INTRODUCTION
CONFIGURING THE 1/4” INPUT JACKS AS DIRECT OUTS
Thank your for your purchase of the Rolls RM81 MIXMAX eight channel audio
mixer. 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.
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.
