– even in the most acoustically challenging venues. All the functions of a Focus Modular system can be controlled using a single piece of software, Fohhn Audio Soft. -
Page 6: General Safety Instructions
The information presented here should, however, be regarded as accompanying advice and it does not affect the ultimate responsibility of the user to ensure safe on-site operation of a Focus Modular system. -
Page 7: Electrical Safety Information
Contact details can be found in the appendix to this user manual. 1.1.3 Electrical Safety Information Focus Modular systems are Protection Class 1 appliances. They are built and certified in accordance with the VDE safety measures for electronic devices and, safety-wise, leave our factory in perfect condition. -
Page 8: Acoustic Safety Information
1.1.4 Acoustic Safety Information Focus Modular loudspeaker systems are capable of generating very high sound pressure levels, which can cause irreparable damage to hearing. Warning! To avoid potential hearing impairment, never stand in close proximity (5 metre or less) to a device while it is in operation. -
Page 9: Storage And Transportation
The temperature of the Focus Modular loudspeaker system will be displayed in Fohhn Audio Soft. Shutdown is getting more likely if the product is exposed to direct sunlight or very high environmental temperatures. -

3. Mechanical Setup and Rigging 3.1 Wall mount installation On the back of each Focus Modular module, two M8 threaded inserts can be found at both the top and bottom. These are solely intended for attaching dedicated wall brackets. 3.2 Rigging a Focus Modular System 3.2.1 Rigging System of a Focus Modular Module... -
Page 14: Flying Adapter Vfm-1, Number Of Arrayable Modules
To connect the Focus Modular modules to one another, or to flying adapters, two ball lock pins are used. During transportation, these ball lock pins can be securely housed in two pilot holes on the connector panel. Danger! Always make sure, no yellow tag is visible at the two latches and all ball lock pins are inserted correctly before hoisting the system. - Page 15 Focus Modular is a modular Beam Steering system. In its main mode of application, it is usually flown or suspended in a vertical, linear format. However, in some cases it can be advantageous – for acoustic or optical reasons – to carry out a mechanical inclination.

Page 17: Safety Chains
Never use just one of the safety chain suspension points of the VFM-1. Once the Focus Modular system has reached its final working height, all safety chains have to be pulled tight and attached to the safety suspension point as tight as possible. Any failure of a suspension element should only lead to a minimal drop in height, the maximum drop distance should be not more than 10 cm to keep the dynamic forces as low as possible. -

ID. To avoid any confusion during assembly, mark each module, e.g. with a sticker on its front grille that shows the Fohhn Net ID. This can be removed before the system is flown. It may be helpful to put together a brief overview of all integrated Fohhn Net devices, along with their respective ID numbers. - Page 19 Please refer to section 3.2.4. 5. Wire power cable, Airea data or Fohhn Net and digital audio data. Relief the cables to avoid them from dragging on the VFM-1.
- Page 20 6. Raise the currently suspended module to a height that enables you to position the next module directly underneath it. 7. Carefully lower the suspended module until it sits on top of the standing module. Stop the motor as soon as the chain loses its tension. Then align both modules horizontally with one another.
- Page 21 9. Connect the two modules. Only use the ball lock pins of the lower module located in their pilot holes in the connector panel. The knurled-head screws may now be tightened gently to avoid rattling noise of the Focus Modular system at high SPL. Danger! Make sure that both pins are fully inserted and that their collars are fastened to the metal of the supporting tube.
- Page 22 11. Repeat steps 6 to 10 for each module in the array. 12. Hoist the completed Focus Modular system to its final working height and fasten the safety bridle to the relevant points. Please refer to section 3.2.4. 13. Align Focus Modular system horizontally. Therefore, the VFM-1’s suspension point (b) may be used according to section 3.2.2.

Page 23: Flying From Traverses Or Bars
3.2.6 Flying from traverses or bars It is recommended to use the Cardan Clamp CC-300 when flying a Focus Modular system from traverses or bars. This gimbal suspension ensures that, under all operating conditions, no load bending can affect the connection between the traverse/bar and the Focus Modular system and that, even in the case of vertically slanting traverses, the system can hang unhindered in its centre of gravity. -
Page 24: Rain Covers For Outdoor Use
Every Focus Modular module is fully active, containing not only the Class-D amplifiers for the various drivers and the switching power supplies, but also all the necessary DSPs for signal processing. To protect these electronics from moisture, a rain cover is essential if using a Focus Modular system at outdoor applications. - Page 25 2. Connect the VFM-1 to the Focus Modular as described in section 3.2.5. The VFM-1 must be completely flush with the Focus Modular system’s rain cover to guarantee impermeability. Turn the rain cover lid’s protruding collar upwards. 3. Join the lid with the covers’ side elements using zippers. The actual positioning of the rain cover on the loudspeaker enclosure is determined by the sewn-in magnets, which adhere to the front grille.
- Page 26 5. The closed rain cover is kept away from the module’s rear panel by clamping elements. The two connector panels through which the Focus Modular system maintains its air supply and extraction are also equipped with clamping elements. Warning! Never shut these openings and never press the rain cover flat against the rear of the loudspeaker to avoid the system from overheating.

Page 40: Two Beam Technology (Two Beam Mode)
Beam with Side Lobes Focus Modular systems are equipped with Fohhn Side Lobe Free Technology: A specially developed algorithm effectively reduces the side lobes. This results in fewer unwanted sound reflections in the room. Consequently, levels of speech intelligibility are improved and feedback prevention is increased. - Page 41 This enables an asymmetric beam dispersion to be created for precise sound coverage of two separate listening areas (e.g. stalls and balcony). Two Beam Mode: The production of two separate beams Simultaneous sound coverage of stalls and balcony using two beams from a single Fohhn Focus-Series system Example of an asymmetric beam...
