Legacy AXS API
Stereo Program Bus Masters and Master Faders
The Legacy AXS is equipped with three stereo Program Buses (STA, STB, and STC) that are accessible
from channels and the six Stereo Returns. The output of each stereo Program Bus “Active Combining
Amplifier” (ACA) feeds its own Program Master. Each Program Master is equipped with an on/off switch,
balanced insert with switch, 100mm automated resistive Master Fader, output trim pots, associated
patch points, and assignment to the Grand Master.
A stereo Grand Master is provided for summing the A, B, and C Program Bus outputs and the outputs
of the Stereo Returns into a single master stereo program output. Like the Program Masters the Grand
Master is equipped with an on/off switch, balanced insert with switch, 100mm automated resistive
fader, output trim pots, and associated patch points, but also inputs for an external stereo source.
In combination, the three stereo program masters and stereo Grand Master provide a host of flexible
routing possibilities parallel processing, mix versions, segues, and other mixing techniques.
