100 Hz with a 6 dB cut, Band 2 is a peaking filter at 620 Hz with a 3 dB cut and

relatively high Q, Band 3 is a peaking filter at 3 kHz with a 1.5 dB boost and relatively low Q, and Band

4 is a high shelf filter at 10 kHz with a 2.5 dB cut.

Using the Neuro App, Band 1 (Low Shelf) can optionally be configured as a high pass filter, and Band

2 (High Shelf) can optionally be configured as a low pass filter.
