The permissible angles are indicated on the bracket itself, including also the “PIN HOLDER” hole for storing the pin in case of transport with the module disassembled.

FEATURES OF THE AMPLIFIER AND CONTROL SECTIONS

The class D digital amplifier is the heart of the DVA MINI G2 modules. It allows delivering up to 400 W RMS, silently and efficiently, without ventilation. System is controlled by a powerful DSP allowing an immediate and quick configuration of the line array in any context of use.

The DIGIPRO G3 panel is made up of:

• Input, Output and Control Section
• Power Supply Unit Section

WARNING!

• Protect the unit from moisture.
• Never attempt to disassemble the amplifier in any way.
• In the event of a malfunction, remove power supply immediately by disconnecting the unit from the power mains and contact an authorised repair centre.

INPUT, OUTPUT AND CONTROL SECTION

1. AUDIO INPUT AND OUTPUT LINK (BALANCED) Balanced XLR connector that allows connecting a line INPUT. A similar type of connector is used to link the output signal to a second module (OUTPUT LINK)

2. DSP PRESET
   It allows setting the necessary optimisation of high frequencies in line arrays depending on the distance and number of modules.

3. RDNet DATA IN and RDNet DATA OUT
   RDNet data input and output compatible with network cables fitted with etherCON/RJ45 type connectors.
   “Data in” must be connected to devices such as RDNet Control 2 or Control 8.
   “Data Out” is used to link the network to other loudspeakers in daisy-chain configuration.

4. RDNet CONTROL LEDs
   LEDs relating to module network operation (RDNet).
   In particular, if “Link” is on the RDNet network is active and has acknowledged the device,
   if “Active” is flashing there is data traffic, if “Remote Preset Active” is on all local control on the amplifier panel are by-passed by the RDNet remote control.

5. STATUS LED Main
   LEDs show monitor status indications at a glance, according to the logic summarised in the table below:

INSTALLATION

A complete set of accessories (DRK-M5 and DT-8MINI as well as other ones that can be viewed on the website at www. dbtechnologies.com) enables fast and effective installation. Purely indicative illustrations are shown below to show installation. For any information on accessories, please follow the relevant instructions.
For examples of connections, see the section below.

ATTENTION!
The product and accessories must be handled by experienced personnel only! Make sure that the installation is positioned in a stable and safe manner in order to avoid hazardous conditions for people, animals and/or objects. The user is required to follow regulations and mandatory laws on safety of the country in which the product is used. For safe use, regularly check the operation of all parts and integrity before use. Design, calculations, installation, testing and maintenance of suspended systems or professional audio stacks must be performed by authorized personnel only. AEB Industriale is not responsible for improper installations, non-compliant with safety requirements.

• Use DBTECHNOLOGIES COMPOSER to set project parameters.
• Make sure that the local parameters of the different modules are correctly set on the single amplifier panels. In particular, check the DSP settings according to design. As an alternative, all parameters can be remotely edited in real time if the line array connection is carried out through the RDNet network (AURORA NET). Nevertheless, in this case, project initial settings should be physically repeated on the modules.
• Transport, through DT-8MINI, the first 4 modules and DRK-M5 fly-bar to the spot in which the line array will be lifted. Have a second dolly (with no fly-bar) ready with other 4 modules for the following assembly stages of the complete line array.
• Fix the brakes on the dolly wheels.
• Fit the first 4 modules with fly-bar according to the instructions above and to accessory instructions.
• Hoist the first 4 modules using a motor and suitable rigging equipment (not supplied) and then continue with the next modules with the second dolly. The connections suggested are for information only.

CONNECTION AND POWER DAISY CHAIN

The figure below shows a general connection where a module 1 is above a module 2. For this purpose, use cables with powerCON TRUE1® connectors (not provided).

• Connect the power supply of module 1 AUTO-RANGE MAINS INPUT (A).
• Daisy-chain the power supply from module1 to module 2, connecting MAINS LINK output (B) of module 1 to AUTO-RANGE MAINS INPUT (C) of module 2.
• Repeat this procedure until connecting the maximum permitted number of the line array modules (refer to section SPECIFICATIONS).

AUDIO AND RDNET CONNECTIONS

The figure above shows a general connection where a module 1 is above a module 2, showing the audio and network connections. To this end, use the not supplied cables with XLR (audio) and etherCON/RJ45 (network) connectors. For further information on the available types of cables, refer also to the image in next page.

• For the audio connection, connect the cable originating from MIXER/LINE to the BALANCED AUDIO INPUT (A) of module 1 of the line array. Re-link the signal between the first and the second module. For this purpose, connect the output BALANCED AUDIO OUTPUT/LINK (B) of module 1 to the BALANCED AUDIO INPUT (C) of module 2.
• Repeat the operation between the second and the third module and so on, until all modules of the line array are connected.
• For network connection, connect DATA IN connector (A) of module 1 to remote controller (RDNet CONTROL 2 or RDNet CONTROL 8). Re-link the signal by connecting DATA OUT (B) of module 1 to DATA IN (C) of module 2.
• Repeat the operation between the second and the third module and so on, until all modules of the line array are connected.
