DIAGRAM IIl-2.
Stage Location of the MM 12 for
Dedicated Monitor Mix Operator
1. Run a short snake from a stage box to the inputs of the MM 12; this snake
need only be long enough to reach from center stage to the MM 12 location,
but is is wise to make it long enough to run it along the edge of the stage out of
the way—a 25 foot length would be a minimum. This snake should have the
same number of pairs (inputs) as the main snake, with all lines BALANCED.
2. Connect the main snake into the system in one of the two following ways. To
keep the total numbers of cables and connectors to a minimum, modify the
main snake in the following manner:
a. Unsolder the main snake cable from the connectors inside the
stage box: be sure to label each of the shielded pairs as to which
channel it belongs and which colors are connected to which pins.
b. Remove the snake cable from the stage box entirely; you might
want to use the stage box for the short snake described in #l
above.
c . Strip about 18” of the outer sleeve insulation from the end of the
snake cable. Separate each set of shielded pairs and install about
17” of heat shrink tubing over each pair, so that you have 12 or 16
shielded lines emerging from the snake end. Securely tape the
area where the outer sleeve ends and all the heat-shrinked lines
converge.
d. Now solder a male three-pin connector to each of the shielded
pairs, making sure that the colors match the proper pins and
channels are numbered as recorded in Step a.) above. Now you
can plug the end of the main snake directly into the PATCH
OUTPUTS of the MM 12.
if you do not want to modify the main snake, make up to 12 or 16 cables using
shielded two-conductor mike cable and a male three-pin connector on one
end and a female three-pin on the other end. Use these to connect the stage
box of the main snake to the PATCH OUTPUTS of the MM 12.
3. If you are running more than 12 channels through the main board, bypass
the MM 12 with the channels that need not be in the monitor system, such as
guitars or bass which have their own instrument amps on stage.
4. Connect the OUTPUTS of the MM 12 to the inputs of the monitor
amplifiers—balanced lines are recommended if this run is more than six feet or
so.
