  • Page 16: Installation 1

    3. Installation 3.1 The Focus Modular Load-Bearing System Each Focus Modular module has two aluminium supporting tubes integrated into its enclosure. These are located behind the right and left side panels respectively, and can be accessed via openings in the aluminium covers that form the top and bottom ends of the enclosure. The two tubes carry the entire weight of the system – both must therefore always be used during installation! At the lower end of the supporting tube is a steel slider. This can be extended, enabling the Focus Modular module to be joined to another module. A knurled-head screw acts as a handle when moving the slider and also keeps the slider locked within the enclosure during transportation, or when the system is not in use.
  • Page 17 To connect the Focus Modular modules to one another, or to flying adapters, two ball lock pins are used. In the case of FMI modules, these are supplied loose, whereas with FM modules they are attached to the upper connector panel via safety cables. During transportation, these ball lock pins can be securely housed in two pilot holes on the connector panel. 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 WFM wall brackets.

    3.2 Assembling and dismantling a mobile Focus Modular system 3.2.1 General rules on assembly Number of individual modules The maximum number of modules in a Focus Modular stack is limited to six. VFM-1 flying adapter To safely fly one or more Focus Modular modules, a VFM-1 flying adapter is required. Using any other form of suspension is expressly forbidden! The VFM-1 has three suspension points for different purposes: (a) Drilled hole with 17 mm diameter, centre If one or more modules are attached here, the module(s) will hang vertically without any degree of tilt. In this instance, use the supplied 2000 kg shackle in accordance with DIN 13889. If other shackles are used, these must guarantee a Working Load Limit (WLL) of at least 2000 kg with an operating ratio (safety factor) of at least 6. The pin diameter of the shackle must be no less than 16 mm. If using (b) as an attachment point, (a) can then be used for a safety cable, provided that any potential outward swing of the module is also prevented in the event of a failure.
  • Page 19 (b) Drilled hole with 17 mm diameter, rear (b) can primarily be attached to elements that enable horizontal alignment of the Focus Modular system, if point (a) is being used for flying. If cables are being used for this purpose, the tensile direction should, ideally, be approximately horizontal, in order to prevent the modules from tilting. If (b) is used as an attachment point, a slight forward tilt of one or more modules can easily be achieved without the need for a second attachment point to be used.
  • Page 20 2. The VFM-1’s rear attachment point (b) can be used for mechanically tilting a Focus Modular system (see above). This enables a slight forward inclination of individual modules, or short stacks containing several Focus Modular modules, without using a second suspension point. For individual modules, the following inclination angles are possible from vertical: • FM-100: 14° inclination • FM-110: 9° inclination • FM-400: 8° inclination For stacks involving several modules, the following inclination angles are possible (the columns...
  • Page 21 Secondary safety cables The Focus Modular VFM-1 flying adapter is designed with an operating ratio of 10:1. However, despite all checks and worst-case scenario considerations, any component could fail during the flow of force between load and suspension point: This could either be a shackle or a motorized chain, or even the load bearing point in the ceiling itself. To guarantee the best possible degree of safety for staff, performers and public, we strongly recommend the use of safety cables or chains as a secondary safety component at all times – even in the kind of situation where it should not normally be required. This is even more important since Focus Modular has been designed as a “single-point-suspension” system. When selecting safety cables or chains, their load-bearing capacity must be such that they can resist the entire weight of the system (loudspeaker modules, flying adapter, cables, motors etc.) while complying with all local regulations. They should also be attached to a secure point that is structurally separate from the actual system suspension point.
  • Page 22 It is recommended that you do not use both of these points for flying a Focus Modular system, since this is virtually impossible without some lateral inclination occurring, which is forbidden.

    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 actually flown. Further information on allocating and changing ID numbers can be found in the “Fohhn-Net Cabling and ID Allocation” section (page 47), as well as in the Fohhn Audio Soft user manual. This can be downloaded free of charge from our website: www.fohhn.com It may also be helpful to put together a brief overview of all integrated Fohhn-Net devices, along with their respective ID numbers. 2.) Connect the top module to the VFM-1. Only use the ball lock pins which are located in their pilot holes in the connector panel. The VFM-1 must be slightly raised in order to do this. Make sure that both pins are fully inserted and that their collars are fastened to the metal of the supporting tube.
  • Page 24 To correctly secure the system, please pay careful attention to the “Secondary Safety Cables” section (page 21). 5.) Connect the system to its supply cables for power, network (Fohhn-Net) and audio signal. (For details on this, please refer to the “Cabling“, section on page 39.) “Ease” the cables to prevent them from dragging on the VFM-1.
  • Page 25 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. Then align both modules horizontally with one another. Stop the motor as soon as the chain loses its tension! Never put your hands in between the two modules!
  • Page 26 8.) Loosen the knurled-head screws on the upper module’s connecting bar and slide this into the lower module’s supporting tube. Keep the knurled-head screws loosened for the moment. 9.) Connect the two modules. Only use the ball lock pins which are located in their pilot holes in the connector panel. Make sure that both pins are fully inserted and that their collars are fastened to the metal of the supporting tube. The distance between the T-handle on the pin and the speaker enclosure should be no more than ca. 10 mm! 10.) Connect the lower module to its supply cables for power, network (Fohhn-Net) and audio signal. (For details on this, please refer to the “Cabling“, section on page 39.) Use the supplied cable set for connecting the modules.
  • Page 27 11.) Repeat steps 6 to 10 for each module in the stack. 12.) Hoist the completed Focus Modular system to its final working height. Fasten the safety bridle to the relevant points (see “Secondary Safety Cables” section on page 21). The VFM-1’s rear attachment point (b) can be used for horizontal alignment of the system (see above).
  • Page 28 13.) Dismantling the system is done in reverse order. Therefore, please observe the following: • Make sure that the surface onto which the system will be lowered can take the corresponding load, and is also level. • After the system has been lowered to the ground, the rigging motor must immediately be switched off! The chain should lose its tension, yet it must not be allowed to noticeably sag. Otherwise the system could tip over. • Never attempt to remove ball lock pins that are under load! This leads to risk of injury! •...

    3.2.3 Flying from traverses or bars Cardan Clamp CC-300 To safely fly either a single module, or a stack consisting of several Focus Modular modules from traverses or bars, round slings and safety chains can be used as described in the previous section – unless a CC-300 Cardan Clamp is available. Using a CC-300 has greater advantages with regard to ease of use and horizontal orientation. The CC-300 consists of three components: (a) Half Coupler The Half Coupler used here is a fixed system component, which should not be removed or substituted for other components that may appear identical in construction.

  • Page 31 3.) Connect the VFM-1 to the CC-300. This is done by pushing the CC-300’s Y-branch onto the VFM-1. The ball lock pin will then be fully inserted. The retaining ball must unlock without obstruction on the other side. This must only be done using the 10x50 ball lock pin that is fixed to the CC-300’s Y-branch. Loosen the rotation brake’s knurled-head screw. 4.) Lower the traverse from which the system is to be flown until the CC-300’s half coupler can be attached. Manually tighten the clamp in the first instance.
  • Page 32 5) Raise the traverse until the first module is hanging freely above the floor. The CC-300 will have now aligned itself vertically. Firmly tighten the nut on the half coupler and secure it with the lock nut. 6.) Fasten the safety bridle to the 1000 kg shackles, as necessary. If using separate cables or chains for both points, make sure that these are exactly the same length and that they are attached to the same point. To correctly secure the system, please pay careful attention to the “Secondary Safety Cables” section (page 21).

  • Page 37 3.2.4 Rain covers for mobile operation 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. In order to protect these electronics from moisture, a rain cover is essential if using a Focus Modular system out of doors. Never use a Focus Modular module in the rain without its original Fohhn® rain cover. Water ingress can cause danger to life through electric shock. The system itself can also be ruined. Only use original rain covers, otherwise the operational cooling process may be impaired. This can lead to the module overheating and shutting down. Fit the rain cover as follows: 1.) Guide both of the VFM-1’s mounting brackets through the slit in the lid of the rain cover. The fabric surface should now be facing upwards.
  • Page 38 3.) Join the lid to the sides of the cover using the zipper. The actual positioning of the rain cover on the loudspeaker enclosure is determined by the sewn-in magnets, which adhere to the front grille. Move the magnets and pull the cover tightly forwards and downwards simultaneously. 4.) Close the rain cover by pulling the zipper that runs the length of its side. The remaining opening above the connector panel will then be covered by the two flaps, which are pressed together and connected to the rain cover using Velcro strips. Keep these on the inside. Die verbleibende Öffnung oberhalb des Anschlussfelds wird danach mit den beiden Laschen abgedichtet, indem diese mit Klettband aufeinander gedrückt und mit dem Regenschutzdeckel verbunden werden. Halten Sie dazu von innen dagegen. 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. In order not to affect their functionality, never shut these openings and never press the rain cover flat against the loudspeaker.

  • Page 54: Side Lobe Free Technology 5

    4.1.1 Side Lobe Free Technology Due to their construction, line source and line-array speakers generate unwanted Side Lobes in their vertical axes. These result from the distances between the individual loudspeaker chassis and the finite length of an array. 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. Optimized beam with Fohhn Side Lobe Free Technology...

  • Page 55: Two Beam Technology (Two Beam Mode) 5

    4.1.2 Two Beam Technology (Two Beam Mode) Fohhn’s in-house developed Two Beam Technology enables the production of two independent beams with separately configurable parameters. In each case, the entire speaker line length is used for reproduction. So when activating the second beam, the sound dispersion still covers the entire frequency bandwidth. All parameters such as the vertical inclination angle and vertical beam width, the acoustic centre position, level and high pass filtering can be separately configured for each beam. This enables an asymmetric beam dispersion to be created for precise sound coverage of two separate listening areas (e.g. stalls and balcony).

Its depiction and management are covered in the following sections: The Device Selection This shows all the Focus-Series devices that are in the system, along with their IDs, names, type/model classifications and current operating status.
  • Page 58 The Device Selection (left), Focus Simulation (centre) and Parameter Field (right) Beam Steering settings in the Parameter Field: • X-Pos (m) This defines the distance of the selected speaker (in metres) in relation to the vertical back wall. • Z-Pos (m) Defines the height of the selected speaker’s lower edge (in metres) in relation to the floor. • Pre-Angle (°) Here you can enter the mechanical inclination of the loudspeaker. This value only influences the display in the Focus Simulation. • Freq. (Hz) Here you can input the reference frequency for calculation and display in the neighbouring Focus Simulation. The frequency you input here will have no effect whatsoever on the sound being reproduced by your loudspeaker! • Upside Down Adding a check mark to this field means that the loudspeaker effectively turns upside down. This can be useful if your Focus-Series loudspeakers have to be installed head first. • Beam 2 (previously: Split) Adding a check mark to this field creates a second beam for the loudspeaker in question. The following parameters can then be set for both beams, individually and independently from each other. • Angle (°) Here you can enter the beam’s vertical inclination angle – in 0.1° increments - within a range of +/-40°.

  • Page 61: Application Examples 6

    5. Application Examples The following examples show possible and useful combinations of the various Focus Modular modules in typical sound reinforcement scenarios. Individual parameter settings (e.g. vertical dispersion characteristics and inclination angles, acoustic centre etc.) are intentionally not shown here in detail. Level reductions are generally dependent on room depth, the opening angle of the beam and the room acoustic. Therefore, this information is only intended for rough guidance. For planning, use the Focus Simulation in the Beam Steering view. Here you can simulate the direct sound dispersion of a system.
  • Page 62 Example 1b: You can use the lower of two connected modules (in this case, the FM-100) in Two Beam mode and adjust one of those beams (Beam 2) to provide nearfield coverage. To align the level of the two modules, reduce the FM-100’s input level by ca. 8 dB. In the parameter field of the Beam Steering view, use the Trim parameter to separately reduce the level of Beam 2. For consistent behaviour of the limiter within the system as a whole, it is important that level adjustments are carried out on input (gain structure). 1b: 1 x FM-400 and 1 x FM-100 with a maximum room depth of 30 m. A second beam from the FM-100 covers the nearfield area.

  • Page 63: Larger Venues With A Single Audience Level 6

    5.2 Larger venues with a single audience level Example 2a: The venue has a room depth of more than 30 metres and a single audience level; here it is equipped with a “Combined Speaker“ (consisting of two FM-400s) and an FM-110. If a Focus Modular loudspeaker stack has several FM-400 modules, it must always be operated as a “Combined Speaker“! You can find more information on this in section 3.4.7 “Graphically arranging the loudspeaker systems” (page 51) of this manual. Due to the larger room size, an FM-110 module should be used for the high frequency range. To align the level of the two modules, reduce the FM-110’s input level by ca. 14 dB For consistent behaviour of the limiter within the system as a whole, it is important that level adjustments are carried out on input (gain structure).
  • Page 64 Example 2b: Depending on the application, it can make sense to use both the “Combined Speaker“ (with the linked FM-400 modules) and the FM-110 in Two Beam mode to achieve a more even coverage of the listening area. The same applies with rising audience seating. To align the levels of the modules, reduce the FM-110’s input level by ca 8 dB. In the parameter field of the Beam Steering view, use the Trim parameter to separately reduce the level of Beam 2. For consistent behaviour of the limiter within the system as a whole, it is important that level adjustments are carried out on input (gain structure). 2b: 2 x FM-400 and 1 x FM-110 with a room depth of more than 30 m and rising audience seating. A second beam from the FM-110 covers the nearfield area.
  • Page 65 Example 2c: In the following example, intended for venues with an even greater room depth (e.g. 50 metres or more), we have used at least two FM-400s as a “Combined Speaker“, in Two Beam mode, for the mid- and low-mid ranges, plus an FM-100 and an FM-110 for the high frequency range. For this more distant coverage, you can install an FM-110 above both FM-400 modules – with an FM- 100 at the bottom of the stack to cover the nearfield area. To align the levels of the modules, reduce the FM-100’s input level by ca. 10 dB and the FM-110’s by ca. 8 dB. In the parameter field of the Beam Steering view, use the Trim parameter to separately reduce the Beam 2 level of the “Combined Speaker“(consisting of the two FM-400s). For consistent behaviour of the limiter within the system as a whole, it is important that level adjustments are carried out on input (gain structure). 2c: 1x FM-110, 2 x FM-400 and 1 x FM-100 with a room depth of more than 50 m and rising audience seating.
  • Page 66 Focus Modular high frequency modules (FM-100 or FM-110) cannot be linked to form a “Combined Speaker“. They will be displayed as separate modules in the Beam Steering view. Always install the high frequency modules at the upper or lower end of a Focus Modular stack! Incorrect combinations: FM-400 above an FM-110 and FM-100 / FM-110 above an FM-100 and FM-400 (left) Correct combination: FM-110 above an FM-400 and FM-100 (right)

  • Page 67: Larger Venues With Two Audience Levels 6

    5.3 Larger venues with two audience levels Example 3a: The venue has a room depth of more than 30 metres and two audience levels – for example a theatre with stalls and a circle, or a town hall with stalls and a gallery; covered here by two FM-400s as a “Combined Speaker“ and an FM-110 installed below. Both the “Combined Speaker“ and the single FM-110 module are used in Two Beam mode. This provides each audience level with two completely independent beams, which can be adjusted to the acoustic conditions of the two levels. Moreover, one beam from the FM-110 can be directed, from below, onto the upper audience level.
  • Page 68 Example 3b: If an additional FM-100 module is available, you can install this at the lower end of the Focus Modular stack: The FM-100 is well suited to the lower audience area. Both high frequency modules can then be used without Two Beam mode. Each high frequency module covers one audience level respectively. To align the level of the modules, reduce the FM-100’s input level by ca. 10 dB and that of the FM- 110 by ca. 8 dB. In the parameter field of the Beam Steering view, use the Trim parameter to separately reduce the Beam 2 level of the “Combined Speaker“ (consisting of two FM-400s).
  • Page 69 Example 3c: If required, the FM-110 and FM-100 can be used in Two Beam mode and the beams directed accordingly: Here, the FM-110’s two beams only cover the upper audience level, while those of the FM-100 only cover the lower. The “Combined Speaker“, consisting of two FM-400s, covers both audience levels, each with one beam. To align the level of the modules, reduce the FM-100’s input level by ca. 10 dB and that of the FM- 110 by ca. 8 dB. In the parameter field of the Beam Steering view, use the Trim parameter to separately reduce the Beam 2 levels of all modules.

  • Page 70: Larger Venues With Three Or Four Audience Levels 7

    5.4 Larger venues with three or four audience levels Example 4a: The venue has a room depth of more than 30 metres and und several audience levels – for example, a theatre with stalls and several balconies; here, a “Combined Speaker“ is used, consisting of two FM-400s, along with a high frequency module (FM-100 or FM-110) at each end of the stack. By using the modules in Two Beam mode, different levels can be individually covered. To align the levels of the modules, reduce the input level of both FM-110s by ca. 8 dB. In the parameter field of the Beam Steering view, use the Trim parameter to separately reduce the Beam 2 levels of all modules.
  • Page 71 Example 4b: Depending on the size of the venue and the number of audience levels, it may be necessary to use more than two FM-400 modules in a “Combined Speaker“: A “Combined Speaker“ can consist of up to four FM-400 modules. To align the levels of the modules, reduce the input level of both FM-110s by ca. 6 dB. In the parameter field of the Beam Steering view, use the Trim parameter to separately reduce the Beam 2 levels of all modules.
