In the manual we read:
I suppose this means we cannot use these jacks to use our external effect unit connected to MR as effect processors! Aren't I correct?INSERT I/O jacks 1 and 2
These phone-type unbalanced I/O jacks can be used to connect external effect units or another device for processing the audio signals already input to the MR816 CSX/MR816 X via the MIC/LINE/HI-Z jack (analog input jack 1) and MIC/LINE jack (analog input jack 2) respectively.
Further down it says:
Where can I buy such a cable?Connection to an INSERT I/O jack requires a special insertion cable as illustrated below.
Any help would be greatly appreciated.
