====Auxiliary send routing====
The ''auxiliary send'' routes a split of the incoming signal to an auxiliary bus, which can then be routed to external devices. ''Auxiliary sends'' can either be pre-fader or post-fader, in that the level of a pre-fader send is set by the ''auxiliary send'' control, whereas post-fade sends depend on the position of the channel fader as well. ''Auxiliary sends'' can send the signal to an external processor such as a reverb, with the return signal routed through another channel or designated auxiliary return. Post-fader sends are normally used in this case. Pre-fade ''auxiliary sends'' can provide a monitor mix to musicians on stage (which they hear through [[Foldback (sound engineering)|monitor speakers]] pointing at the performers or in-ear monitors); this mix is thus independent of the main mix produced by the faders.

Most live radio broadcasting soundboards send audio through ''program'' channels. Most boards have 3-4 program channels, though some have more options.  When a given channel button is selected, the audio will be sent to that device or transmitter.  Program 1 is typically the on-air live feed, or what those listening to the broadcast will hear.  Other program channels may feed one or more computers used for editing or sound playback.  Another program channel may be used to send audio to the talent's headset if they are broadcasting from a remote area.
