HARDWARE SETUP Set Up HOW TO CONNECT AUDIO OUTPUT: There are three rear outputs as shown in the below diagram: MIXED OUTPUT is unbalanced audio output for MIC 1 & MIC 2 using 1/4” connection. When using this output, MIC 1 and MIC 2 have to share a signal. To produce different effects on each microphone, MIC 1 and MIC 2 need their own signals which can be done by using XLR connections. MIC 1 BALANCED OUTPUT is balanced audio output for MIC 1 using XLR connection.
