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,

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
