Stereo options

One of FabFilter Pro-Q 2's best features is that it's very easy to equalize both stereo channels in a different way. This is a great

way to surgically remove unwanted sound artefacts, or even to add stereo effects.

To make this even more powerful, Pro-Q 2 offers both Left/Right and Mid/Side channel modes. In the default Left/Right mode, each

EQ band works either on both stereo channels, or on the left or right channel only. This is controlled by the stereo options at the

lefthand side of the

band controls:

Click the L or R button to let the selected bands affect only the left or right channel.

Click the stereo button (in the middle) to let the selected bands affect both stereo channels.

Click the split button underneath the buttons to duplicate the selected band, making two identical copies, one operating only

on the left channel and one operating on the right channel. This makes it very easy to slightly adjust one of the channels.

As soon as one or more of the EQ bands are operating on a single channel, the EQ display switches to per-channel mode, where it

shows two overall frequency response curves: a white one for the left channel, and a red one for the right channel, as shown by

the picture above.

Mid/side mode

The Channel Mode parameter in the bottom bar switches between Left/Right and Mid/Side operation. In Mid/Side mode, the

incoming stereo signal is converted into Mid (mono) and Side parts, which you can then easily filter independently. This is often an

even better way to fix artefacts or modify stereo information because it represents the stereo signal in a more natural way.

In Mid/Side mode, everything works as described above, except that the stereo options above change to M/stereo/S buttons. In

addition, the display shows the two overall frequency response curves in white (Mid) and light blue (Side) so you know at a

glance in which mode Pro-Q 2 is currently operating.
