Learn how to balance and pan audio for stereo and 5.1 in your Premiere Pro projects using the Audio Mixer.

You are watching: True or false: a mono audio track can never be panned to the left or right.

Bydefault, all audio tracks output to the sequence master audio track.However, you can also create submix tracks. You can output audiofrom any track to a submix track. You can then out put audio froma submix track to a Master Track. You can use an audio track asan input for a submix track or for the Master Track. You can usea submix track as an output for an audio track and as an input fora Master Track. Different tracks in the same sequence can have differentnumbers of channels. For example, you can send the output from amonaural audio track to a stereo submix track, and then send theoutput from the stereo submix track to a 5.1-channel Master Track.

If the number of channels differs between an input track andits output track, you determine how much each of the channels inthe input track feeds each of the channels in its output track.For example, you can send 80 percent of the signal from a monauralaudio track to the left channel of a stereo submix track, and 20 percentto the right channel. This is balancing. You balancethe audio to a stereo output track with Left/Right Pan dials inthe Audio Track Mixer. You balance the audio to a 5.1 output trackwith 5.1 Panner controls in the Audio Track Mixer.

In the Audio Track Mixer, a Left/Right Pan dial appears in atrack only when you select a stereo track as the output for thetrack. A 5.1 Panner control appears in a track only when you selecta 5.1-channel track as the output for the track. The relation betweenthe number of channels in an audio track and the number of channelsin the output track (often the master track) determines whetherthe pan and balance options are available for an audio track.

Panning is the moving of audio from one output channelto another, over time. For example, if a car drives from the rightside of a video frame to the left, you can pan the channel containingthe car audio so that it begins on the right side of the screenand ends on the left.

Note: If necessary, you can balance a clip by applying the Balanceaudio effect. Do so only after you determine that track balancingisn’t sufficient.

In the Audio Track Mixer, the number of level meters in a trackindicates the number of channels for that track. The output trackis displayed in the Track Output Assignment menu at the bottom ofeach track. The following rules determine whether a track’s audiocan be panned or balanced in its output track:

When you output a mono track to a stereo or 5.1 surroundtrack, you can pan it.

When you output a stereo track to a stereo or 5.1 surroundtrack, you can balance it.

When the output track contains fewer channels than in theother audio tracks, Premiere Pro downmixes the audio to the numberof channels in the output track.

When an audio track and the output track are mono or whenboth tracks are 5.1 surround, panning and balancing aren’t available.The channels of both tracks correspond directly.

While themaster audio track is the default output track, a sequence can also includesubmix tracks. Submix tracks can be both an output destination of otheraudio tracks and an audio source to the master track (or other submix tracks).Therefore, the number of channels in a submix track affects thepan or balance controls available in tracks that output to it, andthe number of channels in the submix output track affect whetherpanning or balancing is available for that submix track.

The Audio Track Mixer provides controls for panningand balancing. A round knob appears when a mono or stereo trackoutputs to a stereo track. You rotate the knob to pan or balanceaudio between the left and right output track channels. A squaretray appears when a mono or stereo track outputs to a 5.1 surroundtrack. The tray depicts the two-dimensional audio field createdby 5.1 surround audio. You slide a puck within the tray to pan orbalance audio among the five speakers, which are represented bypockets around the edge of the tray. The tray also includes controlsfor adjusting a 5.1 surround audio track’s center channel percentageand subwoofer volume. No pan control appears if a track outputsto a submix or master track that contains the same number of channels orfewer; therefore, a pan or balance control is never available fora 5.1 surround track. A master track doesn’t contain a pan or balancecontrol because it’s never routed to another track. However, panningor balancing an entire sequence is possible when you use the sequenceas a track in another sequence.

You can vary the pan setting over time in the Audio Track Mixer,or in a Timeline panel by applying keyframes to a track’s Pan options.



Note: For best results monitoring pan or balance settings,make sure that each of the computer or audio card’s outputs is connectedto the correct speaker, and make sure that positive and negativewires are connected consistently across all speakers.

Drag the pan control knob or the valuebelow the knob.

Click the value below the pan control knob, typea new value, and press Enter (Windows) or Return (Mac OS).

When you work with a sequence that contains an adaptive/multichannel master audio track, you can either click the Set Track Output Channel Assignments button or right-click the track header and select the Track Output Assignment option to assign output channels. The Track Assignment dialog box that appears allows you to mark your mapping on the matrix.


Note: Direct Output Assignment button allows you to mark your mapping on the matrix and the labels right next to it lets you do a quick inspection of the mappings.
