Overview of the Logic Pro for Mac Surround Panner

You use the Surround Panner in Logic Pro for Mac to place track output signals at specific speaker positions. You can use the Surround Panner directly in a channel strip, but it is better to open it in a separate window.

You can open multiple Surround Panner windows simultaneously and save them in screensets. If the Link button  in the header of the Surround Panner window is enabled (Single mode), the window shows the surround mode and current settings for the selected channel strip.

The Surround Panner will appear as either Surround Panner (mono) or Surround Panner (stereo). This is determined by whether the channel strip input format (or the output format of the last effect plug-in) is mono or stereo. If it is surround, the pan control will be a Surround Balancer instead of a Surround Panner. All three pan controls have a different set of parameters. See Surround Panner parameters.

The Surround Panner is also used on bed tracks when mixing in Spatial Audio with Dolby Atmos. Object tracks, however, use the 3D Object Panner, which lets you position and move their signals in three-dimensional space.

Three types of surround pan and balance controls

A bed track can have three different channel modes, and the channel mode determines what pan control is available on the channel strip and in the track header.

  • Mono track: A mono track routed to a surround bus or output has a mono Surround Panner control with a single pan puck that positions the mono signal on the surround output.

  • Stereo track: A stereo track routed to a surround bus or output has a stereo Surround Panner control with a single pan puck. A shaded area around the puck indicates the spread of the stereo signal in the surround field.

  • Surround track: A surround track routed to a surround bus or output has a Surround Balancer control that functions differently from the Surround Panner. It passes the surround signal to the surround output without changing the position of the signal. It only changes the level on those output channels, depending on where you move the pan puck.

Note: The current surround format of a project is indicated by the dots on the Surround Panner (representing the ear-level speakers).

Figure. Three types of surround pan controls.

Surround Panner with Elevation slider

A vertical Elevation slider appears next to the pan control on a channel strip if the surround format of a project contains height channels (5.1.2, 5.1.4, 7.1.2, or 7.1.4). The slider corresponds to the Elevation parameter in the Surround Panner and Surround Balancer window.

Note: The Elevation slider is also available on any channel strip that uses the 3D Object Panner.

Surround Panner / Surround Balancer window

Although you can position the pan puck using the pan control of the channel strip or track header, you can access more parameters and controls when you open its corresponding Surround Panner window.

Open the Surround Panner window

  • In Logic Pro, double-click the Surround Panner control of a channel strip.

    The Surround Panner window provides a magnified view of the channel strip’s Surround Panner, and contains additional parameters.

Use the Surround Panner on mono input channel strips

If the channel strip input format is set to mono (or the output format of the last effect plug-in on that channel strip is mono), the window acts as a mono-to-surround panner.

The graphical surround field in mono-to-surround mode controls the surround routing of the input signal to speaker outputs. The level sliders and fields below the surround field provide independent control of the Center and LFE channel levels. The separation controls allow you to precisely control the separation between channels.

  • In Logic Pro, do any of the following:

    • Drag the puck in the graphical surround field to change the diversity and angle.

      • Circular movement changes the angle.

      • The distance from the center of the surround field changes the diversity.

    • Press and hold the Command key while moving the puck to lock the diversity value.

    • Press and hold the Control and Command keys while moving the puck to lock the angle value.

Use the Surround Panner on stereo input channel strips

If the channel strip input format is set to stereo (or the output format of the last effect plug-in on that channel strip is stereo), the window acts as a stereo-to-surround panner.

The graphical surround field in stereo-to-surround mode has three pan pucks: a puck for the left (L) signal, a puck for the right (R) signal, and a third puck (a dot), which controls both the L and R pucks as a group. It also offers a Spread field in the upper-right corner, which controls the stereo width of the signal.

Figure. Stereo-to-Surround Panner window.

In Logic Pro, do any of the following:

  • Drag the L or R puck in the graphical surround field to move the other pucks in a symmetrical fashion.

  • Drag the dot puck to move both the L and R pucks, while maintaining a given spread.

    • Circular movement changes the angle.

    • The distance from the center of the surround field changes the diversity.

  • Press and hold the Command key while moving the pucks to lock the diversity value.

  • Press and hold the Control and Command keys while moving the puck to lock the angle value.

The circular bars around the graphical surround field (blue for the left channel and green for the right channel) indicate which speakers will carry the respective signal source; the closer to the center a puck is moved, the wider its corresponding bar gets (the greater its diversity, in other words).

Use the Surround Balancer on surround input channel strips

If the channel strip input format is set to surround (or the output format of the last effect plug-in on that channel strip is surround), the Surround Panner turns into a Surround Balancer.

Source channels are passed on to their respective output channels (speaker positions) without any cross-panning or mixing. The pan control is represented by a single puck (a dot), which affects the multichannel source signal as a whole.

In Surround Balancer mode, the Separation parameters are not available and the Diversity parameter is replaced by Amount.

  • Drag the puck to change the relative volume balance of the source signal.

    • Circular movement changes the angle.

    • The distance from the center of the surround field changes the amount.

  • Press and hold the Command key while moving the puck to lock the amount value.

  • Press and hold the Control and Command keys while moving the puck to lock the angle value.
