HEAR EQ and how it works
ReQ·131 has the option to listen to the affect of the EQ itself, via the HEAR EQ button, without the
original content. This can be beneficial to help identify if certain instruments or sounds should be
brought forward or sent to the back of the mix, in any of the signal path modes.
In L/R mode;
When you turn HEAR EQ on with all faders set to zero, you should hear no signal at all. This is
because the EQ is having no effect on the final audio
If you raise any of the faders above the zero line, you will hear portions of audio based on that
specific frequency centre; this will indicate what you are ADDING to the final signal.
If you lower any faders below the zero line, you will hear portions of audio based again on that
specific frequency centre, with the difference that this will be the audio REMOVED from the final
signal. NOTE: this will invert audio frequencies whilst in HEAR EQ mode, so even though it
sounds alike the original, the phase relationship with the original is an inversion.
This can be very convenient to tell what you are adding or removing, giving you more insight to
what the equalisation is doing to your final signal.
In MID or SIDE mode;
when you turn HEAR EQ on with all faders set to zero, you should hear only the signal of your
chosen path, either MID signal or SIDE signal only, without any equalization effect applied. This
can be useful to aid with better decisions to decide what will be equalised in your chosen mode.
It works very much like standard L/R mode with HEAR EQ off, except you are listening to an
EQ’d version of the MID or the SIDE signal.
Raising any of the faders will increase the level of the specific frequency centre on the chosen
signal path only, without affecting the unprocessed side (ie boosting MID while leaving SIDE
alone
Lowering any of the faders will decrease the level of the specific frequency centre on the chosen
signal path only, without affecting the unprocessed side (ie boosting MID while leaving SIDE
alone
When you turn HEAR EQ off, you will hear your EQ’d signal path put back with the unprocessed
signal
Which ever mode you are using, when you use the WET/DRY knob as a balance, you will be either:
Mixing original stereo signal with equalized stereo signal
Mixing original MID signal + unprocessed SIDE signal with equalized MID signal + unprocessed
SIDE signal
Mixing original SIDE signal + unprocessed MID signal with equalized SIDE signal +
unprocessed MID signal
HEAR EQ can also be used creatively if you so desire, especially useful for sound design
