Using Channel Inserts
In addition to using Auxiliary sends and returns to access outboard devices, the
PL 2404 also provides channel inserts for the first four input channels. 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-fade) direct
outputs, if you need to route a single monophonic signal to an external device
such as a tape deck.
The channel insert jacks on the rear panel 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 PL 2404” 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 channel insert jacks, they have no effect—but if you
connect them to a passive device like a patchbay, you’ll need to normal (perma-
nently connect) or half-normal (connection is made unless overriden by a patch
cord) the send to the return. The insert signal is returned just before the channel
Gain control. For this reason, you’ll have to be careful to set the output of exter-
nal devices connected this way to unity gain.
