The Direction Mixer works with any type of stereo recording, regardless of the miking
technique used. For information about XY, AB, and MS recordings, see Getting to Know
Stereo Miking Techniques.
• Input buttons: Click the LR button if the input signal is a standard left/right signal, and
click the MS button if the signal is middle and side encoded.
• Spread slider and field: Determines the spread of the stereo base in LR input signals.
Determines the level of the side signal in MS input signals. See Using the Direction
Mixer’s Spread Parameter.
• Direction knob and field: Determines the pan position for the middle—the center of
the stereo base—of the recorded stereo signal. See Using the Direction Mixer’s Direction
Parameter
Using the Direction Mixer’s Spread Parameter
The Direction Mixer’s Spread parameter behavior changes when fed LR or MS signals.
These differences are outlined below:
When working with LR signals, the following applies to the Direction Mixer’s Spread
parameter:
• At a neutral value of 1, the left side of the signal is positioned precisely to the left and
the right side precisely to the right. As you decrease the Spread value, the two sides
move toward the center of the stereo image.
• A value of 0 produces a summed mono signal—both sides of the input signal are routed
to the two outputs at the same level. At values greater than 1, the stereo base is
extended out to an imaginary point beyond the spatial limits of the speakers.
The following applies when working with MS signals:
• Values of 1 or higher increase the level of the side signal, making it louder than the
middle signal.
• At a value of 2, you hear only the side signal.
