DVA K5 Code 420120232 REV.1.1 English Thank you for purchasing a product designed and developed in Italy by dBTechnologies! This 3-way active line-array module is the result of years of experience and innovation on speakers, with the use of cutting-edge solutions in the eld of acoustics, electronics and research on materials.

1. GENERAL INFORMATION

WELCOME! PRELIMINARY OVERVIEW The DVA K5 active line-array module is a 3-way speaker designed by building upon the innovation and professional quality of the DVA series. The 2 1” compression drivers (voice coil: 1.4”), 1 6.5” mid-range (voice coil: 2”), 1 8” woofer (voice coil: 2.5”) are housed in a polypropylene cabinet, reinforced by a metal frame optimising its sound performance. The DSP, controlling the next-generation amplier DIGIPRO G3, allows to easily and accurately congure the line-array sound behaviour according to: number of modules, angles of installation between the K5 modules, distance between line-array and audience. When coupled with the new DVA KS series subwoofers, nally, the module can meet all professional needs, in any context and installation. The main features of K5 are:

• powerful and noiseless amplication section , thanks to the new DIGIPRO G3 D-class amplier, requiring no active ventilation

• SPL (peak) of 129 dB

• high-quality transducers, sound design optimised for line-array use, full-range frequency response for professional use

• equipped as standard with pins and built-in brackets, pre-drilled and graduated, for easy, accurate and ready assembly/disassembly in a line-array conguration

• quick and accurate DSP conguration through 2 rotary encoders, optimising coupling and high frequency compensation

• Easy to handle and transport

• Lightweight, thanks to the polypropylene box and to the use of neodymium magnet components. USER REFERENCES To get the most from your DVA K5 we recommend that you:

MECHANICAL AND ACOUSTIC CHARACTERISTICS

DIMENSIONS DVA K5 only weighs 14.7 kg (32,41 lbs), and thanks to its small dimensions - 580 x 240 x 327 mm - it can be handled and transported easily. The reinforced polypropylene cabinet has a metal inner frame, preventing unwanted resonances and vibrations. The built-in brackets and the standard pins are ready to use and allow to quickly install, in the proper arrangement, a line-array having the desired characteristics. The acoustic coverage, for reference purposes, of a single module, as shown in the gure, is of 100 x 15°. The actual coverage depends on the use of multiple modules in a line- array arrangement. We recommend that you design it with the help of the free software dBTechnologies Composer.

The software dBTechnologies Composer, which can be downloaded for free from www.dbtechnologies.com, is a tool allowing users to properly design their audio system, recommended for all the equipment belonging to the DVA K series. It proposes the optimum solution for the selected areas, specifying the line- array module angle required to obtain the proposed coverage. It also allows to effectively check the safe installation of the line-array modules, by simulating the static behaviour of the y-bars. For further information please refer to the DOWNLOADS section of www.dbtechnologies.com.35 DVA K5 Code 420120232 REV.1.1 English

INSTALLING DVA K5 IN A LINE-ARRAY CONFIGURATION After dening the nal line-array characteristics, and the required angle in particular, you can proceed with the installation. Please check that Audio Input Sensitivity is set on 0 dB (common usage).36 DVA K5 Code 420120232 REV.1.1 English ATTENTION!

• Connect the rst module power supply to AUTO-RANGE MAINS INPUT (7). For this purpose, use a cable equipped with a powerCON connector (not included in the supply).

• Extend the power supply from the rst to the second module, by connecting the MAINS LINK OUTPUT (8) to the AUTO-RANGE MAINS INPUT (7), as shown in the gure.

• Repeat the operation between the second and the third module, and so on, until all line-array modules are connected (check the maximum number of power supply links in Technical Specications).

• The amplier nameplate of a DVA K5 module species the nominal maximum and total current (and power) value of a multiple module system with extension connections.

• The cables must be properly sized and design, installation and system testing should exclusively be performed by qualied personnel. AEB Industriale accepts no responsibility in case of use of cables which are unsuitable, non-certied, non-compatible with the correct system sizing and the regulations in force in the country of use.37 DVA K5 Code 420120232 REV.1.1 English

• Only use cables equipped with Neutrik® connectors

• Replace any damaged cables, to avoid malfunctions and poor sound quality.

• Connect the cable from MIXER/LINE to the BALANCED AUDIO (1) input of the rst line array module. For this purpose, use a cable equipped with an XLR connector (not included in the supply). For further information about the cables that are available please refer to the picture at p. 37.

• Extend the signal between the rst and the second module. To this purpose connect the OUTPUT/LINK (2) output to the BALANCED AUDIO (1) input of the second module.

• Repeat the operation between the second and the third module, and so on, until all line-array modules are connected.

• E - 9 to 10 speakers

• F - 11 to 12 speakers

• G - 13 speakers and beyond The use of a line-array provides multiple benets in various contexts; in particular:

• Homogeneous SPL along the speaker front direction; the effect is particularly noticeable over medium to long distances

• directive sound behaviour, allowing to accurately focus the sound on the audience, avoiding unnecessary dispersions in areas where acoustic coverage is not required

• The line-array optimisation takes into account the system behaviour with respect to the frequency:

• as distance from the line-array increases, air attenuation increases as well. This particularly applies to high frequencies.

• as the angle of the line-array components increases decreases mid-frequency phase coupling

• as the number of line-array modules low frequencies add together in an acoustically coherent fashion The DSP-managed control functions allow to optimise the line-array sound conguration of the DVA K5 modules. The user interface is simple and intuitive. It includes two rotary encoders installed in the “DSP Preset” (4) section and the reference label shown below: CONFIGURATION AND OPTIMISATION WITH DSP IN LINE-ARRAY
