Auxiliary Sends; Bus Sends - Yamaha AW2816 Manual

Auxiliary Sends

An auxiliary send (Aux Send) is a way to route the signal on the input channel to an output on
the mixer other than the main outputs. Auxiliary sends use a variable pot (potentiometer) to send
the signal to the auxiliary send outputs. Since variable pots are used it is possible to send as
much of each channel's signal out the individual auxiliary sends as desired. Auxiliary sends are
commonly used to route signal to external effects processors or for headphone mixes. In live
sound they are also used to create monitor mixes for the musicians on the stage.
The auxiliary sends can also be set to pre- or post-fader. Typically, an auxiliary send connected
to an effects processor would be set to pre-fader. For headphone mixes the auxiliary send would
be set to post-fader. By doing this the signal that is routed out the auxiliary send is not affected
by the level of the channel fader. This allows the engineer in the control room to adjust the
control room mix without affecting the headphones mix.
The AW2816 has six auxiliary sends. By default Aux Sends 5 and 6 are connected to the two
internal effects processors of the AW4416. The remaining Aux Sends can be used to route
signal to external effects devices or for headphone mixes.
On the AW2816, the Omni Outs are commonly used for Aux Sends but it is also possible to
install an analog output card (MY4DA) that can be used as Aux Send outputs.
Unlike a traditional mixer, which uses pots to adjust the auxiliary send levels, the AW2816 uses
the faders. When an AUX button is pressed in the Fader Mode section of the AW2816, the
faders become the auxiliary sends. For example, when the AUX 1 button is pressed the faders
are used to send the individual channel signals via Aux Send 1. If Fader 1 is raised then Channel
1 will be sent via Aux Send 1, if Fader 2 is raised then Channel 2 will be sent via Aux Send 2,
etc.
The auxiliary send levels for each individual channel can also be viewed and adjusted on the
Channel View Screen of the AW2816. Simply select the desired channel, press the VIEW
button, then the F1 button to view the Channel View screen.

Bus Sends

Like an auxiliary send a bus send is used to route the signal on the channel to a mixer output.
The difference is that a bus send does not use a variable pot. A bus send will send a fixed level to
the output. Bus sends are typically used to route an input channel to a track on the multi-track
recorder. They are also used to bounce tracks.
