Attachment of the VFA-122 variable flying bracket 

 

Using  the supplied  M10  hex head  bolts, align the mounting  holes in the VFA 
bracket with the mounting points on the top or the bottom of the enclosure.  

Ensure  that  both  the  flat  and  locking  washers  are  used  –  the  flat  washer 

should be in contact with the cradle.  Tighten the bolts to ensure a solid fit. 

Finally, attach a hook-clamp  to the mounting point and  secure the mounting 

point bolt through the main section of the VFA-122 bracket.  

 

The VFA-122 bracket works on the centre of gravity  of the EMS-122.     The 

lone  hole in the centre of  the VFA bracket will mean the EMS-122 enclosure 

will hang level.  Moving the pickup point to the rear of the enclosure will add 
down-tilt, and moving to the front of the enclosure will apply up-tilt.  Each notch represents 5-degrees of angle, so 

by taking the weight of the loudspeaker the angle can easily be changed.  The VFA-122 will provide 25-degrees of 

angle in each direction.  For larger down-tilt angles, position the pivot on the last hole and use the point on the 

rear or underside as a pull-back. 

 

Ensure that an M8 eyebolt is secured to the rear point on the EMS-122 enclosure to use as a secondary safety. 

 

Assembly of clusters using the DFB-122 flyplate set 
Using the supplied M10 socket head bolts, bolt through the DFB-122 plate into 

the enclosures.  Ensure that both the flat and spring washers are used  – the 

flat washer should be in contact with the plate.  Once the desired angles of the 

loudspeakers are set, tighten the bolts to lock in place.  Then turn the cluster 

over and repeat the process on the bottom.  Use the rear points on the EMS-

122  enclosures,  or  the  M10  holes  on  the  DFB  plates  to  use  as  a  secondary 

safety.

 Installation Brackets 

It  is  strongly  suggested  that  you  position  your  loudspeakers,  then  mark  &  drill  the  holes  in  the  mounting  walls 
before  you  attach  the  bracket  to  the  loudspeaker,  as  it  is  much  easier  to  check  positioning  and  fit  of  the  holes 
without the weight of the loudspeaker.   

 

The  EMS-122/122w  is  designed  to  work  with  OmniMount

TM

  Series  60  or  PowerDrive

TM

  Series  100 

products.   

Lie the enclosure on its front and remove the four M8 countersunk points on the rear of the enclosure.  Position 

the loudspeaker-side of the bracket as required, reinstate the bolts and retighten.  The bracket and EMS-122 can 
now be mounted using the holes you have pre-drilled.
