1/4" Insert Jacks [Pr and Pr]
These unbalanced 1/4" jacks are for connecting serial effects processors such as compressors, equalizers, de-essers, or filters.
The insert point is after the gain control and low cut filter, but before the channel’s EQ and level. The channel signal can go out
of the insert jack to an external device, be processed and come back in on the same insert jack.
To do this requires a standard insert cable that must be wired thusly:
Tip = send (output to effects device)
Ring = return (input from effects device)
Sleeve = common ground
Insert jacks may be used as channel direct outputs; post-gain, and pre-EQ. If you insert a TS (mono) 1/4" plug only partially
(to the first click) into an insert jack, the plug will not activate the jack switch and will not open the insert loop in the circuit
(thereby allowing the channel signal to continue on its merry way through the mixer). This allows you to tap out the channel
signal without interrupting normal operation.
If you push the 1/4" TS plug in to the second click, you will open the jack switch and create a direct out, which does interrupt
the signal in that channel. See illustration below.
Do not overload or short-circuit the signal you are tapping from the mixer. That will affect the internal signal.
As seen in the pictures above, both the Pr and Pr have four 1/4" insert jacks (on channels 1-4).
There are no 1/4" insert jacks on the P.
