Chapter 11: Matrix and Personal Q Mixers 101
Configuring Matrix and PQ Mixers
The 12 Inputs for each Matrix and PQ mixer can be any com-
bination of these 35 potential sources:
• 24 shared Aux and Group sources
• 3 Mains sources (LCR or LR+M)
•8 User Input sources
User Inputs can be input channels, FX Returns, physical stage
audio or FOH audio inputs, or inputs from Pro Tools playback
options. In addition:
• One or more of the 8 available user inputs can be sent to
one or more Matrix or PQ mixers.
• Input source assignment and user input assignment can
be stored on a per-snapshot basis.
• The input sources for Matrix and PQ mixers are config-
ured as Pre- or Post-Fader in the Pickoffs tab of the Op-
tions page.
• Input labels (1–8, Left, Right, C/Mono and User) are only
intended as a guide. In use, any input source can be as-
signed to any mixer input (for example, Left doesn't al-
ways have to be assigned to the Left input of a mixer).
Configuring Aux, Group and Mains Pickoffs
To configure Auxes, Groups, and Mains pickoffs for the Matrix
and PQ mixers:
1 Put the system in Config mode.
2 Go to the Options page and click the Pickoffs tab.
3 Under Matrix and PQ Sources, configure Aux, Groups and
Mains (LCR or LR+M) as pre- or post-fader.
Linking and Unlinking Pairs to form Stereo
Matrix Outputs
The eight mono Matrix mixers can be linked in odd/even pairs
to form up to four stereo-linked pairs of matrix outputs. A
combination of mono and stereo-linked Matrix mixers is pos-
sible. Odd-even matrix pairs are linked and unlinked using
on-screen controls in the Options > Busses page.
To stereo link Matrixes:
1 Put the system into Config mode.
2 Go to the Options > Busses page.
3 In the Matrix section, click Edit.
4 Click to enable the Link between any two adjacent
(odd/even) Matrixes.
5 Click Apply. (Click Cancel to exit Edit mode without
changes.)
When a matrix pair is linked, the even-numbered channel in-
herits all parameter settings of the odd-numbered channel.
The matrix mixer changes to a stereo matrix mixer:
• A Pan control is added to each matrix mixer input source.
• All input sources are panned center upon linking.
Plug-in assignments to the formerly mono matrix channels
are lost, including all snapshot references.
Unlinking Matrixes
To unlink a pair of Matrixes:
1 Put the system into Config mode.
2 Go to the Options > Busses page.
3 Click Edit in the Matrix section.
4 Click to unlink the desired Matrixes.
5 Click Apply.
When a Matrix pair is unlinked the even-numbered channel
again inherits all parameter settings of the odd-numbered
channel.
Pre-existing plug-in and GEQ routing may be affected when
the matrix link state is changed. An alert dialog warning of
data loss is shown prior to performing the link or unlink op-
eration. Click OK to complete the link operation, or click Can-
cel to cancel without changes.
Configuring pickoff points may cause a momentary loss of
audio, and therefore cannot be changed in Show mode.
Linking Matrixes is accomplished using the same Edit and
Apply methods used for stereo linking Auxes.
Editing the link status of a Matrix pair in the Options > Busses page.
