Pull the MMC 2 out until you feel the slight resistance of the Cam/Stop. (Note- 
If you do not feel the resistance of the Cam/Stop, the Cam has been rotated 
180 degrees and the Cam must be rotated further until the Cam and Stop 
intersect.) Insert the long 5/64 inch allen wrench into the Cam/Stop at the 
bottom of the speaker as shown in Fig. 1 and 2 below and loosen the allen 
screw. Rotate the MMC 2 to the desired position as shown in Fig. 3 and 4 while 
holding the Cam/Stop stationary. It is necessary to raise the MMC 2 slightly to 
remove the weight of the speaker o

 of the Cam/Stop so that the speaker can 

be rotated independently of the Cam/Stop.Tighten the allen screw. If the Cam/
Stop moves in the process of moving the MMC 2, the angle will be wrong. In 
that case, another adjustment will be necessary.

 the speaker panel as high as possible to expose the allen screws. Insert the 

long 5/64 inch allen wrench into the allen screws in the Cam/Stop at the 
bottom of the speaker as shown in Fig. 1 and 2. Loosen all but one of the allen 
screws (Your cam may have 2 or 3 allen screws). Next, pull the MMC 2 out 
until you feel the slight resistance of the Cam/Stop. (Note- If you do not feel 
the resistance of the Cam/Stop, the Cam has been rotated 180 degrees and the 
Cam must be rotated further until the Cam and Stop intersect.) Maintain the 
speaker panel at the position where the Stop has hit the Cam. Li

 the speaker 

panel as high as possible to gain access to the allen screws. Insert the long 5/64 
inch allen wrench into one tightened allen scew in the Cam/Stop. Loosen the 
allen screw and 

use the allen wrench to hold the cam at the same position 

while you rotate the MMC 2 to the desired position. It is necessary to keep the 
weight of the speaker panel o

 of the Cam/Stop so that the speaker can be 

rotated independently of the Cam/Stop. Tighten the allen screw. Invariably, the 
Cam/Stop will move slightly in the process of moving the speaker panel and 
the angle will be wrong. In that case, another adjustment will be necessary. 

Th

last step is to check the panel angle by using the Controller/Power Supply 
which may not be the exactly the same as the manual setting. 

Th

e angle of the MMC 2 should never be set for less than 30 degrees for 

optimum sound.
