EQ On / Off
The EQ on/off button – near the upper-left corner of the screen – allows for true bypass of the EQ circuitry
to ensure that there is no coloration of the signal if the EQ is not needed. When this button is disengaged,
the EQ controls have no effect on the signal. You may use this button to make an A/B comparison between
the EQ’d signal and the signal without EQ. Press this button to turn EQ on or off. It will illuminate green when
engaged and is gray when disengaged. Additionally, the EQ curve at the top of the channel fader switches
between green [engaged] and gray [disengaged].
Modern / Vintage
The modern/vintage button is located directly to the right of the EQ on/off button. It displays the EQ type
currently in use, with “Modern” as the default EQ. Tap this button to reveal the two EQ types, then tap the
EQ you would like for the selected channel. The image will change to reflect the EQ type chosen.
You can switch between EQ types while audio passes and the settings will match as closely as
possible, but the sound will change.
Polarity Invert
The polarity invert button [Ø] – located in the upper right hand corner of the screen, just below
the tools and presets buttons – allows for individual channel activation of 180˚ polarity inversion;
it is available on all input channels. Press the polarity invert button to turn polarity invert on or off.
It will illuminate green when engaged and is gray when disengaged.
