In addition to using Auxiliary Sends and Returns to access outboard devices, the TM300
also provides channel inserts for channels 1 - 4. These should be used when you want
to affect just one input signal, as opposed to signal from several inputs—most often, this
will be for dynamic processing purposes (such as outboard equalization,
compression/limiting, or noise gating). You can also use the channel insert sends as
post-eq (but pre-fader) direct outputs, if you need to route a single monophonic signal to
an external device such as a tape deck.

The TM300 also provides two sets of main inserts—one "pre" graphic equalizer and
stereo fader, and the other "post" graphic equalizer and stereo fader. These allow you
to process the entire mix simultaneously (for example, "strapping" a stereo compressor
or gate across the mix) at unity gain.
All TM300 insert jacks (channel and main) accept 1/4" TRS plugs, with the ring carrying
the send signal and the tip carrying the return signal; this will normally be connected to a
Y-cord (see the "Connecting The TM300" section on page 10 in this manual for a wiring
diagram). This configuration is sometimes known as an "effects loop," since the signal is
sent and returned over the same cable.
If nothing is plugged into the main or channel insert jacks, they have no effect—but if you
connect them to a passive device like a patchbay, you'll need to normal (permanently
connect) or half-normal (connection is made unless overriden by a patch cord) the send
to the return. Note that channel insert signals are returned just before the channel
faders. For this reason, you'll have to be careful to set the output of connected external
devices to unity gain.
