Patching In Signal Processors
Input channels 1 and 2 feature INSERT I/O jacks. These make is easy to patch external signal
processors directly into these two channels. Typically, compressors, limiters, and noise gates are
connected to this type of connection. Reverb, delay, and other effects processors can be used too.
The INSERT I/O connections, which use TRS (Tip, Ring, Sleeve) phone jacks, are two-way con-
nections, with the tip carrying the output signal from the MT8XII to the external processor and
the ring carrying the output signal from the external processor back into the MT8XII. You need
special insert cables to do this. A wiring diagram for an insert cable is shown below.
The following illustration shows how to connect an external processor to the MT8XII INSERTs.
Other equipment has been removed for clarity.
Once connected, operation is the same as normal. The signal source for the external processor
is taken after the channel’s EQ section. The output signal from the external processor is then
returned into the channel just before the fader. The processed signal can then be assigned to the
groups, sent to the Stereo bus, or to the auxiliary sends.
