Direction Mixer
Logic Pro Direction Mixer overview
You can use Direction Mixer to decode middle and side audio recordings or to spread the
stereo base of a left/right recording and determine its pan position.
Direction Mixer works with any type of stereo recording, regardless of the miking technique
used. For information about the most common stereo miking techniques—AB, XY, and MS—
see Stereo miking techniques.
Direction Mixer parameters
• Input buttons: Set the input signal type. Use LR if the input signal is a standard left/right
signal. Use MS if the signal is middle and side encoded.
• Direction knob and field: Set the pan position for the middle—the center of the stereo
base—of the recorded stereo signal. When Direction is set to a value of 0, the midpoint
of the stereo base in a stereo recording is perfectly centered within the mix.
When you work with LR signals:
• At 90°, the center of the stereo base is panned hard left.
• At −90°, the center of the stereo base is panned hard right.
• Higher values move the center of the stereo base back toward the center of the
stereo mix, but this also has the effect of swapping the stereo sides of the recording.
For example, at a value of either 180° or −180°, the center of the stereo base is dead
center in the mix, but the left and right sides of the recording are swapped.
When you work with MS signals:
• At 90°, the middle signal is panned hard left.
• At −90°, the middle signal is panned hard right.
• Higher values move the middle signal back toward the center of the stereo mix, but
this also has the effect of swapping the side signals of the recording. For example,
at a value of either 180° or −180°, the middle signal is dead center in the mix, but
the left and right sides of the side signal are swapped.
