USING THE MIC EFFECTS INSERT

In order to add effects to the microphone signal, an insert cable is needed. The Tip of the 

plug acts as the Send, the Ring is the Return.

Connect the insert cable’s TRS end to the 

Mic FX Insert jack on the rear of the RM74. 

Connect the Tip connection to your effects 

processor’s Input jack, and the Ring connec-

tion to the Output of the effects processor. 

The RM75 effects insert is mono, so if the 

effects processor is stereo - choose a Mono 

output. You may need to refer to your effects processor owners manual for more informa-

tion about operating it in mono. 

Make sure a microphone is properly connected to the RM74 and the unit is on. Speak into 

the microphone and adjust the levels of your effects processor for the desired process and 

level of effect.
