4 FR-X range.
This user manual contains essential information for rigging and deploying FR-X elements to their full capability.
Carefully read this document in order to become familiar with the system.
Whether pole mounted or arrayed, the proprietary AUDIOFOCUS technology in the FR-X 12a and FR-X 15a cabinets make them
highly versatile units in your professional sound reinforcement inventory.
I. Physical features and hardware description
The FR-X range (constant curvature) features compact 2-way self-powered bass-reex enclosures loaded with neodymium
speakers and ferrite compression drivers coupled to a versatile AF horns. Operating over nominal frequencies from 50Hz to
20kHz, model dependant, the rotatable AF horn generates a 80°x30° asymmetric directivity pattern.
The FR-X rigging system allows assembling a horizontal or vertical array with constant curvature. Coupling between traditional
horns causes a lot of comb effects resulting in poor sound projection and coherence in the space due to bad coupling between
cabinets.
Thanks to the AF horn and specic DSP treatment, comb effects are eliminated to ensure a perfect coupling between FRX-a
cabinets and create a coherent wavefront at any location. We call that ‘’X-comb’’ technology that permits the use of rotating horn
to adapt directivity and curvature array.
Made of rst grade Baltic birch plywood, FR-X cabinets feature a 35mm standard bottom ange, standardised cargo ying
hardware and a specic H prole. Thanks to this and the proprietary horn technology FR-X can be pole mounted or own with
the H prole ensuring system stability and perfect coupling between cabinets.
