INSTALLATION
DVA system has obtained the TÜV certification for suspension of DVA T4 and DVA
S10dp speakers through flybar stirrup DRK 10.
The report certifies that the maximum weight applying to DRK 10 flybar is 250Kg.
DVA T4 configuration
The DRK 10 flybar attests that the maximum number of DVA T4 is 16.
Refer to table 1 to determine the total weight borne by flybar according to the different
DVA T4 configurations.

DVA S10dp configuration
The DRK 10 flybar attests that the maximum number of DVA S10dp with Neodymium
woofer is 4 and DVA S10dp with Ceramic woofer is 5.
Refer to table 2 to determine the total weight borne by flybar according to the different
DVA S10dp configurations.
Structural modification of DRK 10 flybar
No structural modifications may be made without the manufacturer's consent.
Use only dB Technologies original parts

Use only dB Technologies original parts.
The TÜV authorizing body has not certificated any other parts for use!
Always install parts in accordance with these installation instruction!
Compile and store all DVA system documents in a safe place!
Warning
If the security norms and total weight calculations are not observed, dB Technologies
is not responsible for any possible damage to people and things.
Note
During installation ensure that carrying structure of the system has added in the total
weight also the DRK 10 flybar weight, chain hoists, motors, cables and further weights.
Initiation and Operation
The safety regulation “ § 39, VBG 9a” of the German employers' liability insurance
association's accident prevention regulations requires that load-carrying equipment be
inspected by a qualified expert and possible defects be eliminated prior to initial
commissioning by the recipient.
The safety regulation “ § 41, VBG 9a” requires that load-carrying equipment be subjected
to a non-routine inspection following damage, repair work and other incidents that can
affect load-carrying capacity.
Warning
The safety regulations might be different in other countries. Please check with your
national safety authority the valid regulations!

Mixed configuration with DVA T4 and DVA S10dp (Neodimium woofer)
The modular structure of DVA system permits mixed suspension configuration between
DVA T4 and DVA S10dp. It is necessary to consider that one DVA S10dp hanging
subwoofer corresponds, in weight terms, to about four DVA T4 speakers.
For this reason it is necessary to calculate the total weight according to the different
configurations.

DVA Composer Acoustical Simulation and aiming for DVA Systems
DVA Composer is a 2D software for aiming and simulating acoustical response of all line
arrays and Subwoofers from DVA Series.
The software allows you to set up a stereo system composed by tops and subs, and
simulates separately the acoustical response of both.
DVA Composer also gives to the user all the information about phase alignment between
flown systems and ground stacked subwoofers, as well as it suggests an optimized
aiming of the line arrays modules and their suggested EQ presets, in order to guarantee
maximum performances even for non-expert customers.
It is recommended to download DVA_Composer free software directly from
dB Technologies (www.dbtechnologies.com) in the special section «Software
& Controller»
