2. The Product

2.1 Product Description

FOHHN® LINEA FOCUS loudspeakers are active, high performance line source systems that can be

remotely controlled and monitored. Equipped with coated 4” long excursion drivers, the systems

have integrated CLASS-D amplifiers and DSP technology specially developed for this area of application.

The main feature of these systems is their BEAM STEERING TECHNOLOGY. This enables intuitive

control of the systems’ vertical beam dispersion characteristics - in real time – using FOHHN AUDIO SOFT (Version 5.0.3 or later): the vertical beam width is adjustable from 0° and 90° and the vertical

inclination angle from -40° to +40°, in precise 0.1° increments. This helps to avoid unwanted reflections from floors and ceilings, while enabling precise, even coverage of audience areas. Conventional mechanical tilting, i.e. the physical adjustment of the loudspeaker at the venue, is no longer necessary.

The current version of FOHHN AUDIO SOFT can be downloaded free of charge from

www.fohhn.com .

If higher sound pressure levels are required in the low frequency range, LINEA FOCUS systems can easily be combined with FOHHN active or passive subwoofers.

LINEA FOCUS has been developed for both mobile and fixed installation applications. The models described in this manual are fixed installation variants, e.g. for use in churches and cathedrals, congress halls and exhibition centres, airports and railway stations, theatres, TV studios, university lecture theatres and auditoria, conference rooms or museums.

The following applies to all LINEA FOCUS models: The longer the line source system, the further its reach – and the better its ability to precisely control low frequencies.

Carefully place the grille in the groove at the base of the loudspeaker then lay it along the enclosure. Using both hands and equal pressure, press the grille carefully into its snap lock closure.

3.3 System Set-up

LINEA FOCUS loudspeaker systems have no on/off switches, however, connection to the mains

supply via the power cable makes them ready for immediate operation. To avoid any circuit overload when switching on, the systems are equipped with a switch-on delay (or Soft Start function).

Only connect the LINEA FOCUS systems to the main power supply AFTER all other system

components (mixing desk, playback devices, etc.) have been switched on.

Switch off in reverse order, disconnecting the systems from the mains power BEFORE

switching off all the other components! Otherwise this could result in hearing damage due to loud signals! Nobody should stand directly in front of the loudspeaker systems for any length of time!

3.3.1 Configuration

Using the FOHHN-NET network, you can remotely control and monitor the functionality of your LINEA FOCUS systems’ integrated digital signal processors (DSP). For this you will need a Windows PC with FOHHN AUDIO SOFT (Version 5.0.3 or later) installed.

Further information on FOHHN-NET and the use of media control systems can be found in the FOHHN-NET Technical Manual at www.fohhn.com under Downloads > Manuals > FOHHN-NET.

When connecting DLI-130/230 AES, DLI-130/230 ANA, LFI-350 and LFI-450 systems, you will need an appropriate FOHHN-NET Adapter: the NA-11 FOHHN-NET USB ADAPTER, or NA-3 FOHHN-NET

ETHERNET ADAPTER.

Example: Controlling a DLI-130 ANA system via computer and NA-11 FOHHN-NET USB ADAPTER

Connecting DLI-130/230 DAN product variants to the FOHHN-NET is done via an Ethernet Switch, to which an appropriate Dante device must also be connected. For control via PC, Audinate’s Dante

Controller software is required in addition to FOHHN AUDIO SOFT (see Chapter 3.3.4 “FOHHN-NET Cabling and ID Allocation“).

You can download the Dante Controller software free of charge from here:

https://www.audinate.com/products/software/dante-controller

Example: Control of three DLI-130 DAN systems via computer and Ethernet Switch for simpler cabling

Example: Control of three DLI-130 DAN systems via computer and Ethernet Switch using redundant cabling.

(Here, all devices must already be in “Redundant Mode”.)

With a DLI-130/230 DAN system, all Dante Input Interface parameters (e.g. the audio routing

inside a Dante network) must be configured using the Dante Controller software.

DLI-130/230 DAN Firmware Update

Updating the Dante Firmware in a DLI-130/230 DAN requires the Dante Firmware Update Manager software. You can download this free of charge from the following URL:

https://www.audinate.com/products/firmware-update-manager

Dante Firmware files have the extension .dnt and can be downloaded from here:

https://www.fohhn.net/download/dante/

Example: Focus_1.0.2.dnt for Dante devices in the FOCUS-SERIES.

Perform the update as follows:

1. Start the Dante Firmware Update Manager.

2. Select the appropriate network interface and confirm the selection with Next.

3. Select Update Dante Firmware.

4. Select the appropriate .dnt file and confirm the selection with Next.

5. Select the listed Dante devices that are to be updated and click on Start.

6. Following a full update, the Dante devices should be restarted by switching off and on.

The Dante Firmware update only updates the firmware of the integrated Dante module. The FOHHN device firmware is unaffected and must, if necessary, be separately updated!

Here you can find all of Audinate’s technical documentation relating to Dante:

always work with the same software and within the same user interface.

The current version of FOHHN AUDIO SOFT can be downloaded free of charge from

www.fohhn.com

If a new version becomes available, proceed as follows to install FOHHN AUDIO SOFT on your computer:

1. Download the latest version of FOHHN AUDIO SOFT to your computer.

2. Locate the Fohhn_Audio_Soft_X.X.X_Setup.exe file on your computer (X.X.X represents the respective version number).

3. Start the installation program by double-clicking on the file: Follow the on-screen instructions.

4. Click on Install to install the program on your computer. Also confirm in the User Account Control dialog if this appears.

5. Click on Finish to complete the installation.

The software is immediately ready for use following installation and can either be opened via the program symbol on the desktop, or via the Start > All Programs > Fohhn Audio AG > Fohhn Audio Soft path.

3.3.4 FOHHN-NET Cabling and ID Allocation

For the control of multiple LINEA FOCUS loudspeaker systems, each system in the FOHHN-NET must be allocated its own specific ID. Using this ID, each individual LINEA FOCUS system can be clearly identified and controlled from within FOHHN AUDIO SOFT.

All loudspeakers systems have a factory setting of ID 1. Duplicated IDs lead to ID conflict. In such a situation, it will no longer be possible to control

the systems concerned.

ID allocation for individual systems:

In order for an ID to be allocated, each LINEA FOCUS loudspeaker system must first be connected to FOHHN AUDIO SOFT.

Proceed as follows:

1. Connect the LINEA FOCUS system to the mains power.

2. Depending on the product variant, connect an appropriate adapter or converter to the

computer. With the DLI-130/230 AES, DLI-130/230 ANA, LFI-350 or LFI-450, you can use an NA-3 or NA- 11 FOHHN-NET adapter. The DLI-130/230 DAN requires an Ethernet Switch.

3. Link the adapter or Ethernet Switch to the loudspeaker system using the appropriate CAT-

i.e. fibre-optic cable.

4. Start FOHHN AUDIO SOFT. The selected FOHHN-NET adapter will automatically be

recognised. With the DLI-130/230 DAN, the Dante Input Interface will be directly recognised. As a FOHHN-NET Node, the IP Address of the Dante Input Interfaces will be displayed. This will automatically be found, but it can also be manually configured.

5. When FOHHN AUDIO SOFT opens, an automatic search starts that results in the listing of all

correctly connected LINEA FOCUS systems.

If a system is not shown, check all the connections and re-run the search. When doing so, please also note the ID search range.

Proceed as follows:

1. In the Devices menu, click on the Search Device/ Network Scan dialog.

2. If the system is not shown, check the mains power supply and/or the network cabling in your

system. Then repeat step 1.

If a LINEA FOCUS system is recognised, this appears with ID 1 (factory setting).

To change the ID directly in the Find Devices dialog, proceed as follows:

1. Click with the right mouse button on a loudspeaker system in the dialog’s list view.

2. In the context menu select Change Fohhn-Net ID.

3. In the dialog with the same name, enter a new ID for the LINEA FOCUS system. Make sure

that this ID is not already in use.

Confirm this entry by clicking Ok: The loudspeaker will now have a newly assigned ID.

You can also change the ID of a LINEA FOCUS system at any time while it is in use. To do this, the systems must be in the FOHHN-NET. Proceed as follows:

1. Open the Device List view, either via the View menu or via the corresponding button on the

Toolbar.

2. Click with the right mouse button on a loudspeaker system in the list display.

3. In the context menu select Change Fohhn-Net ID.

4. In the same dialog, give the LINEA FOCUS system a new ID.

5. Confirm this by clicking Ok: The loudspeaker will now have a newly assigned ID.

Further information on setting up a FOHHN-NET and on FOHHN-NET ID allocation can be found in Chapter 4.1 “Fohhn-Net Setup” of the FOHHN AUDIO SOFT user manual.

3.3.5 Identifying Connected Systems

LINEA FOCUS DLI-130 and DLI-230 product variants have a function display with a blue LED located

behind the front grille. You can let this LED flash in order to visually identify the system.

1. In FOHHN AUDIO SOFT, click on the Status button in the Devices view to reveal a window

with information on the FOHHN-NET status, the operating time and the temperature of the connected devices.

2. Here, click on the Sign button: The LED on the front of the selected system will begin to flash.

3. Deactivate the button once the system has been identified.

Using the Light button, you can switch off the blue LED on the front of the system as required.

Alternatively, you can carry out this identification process via the Speakers view:

1. Open the Speakers view and click with the right mouse button on the desired loudspeaker.

2. Click on Sign in the opened context menu: The selected system’s blue LED will begin to flash.

3. When you reset the selection for the system, the LED will revert to its normal mode.

3.3.6 Renaming Devices / Channels

For better identification within FOHHN AUDIO SOFT it is recommended that, in an installation involving several LINEA FOCUS products, the individual loudspeakers are given separate names. Proceed as follows:

1. Open the Device List or Devices view, either via the corresponding entry in the Menu view or

via the respective button on the Toolbar.

2. Click with the right mouse button on the required system in the list (Device List), or in the

work space (Devices).

3. In the context menu, select the Rename Device option.

4. Enter a new name for the device in the Edit name dialog then close this by clicking OK.

The new name will now appear in the Device List, Devices and Channels views.

3.3.7 Graphically Arranging the Loudspeaker Systems

To make the FOHHN AUDIO SOFT display easier to manage, all the loudspeakers and devices in use can be graphically arranged on the software interface as desired. With complex applications and/or in the case of fixed installations, it is recommended that the arrangement of devices on the user interface corresponds with their physical positions in the room.

The name shown in the loudspeaker pictogram refers to the currently loaded loudspeaker preset. If a question mark is shown here, the loading process is not yet completed and the loudspeaker preset is not active!

Example: LINEA FOCUS system pictograms in Fohhn Audio Soft

(before completion of the loading process)

Proceed as follows to arrange your LINEA FOCUS systems:

1. Open the Devices or Speakers view, either via the corresponding entry in the Menu view or

via the respective button on the Toolbar.

2. Arrange the individual loudspeaker pictograms and/or devices according to the physical

positions of the actual loudspeaker systems and/or devices.

The arrangement will be saved in FOHHN AUDIO SOFT and will remain until you change the configuration or arrangement.

3.3.8 Loading Loudspeaker Presets

FOHHN AUDIO SOFT enables factory-made presets to be loaded into a LINEA FOCUS System.

To load loudspeaker presets, proceed as follows:

1. Select the appropriate LINEA FOCUS system in the Output Channels view.

2. Click with the right mouse button on the selected system to open the context menu.

3. In here, choose either Select speaker preset from list or Select speaker preset from database.

4. Select a preset from one of these lists.

5. Confirm your choice by clicking Ok.

Your loudspeaker preset is now loaded. Repeat the process for all LINEA FOCUS systems.

For DLI-130 and DLI-230 systems, three different loudspeaker presets can be selected from the database: Default, Music (for better music reproduction) and Speech (for improved speech reproduction).

DLI-130 or DLI-230 loudspeaker presets from the database

3.4 Further Options

3.4.1 Auto Power Save

LINEA FOCUS DLI-130 and DLI-230 systems have a configurable Auto Power Save mode, which

enables energy to be saved and the longevity of the device to be extended. If no audio signal is received, the integrated CLASS-D amplifiers switch to power saving mode. As soon as an audio signal is detected, the amplifiers are immediately ready for operation. The amount of time before the device switches to Auto Power Save can be set as desired – between 1 second and 12 hours. The mode can also be completely deactivated.

Proceed as follows to set up Auto Power Save in FOHHN AUDIO SOFT:

1. Select one or more LINEA FOCUS system(s) in the Device List, then with a right mouse click

open the context menu.

2. In here, select the Options entry. This will open the Advanced device settings configuration

dialog.

4. Select the entry Set pilot tone config. This will open the Set error on pilot tone fault window.

(You can also open this window via the corresponding button at the bottom left of the Advanced device settings dialog.)

5. Click in the Error on pilot tone fault box (bottom left) to add a check mark and confirm this

setting by clicking OK.

Pilot tone detection - LFI-350 and LFI-450 systems

In the case of LINEA FOCUS LFI-350 and LFI-450 loudspeaker systems, the analogue Input 2 is equipped with a priority circuit and pilot tone recognition.

An input level of > -30 dBV means that the signal will be exclusively transmitted via Input 2. An input level of < -30 dBV means that the signal will be transmitted via Input 1. From Firmware 2.12.10, the pilot tone keeps Input 2 active.

If the pilot tone and audio signal are switched off, the LFI defaults to Input 1 and will only transmit the signal via this input.

The pilot tone can also be activated in FOHHN AUDIO SOFT. If the pilot tone is missing, the LFI system sends a message via the fault message contact.

Pilot tone frequency: 20 kHz, > -30 dBV

Input 2 is also equipped with a low pass filter, operational at 16 kHz / -6 dB, in order to filter the pilot tone.

Using Input 2 without the pilot tone is not recommended as this can lead to fluctuations in level.

3.4.3 Switching Contacts

DLI-130/230 AES and DLI-130/230 ANA product variants have a contact input that enables loudspeaker system preset changes to be triggered via an open/close contact, (see Chapter 3.2.1

“DLI-130 and DLI-230 Connections“).

This switching contact can be configured in FOHHN AUDIO SOFT:

1. Select one or more LINEA FOCUS system(s) in the Device List, then with a right mouse click

open the context menu.

2. In here, select the Options entry. This will open the Advanced device settings configuration

dialog.

3. In here, select one or more LINEA FOCUS system(s), then with a right mouse click open a

further context menu.

4. Select the entry Set switch config. This will open the Input contact configuration window.

5. Select a setting from both drop-down lists for the “close” (Switch 1 close) and “open” (Switch

1 open) status: for example, you can deactivate the current status (Disabled) or load one of up to 100 presets (Load Preset).

6. Confirm your selection by clicking OK.

When the loudspeaker is switched on, the selected presets will be loaded according to the current “close” or “open” status of the switching contact.

Before configuring the switching contacts, we recommend that you first save all user presets.

Further information on saving user presets can be found in the FOHHN AUDIO SOFT user manual. You can download this from the Fohhn website: www.fohhn.com

3.4.4 Password Lock

LINEA FOCUS DLI-130 and DLI-230 loudspeaker systems (and their parameter settings) can be

password protected (or locked) to prevent any inadvertent changes. This password protection can be set up in FOHHN AUDIO SOFT.

Further information on password protection can be found in Chapter 6.6 “Password Lock” of the FOHHN AUDIO SOFT user manual. You can download this from the Fohhn website:

www.fohhn.com

3.4.5 Tilt Sensor

DLI-130 and DLI-230 systems have a tilt sensor whose data can be read out in FOHHN AUDIO SOFT.

This lets you determine the actual mechanical tilt of the installed loudspeaker systems. Please note that the tilt sensor has a tolerance of ± 1.0°.

Simply open the Beam Steering view and click on the READ button to the right of the parameter area.

The displayed sensor data can be updated by clicking on the READ button again.

You can transfer these determined tilt values into the Focus Simulation: Simply enter the value in the Pre-Angle [°] parameter field below.

4.1 Beam Steering – the functional principle

In the audio processing world, the term “Beam Steering“ refers to the process of controlling the beam dispersion characteristics of loudspeaker systems using electronics and software. Through specific manipulation of signal sources that are tightly positioned in close proximity to one another, it is possible to precisely control the vertical beam width and inclination angle of the loudspeaker system over a wide frequency range. In general: the longer the loudspeaker, the lower the frequencies that can be included in the “bundle”. Because each speaker driver can be individually controlled and adjusted, via use of a dedicated algorithm or DSP, this in turn influences the sound dispersion capability of the entire loudspeaker.

Graphic representation of a beam in the FOHHN AUDIO SOFT Focus Simulation

All FOHHN FOCUS-SERIES loudspeaker systems work with Beam Steering Technology.

Combining the DSPs with FOHHN AUDIO SOFT makes it possible to electronically control the loudspeaker system’s vertical inclination angle and vertical beam width – in real time!

FOHHN AUDIO SOFT enables the entire audio system to be configured in advance, before the systems themselves are put into operation at the venue.

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

LINEA FOCUS 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

4.1.2 Two Beam Technology (Two Beam-Modus)

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).

Two Beam Mode: The production of two separate beams

Example of an asymmetric beam

Further information on beam configuration and its associated parameters can be found in section

4.7.3 “System Setup (FOCUS-SERIES)” of the FOHHN AUDIO SOFT user manual.

4.1.3 Acoustic Centre

This function allows you to move the vertical position of a beam’s acoustic centre over the loudspeaker’s entire line length.

Acoustic centre at the top

Acoustic centre at the bottom

Further information on setting the acoustic centre can be found in section 4.7.3 “System Setup

(FOCUS-SERIES)“ of the FOHHN AUDIO SOFT user manual.

4.2 Setup in the Beam Steering View

To adjust your LINEA FOCUS system to the venue and the particular application, open the Beam Steering view in FOHHN AUDIO SOFT: This display lets you set all the parameters that are relevant to

Beam Steering.

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 FOHHN-NET IDs, names, type/model classifications and current operating status.

The Parameter Field

This lets you configure the beam dispersion characteristics of the chosen module in the Device Selection.

The Focus Simulation

This shows a graphic representation of your selected module’s beam dispersion characteristics,

based on the settings made in the Parameter Field.

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°.

 Beam (°)

Adding a check mark to this field lets you set the vertical width of the beam – in 0.1° increments - within a range of +/-90°.

 High-pass (Hz)

Adding a check mark to this field lets you enter the frequency threshold (10 Hz to 10 kHz): The fundamental tone below this frequency will be attenuated by24 dB / Octave (fourth order). The high-pass is recommended for effective masking of the fundamental tone.

 Side Lobes > Optimize

When adding a check mark to this field, Side lobes will be removed, as far as is possible, by means of a dedicated FOHHN algorithm. Because this makes the room less “excited”, levels of speech intelligibility will be significantly improved. With the overall volume level of the system now somewhat lower as a result, you can use the volume control in FOHHN AUDIO SOFT to compensate for this.

 Center (%)

When Optimize is active, you can change the acoustic centre of the loudspeaker. 0 % means that the acoustic centre moves to what is virtually the bottom end of the speaker, whereas 100 % takes it to the top end. In its default setting of 50 % (or if Optimize is not active) the acoustic centre sits at what is basically the optical centre of the speaker.

 Trim (dB)

Here you can attenuate the level of the selected beam over a range of 0 to -90 dB. If two beams are active, you can use these fields to set the relative levels of both in parallel.

Detailed descriptions of the individual fields can be found in section 4.7.3 “System Setup (FocusSeries)“ of the FOHHN AUDIO SOFT user manual.

4.3 Adjustment of DSP Functions

In addition to configuring the vertical beam dispersion characteristics of your LINEA FOCUS systems, FOHHN AUDIO SOFT also give you direct access to the parameters of the FOHHN AUDIO DSP (digital signal processor).

The following DSP functions are available:

 Input level  Output level  Routing  Delay  High-pass- and Low-pass filter  Equalizer  Dynamics  Signal Generator

Further information on the individual functions can be found in section 4.5 “DSP Functions“ of the FOHHN AUDIO SOFT user manual.

6. Troubleshooting

The following table describes how you can determine errors and shows the corrective measures that are recommended.

Problem

Possible Cause

Possible Remedy

No sound can be heard. However, there is an audio signal.

The in- and output routing in the User DSP is not correct.

Check the DSP Settings in FOHHN AUDIO SOFT.

The loudspeaker system is not recognised by FOHHN AUDIO SOFT.

Several products may have the same FOHHN-NET ID. (An ID conflict will be displayed in FOHHN AUDIO SOFT.)

Change the ID – no ID can appear twice (see 3.3.4

“Fohhn-Net Cabling and ID Allocation“).

The ID search range is restricted.

Extend the search range from ID 1 to 254.

The FOHHN-NET plug (see 3.2 “Cabling“) is not inserted.

Depending on the product variant, connect the system to either the NA-3 or NA-11, or to an Ethernet Switch (DLI-130/230 DAN).

The power, send and receive LEDS are not lighting up.

(Not applicable to DLI-130/230 DAN products!)

There is no supply voltage.

Check whether a supply voltage is present.

230 V not available, or fuse tripped.

Measure the supply voltage at the socket, check the fuse.

The send and receive LEDs are not lighting up.

(Not applicable to DLI-130/230 DAN products!)

The cable for the FOHHN-NET connection (see 3.2 “Cabling“) is defective or not plugged in.

Check the cable or connect the system to the NA-3 or NA-11. The power LED flashes alternate red and green.

There is a hardware error.

Contact the Service department at FOHHN AUDIO AG immediately.

If your problem does not appear in the above table, or if it is not fixed after trying the suggested remedies, please contact us at the following address:

7. Service and Repair

Servicing and/or repairs should only be undertaken by suitably qualified, FOHHN-trained personnel.

Do not carry out any servicing or any repairs to the device beyond what is listed in the “Maintenance Measures” section below.

For details of a FOHHN Service provider in your area, please contact us at the address on the previous page.

Keep the packaging for your device so that, in the event of any problem occurring, it can be returned in its original packaging. This will minimize the risk of any potential damage during transportation.

7.1 Maintenance Measures

 To clean your LINEA FOCUS system, only use a dry or slightly damp, well wrung out cloth.  Do not use any aggressive cleaning agents, waxes or solvents (such as cleansing alcohol or

paint thinner), as these could spoil the appearance of the device and/or affect the paintwork on the enclosure.

 There are no user-serviceable parts within the device.  The device must only be repaired by suitably qualified personnel.

8. Glossary

Term

Explanation

Beam dispersion

Here, this refers to the directional characteristics of a loudspeaker: Beam dispersion describes the spread of the acoustic waves originating from a loudspeaker (with regard to a particular frequency). The vertical beam dispersion of your LINEA FOCUS system can be adjusted electronically and in real time.

Acoustic centre

The acoustic centre of the beam can be moved along the full line length – electronically and in real time.

Beam Steering

The term Beam Steering denotes the control of loudspeaker system beam dispersion via electronics and software. Through the precise superimposition of closely positioned sound sources, it is possible to

“bundle” the sound over a wide frequency and flexibly adjust a loudspeaker’s beam dispersion angle.

More on this in section 4.1 “Beam Steering – the Functional Principle“.

DSP (Digital Signal Processor)

A DSP serves to process and control digitalized audio signals. Every LINEA FOCUS system has three different areas of DSP functionality (User DSP, Speaker DSP und Beam Control DSP).

FOHHN-NET

Here, this refers to a control network that is based on the RS-485 protocol.

More on this in section 3.4.4 “Fohhn-Net Cabling and ID Allocation“.

FOHHN-NET Adapter

To communicate with the LINEA FOCUS systems, FOHHN AUDIO SOFT requires an adapter for the FOHHN-NET, which is connected to the control computer and transmits the data generated in FOHHN AUDIO SOFT to the systems – e.g. an NA-3 or NA-11.

More on this in section 3.4.1 “Configuration“.

ID (FOHHN-NET)

Here, this refers to the assigned address of an active Fohhn device in the

FOHHN-NET. More on this in section 3.4.4 “Fohhn-Net Cabling and ID Allocation“.

Side Lobes

Due to their construction, line arrays generate unwanted Side Lobes. These result from the finite distances between the individual loudspeaker chassis and the length of an array.

Side Lobe Free Technology

A specially developed algorithm suppresses the Side Lobes. As a result, relatively little reverberation is generated, as less acoustic energy is dispersed in unwanted directions.

Two Beam Mode

See “Two Beam Technology“

Two Beam Technology

Every LINEA FOCUS System can generate two separate, completely independent acoustic beams over its entire line length. All parameters can be separately and individually set for each beam.
