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 posi-

tions 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. 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 

Periscope microphone housed in the rubber holder, the microphone body 

can be moved either up or down in the rubber holder to adjust 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.

Positioning the Microphone Head

Once the Drum Periscope microphone height has been set, then the mi-

crophone head can be positioned where you desire. However, you should 

never place the microphone head “parallel” to the drumhead. The micro-

phone head should always be at “an angle” to the drumhead. This will 

prevent any possibility of the diaphragm being forced to the microphone

back plate which could cause an unwanted pop or thump in the sound 

or recording system. The flexible mini-gooseneck will allow you to move 

the microphone head either up or down above the drumhead as well as 

in and out from the drum rim.  In addition, you can change the angle of 

the microphone head for your desired results. Figure 6-A shows how the 

microphone head can be rotated while Figure 6-B shows how the micro-

phone head can be moved more toward the center of the drum by chang-

ing the positioning of the mini-gooseneck.

Plug in the LevelPad, if necessary

In close miking drums, one should keep in mind that the peak sound level 

at the microphone head is extremely loud. Microphones used for close 

miking  drums  should  have  a  sound  pressure  handling  capability  of  at 

least 140dB SPL with no audible distortion. The Drum Periscope™ micro-

phones will handle up to 145dB SPL without distortion. However, as men-

tioned earlier, with this kind of high sound pressure level, it is possible 

for the microphone output to be as much as +24dBV which may overload 

some microphone preamplifiers. The use of the Earthworks LevelPad in 

the microphone line will prevent any such distortion or overload. So, to be 

safe, we suggest that you first plug a LevelPad into the mic line feeding 

the Drum Periscope microphone. For full information refer to pages 3 and 

4 of this manual.  

Close Miking Snare Drums with the DP30/C

 

As previously mentioned, when close miking drums with a Drum Periscope™ 

microphone, never position the microphone head parallel to the drumhead.
