USER MANUAL MS20C ROLLS

MS20c 1/8" (3.5mm) jack

- The MS20c 1/8" (3.5mm) Input is a balanced TRS input. This Input, however, may be connected to an unbalanced signal source (Tip-Sleeve) such as a mixer output or line-level instrument output, and the MS20c balanced outputs connected to a snake or mixer's balanced input. NOTE: The Ring of the 1/8" jack MUST be connected to the Sleeve, and the bottom XLR Output jack will have it's pin 3 grounded.

- The 1/8" jack may also be used as an unbalanced output. Connect a balanced signal to the top XLR Input, the 1/8" jack may be connected via a Tip-Sleeve jack to an unbalanced input.

- By referring to the diagram on the top of the MS20c, you can identify the signal and grounding paths for all the jacks.
