Patching in Signal Processors
Input channels 1 and 2 feature INSERT I/O jacks. These make it easy to patch external signal
processors directly into these two channels. Typically, compressors, limiters, and noise gates
are used for this type of connection. Reverb, delay, and other effects processors can be used
The INSERT I/O connections, which use TRS (Tip, Ring, Sleeve) phone jacks, are two-way
connections, with the tip carrying the output signal from the MD8 to the external processor
and the ring carrying the output signal from the external processor back into the MD8. You
need special insert cables to do this. A wiring diagram for an insert cable is shown below.
Connect to MD8 INSERT I/O
The following illustration shows how to connect an external processor to the MD8's
INSERTs. Other equipment has been removed for clarity.
Once connected, operation is the same as normal. The signal source for the external proces-
sor 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 be assigned
to the groups, sent to the Stereo bus, or to the auxiliary sends.
