OPERATION
CONFIGURING THE 1/4”INPUT JACKS AS DIRECT OUTPUTS
The eight 1/4”Input jacks come from the factory configured 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 RM83T lid.
For each channel there are dual three-pin headers with shorting jumper on two
pins. The setting from the factory is on “IN”. By moving the shorting jumpers to
the configuration shown as “OUT”(one jumper up, the other down), the jack then
becomes a Direct Output.

CONFIGURING THE 1/4”INPUT JACKS AS INSERTS
To configure a channel’s 1/4”jack as an Insert, first remove the RM83T lid and
locate the corresponding channel’s dual three-pin header. Move both shorting
jumpers down as shown below as “INSRT”, the jack then becomes an Insert.

CONFIGURING THE OUTPUT FOR MIC OR LINE LEVEL
The RM83T ships from the factory with the XLR Main Output configured as Line
Level (+4 dB). To change this to Mic Level (-10 dB), carefully remove the lid,
locate the Mic/Line header which is near the Main Output jack. Move the two
jumpers from the Line Level position (shown below on the right), to the Mic Level
position (shown on the left).
