Before suspending any speaker system 
always inspect all components (enclosure, 
rigging frames, track fittings, etc.) for cracks, 
deformations, corrosion, missing, loose or 
damaged parts that could reduce strength 
and safety of the array. Do not suspend the 
speaker system until the correct preparation 
of the installation site has been taken to avoid 
health risks during and after the completion 
of the installation. A licensed Professional 
Engineer must approve the placement and 
method of attachment to the structure prior to 
the installation of any overhead object.

Rotating the Horn Flare

The asymmetrical horn flare can be rotated 
through three separate planes of dispersion 
depending on the speaker box requirement 
and installation environment. The planes are 
vertical installation, horizontal installation and 
foldback monitor. 

Good coverage of audiences often requires 
wide dispersion at the base of the horn flare 
to cover close listeners and a focused narrow 
dispersion at the top of the flare to beam to 
the back of the room. 

The QM350i horizontal horn covers both 
“short-throw” and “long-throw” requirements 
in a single system. 

Flying the QM350i

For the majority of installations (where the 
box is installed vertically), the asymmetrical 
horn should be used as supplied and will not 
need to be rotated.

For horizontal installation rotate 45 degrees 
so the arrow is pointing at the floor side so 
as to have the “beaming” facility at the top of 
the horn.

Foldback HF coverage

For stage foldback monitors the coverage 
must be wide when performers are close 
to the wedge and beam down the stage 
to minimize the spill off the stage that may 
interfere with the main PA. 

For floor monitor use the horn must be 
rotated with its “wide” dispersion (arrow 
indicator), side directed towards  the top of 
the horizontal floor cabinet.

When removing and reinstalling the front grill 
to rotate the horn, ensure the nuts are not 
over tightened as this may make them difficult 
to remove in future or cause them to break. 

If damaged, the cage nuts can be replaced 
easily with standard rack mount cage nuts. 

WARNING

Ensure the box is securely located. If any doubt about the physical 

stability, tie the box down with ratchet straps to a secure base.
