ISE 2013: Fohhn to showcase beam steering technology

German loudspeaker manufacturer Fohhn Audio will demonstrate the capabilities of its new beam steering products at ISE in Amsterdam (stand 7-H179).

The company’s Focus Series of electronically steerable line array systems will be on show, which includes the Linea Focus LFI-120 - LFI-450 family of 1.2m - 4.5m loudspeakers and the recently released Focus Modular series (pictured), comprising the FM/I-100 and FM/1-110 high frequency modules and the FM/I-400 low-mid/full range module. Fohhn will also premiere its new Linea LX-220 hybrid line source loudspeaker system.
 
The compact modules found in the Focus Modular range each contain three separate, specially developed DSP processors with dedicated functionality, designed to improve performance, and provide better dynamics and greater precision than standard steerable systems.

The FM/I-100 and FM/I-110 high frequency modules include eight/16 compression drivers (with Waveguide/horn system) and eight/16 multi-channel DSP amplifiers respectively, enabling maximum SPLs of 142 dB and 148 dB to be achieved at a one-metre distance. The FM/I-400 low-mid module includes 32 neodymium speakers and 16 DSP amplifiers with a max SPL of 139 dB/one metre. The systems can be combined and cascaded to meet various sound reinforcement requirements, while their slim design is tailored for integration into different architectural settings.
 
A feature of all Focus Series loudspeakers is Fohhn’s Two Beam Technology. This enables two separate beams to be generated from every loudspeaker, allowing simultaneous coverage of different areas using a minimal number of systems. Fohhn’s unique Side Lobe Free algorithm suppresses unwanted side lobes for more targeted coverage and better speech intelligibility, and the vertical beam width (0-90 degrees) and sound inclination angle (-40/+40 degrees) of every Focus loudspeaker can be fine-tuned in steps of 0.1 degrees.
 
Fohhn’s new Linea LX-220 hybrid line source system with two-way speaker technology is based on the design of the company’s LX-100 and LX-150 loudspeakers. The system was developed as a result of customer requests for a more powerful loudspeaker to cover larger room lengths of around 25 metres. The 2.2 metre system is equipped with 18 x 4” speakers and three 1” compression drivers with horn loaded Fohhn Waveguide system.
