To configure the Bosch LA3-VARI-CS

Description

System description Bosch VARI-Directional (linear Loudspeaker array) In many large modern and classical buildings, like passenger terminals and cathedrals, to cover floors, walls and ceilings used solid hourgeoisie materials. Due to their size and absence of absorbing materials the reverberation time will be quite large, and the ratio between reverberated reflected sound and the direct sound will be high. This adversely affects speech intelligibility. However, it is very important to hear and understand verbal messages, whether the message about the change of departure gate at the airport, prayer in Church or the message to evacuate in an emergency. A linear array with variable focus Vari-directional Bosch offers a really sensible and convenient solution.

Functions:

Improved management of directional characteristics, Linear array with variable focus Vari-directional Bosch provides a good ratio between the direct and reflected sound. First, the array radiates more direct sound towards the audience, and secondly, it causes less reflections from the ceiling. The increased direct sound is also due to the lower attenuation coefficient of sound level with distance from source compared with traditional loudspeaker designs, acting as a point source. Instead of a mechanical direction throughout the audio speakers on the audience, a linear array with variable focus Vari-directional Bosch can send a virtual array of loudspeakers by using e-settings. Electronics controls the loudspeakers of the array separately by using signals with different delay, move the virtual speakers. Due to this, the array can be positioned vertically on a wall or even built into the wall. From an aesthetic point of view it is more acceptable and, besides, reduces the number of distort incoherent reflections from walls. In addition, in a linear array with variable focus Vari-directional Bosch uses advanced technology to control the directional characteristics, which allows to achieve a shape of the main lobe of providing an equal level for all significant frequencies at all listening. Only then the students will get balanced sound. Another important factor is the volume of the signal which should be almost the same for all places of listening without "hot spots". To ensure a uniform level in a large room shape of the main lobe of the directional diagram should be optimized in accordance with the listening plane (ear level). To solve these problems it is necessary that each sound frequency in the range of interest level of each individual speaker were carefully controlled. A linear array with variable focus Vari-directional Bosch performs this combination by setting the frequency characteristics and the delay in the digital domain using a digital signal processor to subsequent multi-channel amplification. Further around the room in the plane listening can be achieved a constant level of SPL with minimal side lobes of the directivity. But the Bosch arrays are characterized by two additional ways. First, the array can operate with non-planar planes listening, such as in theaters and auditoriums. Secondly, HE NOT Only tries to maximize the direct output On the listening plane, but also to minimize the unwanted output in the region. Due to the physical limitations of the array of loudspeakers, each the actual array will have side lobes orientation. In the configuration of linear array with variable focus Vari-directional uses an advanced optimization algorithm which allows to minimize the strongest side lobes to provide the best coverage combined with a maximum ratio of direct to reflected sound.

Easy to install and configure:

A linear array with variable focus Vari-directional Bosch greatly simplifies the installation and configuration configuration for the installer and engineer sound. Most applications can be described in a fairly straightforward way, where the configuration can be selected from the database of optimized settings. The selection is done quickly and interactively by entering a few basic parameters of the room, the position of the array and the plane of the listening position. Next, the configuration utility produces a graphical display implemented by direct coating of the SPL. In a set of configuration Vari configuration Set includes the configuration and signal Converter USB to RS485 signal to the USB port of a PC to one or more devices Vari (networked), even for covering long distances. Using the optional CobraNet module also has the ability to customize and control several devices in an Ethernet network.

Modular principle:

The main design feature of a linear array is its length. To transmit sound over long distances the array must be long. If listeners are close to the array, the array can be short. Due to the fact that the array has a modular design, there are three different lengths of arrays: 1,20, or 2,40 3,60 m. the Array consists of at least a primary block and one or two expansion blocks. Each block has a length of only 1.20 m to facilitate transportation. The basic unit consists of controller, module, digital signal processing, power supply and 8 power amplifiers and loudspeakers. The expansion unit consists of 8 speakers with auxiliary output amplifiers. All necessary connections between the main and expansion unit are carried out automatically when devices are connected together by bolts with no visible connections. Power and signal cables being laid in main unit through the hole in the back of the unit to the inside compartment for connections, protected from unauthorized opening, to which you have access only during installation. Thanks to all-steel housing, grille and silver-grey powder coating line arrays with variable orientation Vari-directional Bosch blends perfectly with any modern and classical interior or exterior design. Due to the fact that the cooling surfaces, are also possible embedded installation. In the standard delivery kit of the device includes swivel bracket for wall installation.

The ability to connect via CobraNet:

A linear array with variable focus Vari-directional Bosch provides the possibility of equipping the main unit with a small CobraNet module that enables to connect the array to an Ethernet network using a cable connection CAT-5. Due to this alarm sound will be transmitted in an array in a digital format with low latency and a high degree of routing flexibility. In addition, it is possible to configure the array through the Ethernet network, as well as monitoring and recording its operation. The use of standard Ethernet cables reduces costs. CobraNet technology allows for simultaneous voice and data flow through the standard Ethernet infrastructure, providing a significant reduction in costs for design and installation. CobraNet is a technology owned by the company Cirrus Logic, which is used by many manufacturers of professional audio equipment as the preferred technology for transmission of digital audio over the network.

Emergency notification:

System of emergency warning and information systems are an integral part of modern life. They are required for many commercial establishments and places of public accommodation and must comply with special standards, such as IEC60849, BS5839-8 and EN54-16. System elements linear arrays with variable orientation Vari-directional Bosch was designed to account for compliance with these standards from the beginning. Thus, the array may be used not only for transmission of service messages or background music, and as an element of the warning system, for example in combination with the Bosch Praesideo systems, which are one of the most advanced warning systems, a huge number of which installed all over the world. For example, a linear array with variable focus Vari-directional equipped with a detection circuit a control signal at the input to control the audio connection, internal supervision of operation, connection for redundant power supply 24 V (battery), output the fault relay and fault logging from the network access. A linear array with variable focus Vari-directional Bosch is the ideal speaker system for the transmission of voice signals in the event of an emergency situation where you require a clear, legible and unambiguous declarations.

Automatic volume adjustment:

In certain places, such as stadiums and passenger stations, the background noise level is constantly changing. This can greatly affect the intelligibility of voice messages. A linear array with variable focus Vari-directional Bosch has a built-in sensor noise, which can be configured to control power amplifiers for constant adjustment of the volume level. Automatic volume control maintains a comfortable level of sound in accordance with the level of background noise for enhanced intelligibility without exceeding the required volume level.

Audio processing:

For large halls or platforms may need several arrays in different places. Sound output arrays must be installed in time to prevent the formation of an echo at the listening position. A linear array with variable focus Vari-directional Bosch has an integrated adjustable delay with high resolution. To configure the array in accordance with an acoustic environment, for example, to increase the limit before the occurrence of acoustic feedback is provided by 8-band parametric EQ. Dedicated 4-band EQ on the inputs provide a separate frequency response, for example for background music and announcements.
