the RimMount. Then push the body of the microphone from the bottom (XLR
connector end) to move the microphone up inside the rubber holder. The fit
will be firm, so you will need to apply a little pressure to move the microphone
body up into the rubber holder. The suggested procedure is indicated in Fig-
ure 3.

Mounting the RM1 RimMount to the Drum
The RM1 RimMount is designed for metal drum rims, and will not work on
wooden drum rims. While reading this section, please refer to Figure 4-A,
which shows the various elements of the RimMount™. Mounting the Rim-
Mount to the drum rim is quite easy. First, unscrew the thumbscrew so there
is more than enough space for the Delrin® cushioned rim-guide to clear the
bottom of the drum rim. Then determine where on the drum rim you want to
position the microphone and then place the top "hook portion" of the Rim-
Mount bracket over the drum rim. Referring to Figure 4-B, notice that on

the Delrin® cushioned rim-guide there are two sets of grooves. One set of
grooves is in the "center" of the rim-guide, while the other set of grooves
are "off center" (or closer to the edge of the rim-guide). These two sets of
grooves provide you with "three" mounting options: (1) using the "off center"
rim-guide grooves will place it closest to the drum shell, (2) or rotating the "off
center" grooves 180 degrees will place the rim-guide furtherest away from the
drum shell, and (3) the "center" grooves will allow placement in-between the
positions described in 1 and 2.

Figure 4-B Positioning the Cushioned Rim-guide
The various types of metal drum rims may have the bottom flange of the
rim either closer to the shell or further from the shell. Depending upon the
type of metal drum rim, one of the previously described three positions will
allow the RimMount bracket to be mounted parallel to the drum shell. The
soft protective Polyolefin® coating on the RimMount bracket will prevent the
possibility of scratching the drum shell finish. So position the rim-guide so
the bottom edge "flange" of the drum rim fits comfortably into one of the rim-
guide grooves. This will insure that the cushioned rim-guide remains securely
in place as you tighten the thumbscrew to firmly secure the RimMount to the
drum rim.
Adjusting the Microphone Height
Once the RimMount is mounted securely on the drum rim with the Drum Peri-
scope microphone housed in the rubber holder, the microphone body can be
moved either up or down in the rubber holder to provide the desired height.
Then the mini-gooseneck will provide a good amount of latitude in positioning
the microphone head from any pre-set microphone body height. Adjusting
the height of the Drum Periscope microphone body is shown in Figure 5-A
and 5-B.
