Linking Auxes – As mentioned previously, two separate mono auxes may be linked together into a single
stereo aux. This is ideal for using in-ear monitors or other stereo output destinations such as broadcast feeds,
recording devices and more. When linked, the level control, graphic EQ and output compressor/limiter are
adjusted with a single set of controls!
Linking auxes is easy. First you need to select the aux you want to link. Now tap the aux's Master ID button;
you will see an option to "Link Aux X over Aux X". Tap it! A popover will display asking you to confirm. A visual
of these steps is displayed below. Follow the same steps outlined above to unlink auxes.
Unlinked
Odd-numbered auxes will link to the next (even-numbered) aux [1-2, 3-4, 5-6], while
even-numbered auxes will link to the previous (odd-numbered) aux [6-5, 4-3, 2-1].
The linked over aux will take on all of the attributes [graphic EQ settings, output compressor/
limiter settings, aux send output routing, etc.] of the tapped Master ID (aux) button. In other
words, if you link aux 1 over 2, the resulting stereo aux will take on all of the settings of aux 1.
However, if you link aux 2 over aux 1, the resulting stereo aux will take on all of the settings of
aux 2.
