4.0: MIXER CHANNELS
The Ui mixers has a variety of input and output channel types. You can view all channels in the main 
MIX screen and drag-scrolling along the virtual console. You can also use the MIX page Slideout  
panels to select specic channel types and preset views.
INPUT CHANNEL - sections 4.1 and 4.2
A Ui Input channel consists of a GAIN section (physical input, pre-amp, phase, phantom power etc) and the 
MIX section. Input channels feed the main stereo bus (to the Master Channel), the aux send busses (to the Aux 
Master channels), and the FX send busses (and on to the FX Returns). An input channel’s contribution to these 
busses is controlled on the relevant software page, or in the channel’s EDIT screen.
AUX SENDS / AUX MASTER CHANNEL - section 4.3
Aux Outputs (short for Auxiliary) are the outputs on the top right of the Ui hardware. These outputs each have 
their own mix of input sources, separate from the master mix. Generally, aux outputs are used for musicians to 
hear their own mix on stage via a stage monitor speaker or to headphone ampliers for in-ear monitoring.  
Alternatively, the aux outputs can be sent to external hardware FX units.
SUB GROUP MASTER CHANNEL - section 4.5
If you want to have individual control over the drum kit mix components, for example, but also want single fader 
control over the whole kit’s contribution to the mix, you would use a Sub Group.
FX SENDS / FX RETURN CHANNEL - section 4.4
FX SENDS faders effectively determine the amount of effect on each input channel. They work much like aux 
sends in that a mix of input channel contributions is created on the FX SENDS page - one for each FX  
processor. 
MASTER CHANNEL - section 4.6
The Master Stereo Channel is the output channel for the main stereo (left & right) mix - determined by the input 
channel and FX Return channel faders and pan/balance controls.
