TRS Inserts
Some consoles use a single jack to perform both send and return functions.
In this case the jack would use tip‑ring‑sleeve (TRS) wiring, with one of the
signal wires performing the Send function, the other being used for the
Return. Both Send and Return share the common ground wire. For TRS
inserts, it is common to use a “Y” cable, one that has a TRS plug on one end
and then a split into two mono tip‑sleeve cables on the other.
Using a TRS insert, the effects device would have the insert Send cable
plugged into its Input and the insert Return cable plugged into its Output.
This wiring completes the signal loop without interrupting the audio being
played though the console.

Effect Device
Audio flows from the console insert point into the effect device and then
back to the console.
To use the AN‑16/i with this insert layout, both the In and Thru jacks on the
AN‑16/i are used. The main console’s Insert Send should be plugged into
the In jack on the AN‑16/i. The Thru jack on the AN‑16/i is used to return the
signal to the console, completing the audio loop. In this case the AN‑16/i acts
like an effects device, but it has no audible effect and does not change the
audio signal in any way.

Discreet Insert Send and Return Jacks
If a console uses separate jacks for Send and Return functions, the cable
connections are much more obvious. The Send from the Insert point on
the console is connected to the AN‑16/i In jack. The Thru on the AN‑16/i is
connected to the Return jack on the console to complete the loop. Both
balanced and unbalanced versions of this wiring exist on mixing consoles.
