The RM81 is a microphone and line mixer in a single 19" rack space. It is intended for sound reinforcement or studio applications where several microphones or line sources need to be combined to a single output. Please review this manual for proper operation. ROLLS CORPORATION 5968 South 350 West Salt Lake City, Utah 84107 Title Size: R O L L S M IX M A X 8 RM 81 The eight 1/4" jacks come from the factory as line inputs and are electrically mixed with the XLR jacks. They may be used together if desired. To configure a channel's 1/4" jack as a Direct Out, first remove the RM81 lid. For each channel there is a three-pin header with a shorting jumper on two pins. The setting is on "IN". By moving the shorting jumper to the other side labeled "OUT", the jack then becomes a Direct Output. Document Number: RM81.SCH Rev: D Rc Date: 18-Jun-1999 Sheet: 1 of 1
