VIO L208 cod. 420120268Q rev.1.1

www.dbtechnologies.com [e-mail]

Thank you for choosing a dBTechnologies Product!

VIO L208 is the new dBTechnologies flagship 2-way professional active line array module. It is equipped with: one

1.4” neodymium compression driver exit (2.5” neodymium voice coil) and two 8” neodymium woofers (2” voice coil).
The full-range acoustical design includes an efficient all-in-one panel with phase corrector, in order to reach the best
coherence in line-array configuration. The mechanical design allows an easy, accurate and quick installation in flown
or stack use. The powerful DIGIPRO® G3 amplifier section, capable of handling up to 900 W (RMS power), is
controlled by a DSP, which can perform a detailed customization of the output sound of the speaker. In particular,
thanks to the dual rotary encoder interface, it is possible to accurately tune the line-array configuration coverage,
using the FIR filter technology. In addition, the integrated RDNET connections are useful for a remote in-depth line­array control and configuration.

4) First switch on for line-array setup

The DIGIPRO G3® amplifier of VIO L208 is controlled
by a powerful DSP. All the connections and controls
are in the rear amplifier control panel:

1 – Balanced audio input and output link
2 – Audio Attenuation rotary switch
3 – RDNet Data In / Data out
4 – DSP PRESET rotary switches (Speaker
coupling/High frequency compensation)
5 – Status LEDs (Limiter, Signal, Mute/Protection,
Ready)
6 – Control LEDs (Link, Active, Remote preset Active)
7 – Mini B-type USB port for firmware updating
8 – Auto-range Mains Input
9 – Mains link output
10 –Mains fuse

WARNING

The fuse is factory set for 220-240V~ operation.
If it is necessary to change the fuse to 100-120V~ range:

1. Turn off the power and disconnect the speaker from

any cable.

2. Wait 5 minutes.

3. Substitute the fuse with the correct one supplied.

a) Once you have properly set up the mechanical
line-array configuration (see also the VIO L208
complete user manual and accessories instructions for
further information), connect the audio input (1) of the
first module of the array. Then connect the useful link
audio output (1) to other VIO L208 modules, for the
connection of all the line-array elements. Set the Audio
Attenuation (2) of the loudspeakers to 0 dB.

b) Check the rear panel
reference label for a proper DSP
regulation in line array. Please
note that this kind of
configuration can be set and
modified also by the use of
remote controller (RDNet
Control 2 or RDNet Control 8)
and software (Aurora,
dBTechnologies Network, from

3.4 version). For this information
see the chapter 5.
In this rear label (“SUGGESTED
CONFIGURATIONS”) you can
find the suggested position of
rotary switches (4) for each type
of installation (Speakers
Coupling positions and High
Frequency Compensation).
These settings are the main
acoustic corrections to create
the proper coupling between
the elements of your line-array,
in order to obtain the best
coverage conditions.
In particular, the “SPEAKER
COUPLING” rotary acts mainly
on low frequencies, and it can
be set in 6 positions, depending on the number of
elements of line-array.

VIO L208 5 cod. 420120268Q rev.1.1

www.dbtechnologies.com [e-mail]

A seventh “Bass boost” position assign particular
emphasis on the lower frequencies. The “service/user”
one allows USB port communication for firmware
updating (or can recall on the speaker user settings
previously saved in remote control with
dBTechnologies Network). The “HIGH FREQUENCY
COMPENSATION” can act on medium-high
frequencies. The user can choose among a “FLAT”
position (which give a flat equalization in this
frequencies band), and other 7 positions, depending
on the distance between the line-array and the
audience (in meters and feet).

c) Connect the power link output (9) of the first
module to the mains input (8) of a second VIO L208
module of the line-array, and so on, in order to link
the power supply between all the elements. The
maximum linkable rated power and current depends
on the first module connection (type of cable, type of
connector used). The plate data give information
about the entire linked line-array system. The
maximum number of modules for each power daisy
chain connection [mains input + mains link] is: 1+5
VIO L208s** at 220-240V~, and 1+3 VIO L208s** at
100-120V~ (for further information see Technical
Data).

d) In case of remote control, connect the proper
Data Input (3) of the first module of the line-array to
the hardware remote controller (RDNet Control 2 or
RDNet Control 8) with cables equipped with etherCON
connectors. Then connect the Data Output (3) of the
first module to the Data Input (3) of the second one,
and so on. When the RDNet network is on and it has
recognized the connected device, the LED “Link” (6) is
on. The other LED (6) “Active” start blinking when
there is the presence of data transmission, the
“Remote Preset Active” advise that all the local
controls set on the amplifier panel (level, DSP presets,
etc.) are by-passed and controlled remotely by RDNet.
See also RDNet Control 2 and RDNet Control 8 user
manuals for further information.

e) Connect the power supply (8) to the first
module. The related “Ready” LED (5) turns on,
signaling the proper power connection. The “Signal”
LED (5) start blinking at the presence of audio signal
(greater than -20dBu). Avoid audio distortion
conditions, potentially signaled by the “Limiter” LED
(5).

IN FLOWN CONFIGURATION, IT IS ADVISABLE
TO START ALL THE CONNECTIONS FROM THE

TOP (“FIRST ELEMENT”) OF THE LINE-ARRAY,
FOR THE BEST CABLING, IN ACCORDANCE WITH THE
FOLLOWING SCREENS OF “DBTECHNOLOGIES
NETWORK” SOFTWARE.

5) Software (Aurora, dBTechnologies Network and
dBTechnologies Composer)

VIO L208 can be fully remote controlled via RDNet.
The connection details have been illustrated in the
chapter 4 (“d” point). In remote control mode, the
use of free professional software, developed by
dBTechnologies, allows a complete system
management: Aurora Net, dBTechnologies Network.
dBTechnologies Composer is a predictive software
for the design and the check of acoustical and
mechanical settings. They can be downloaded for
free from the official site:

www.dbtechnologies.com/EN/Downloads.aspx

Check always for software updates!

a) Aurora Net

The software which must be used in case of remote
control is Aurora Net. This cross-platform product
allows the user controlling, setting and organizing all
the ViO family. It also fully supports DANTE audio
networking. Check the site www.dbtechnologies.com
for further information.

b) dBTechnologies Network
A second
software which
must be used in
case of remote
control is
dBTechnologies
Network (from
the version no.

3.4). This
software can
control different
speakers in
different
configurations.
It allows a
complete remote
control and a full
real-time
monitoring in
various scenarios. For example, the user can control a
setup with 2 line-arrays of VIO L208 and 3 VIO S118
subwoofers, and change different parameters while
the entire system is sounding.
It can also offer a deeper loudspeaker control than the
simple rear amplifier panel rotaries.

VIO L208 6 cod. 420120268Q rev.1.1

www.dbtechnologies.com [e-mail]

Those VIO L208 parameters can be controlled by
using dBTechnologies Network:

- MUTE/SOLO switch*

- INPUT ATTENUATION

- SPEAKERS COUPLING

- HIGH FREQUENCY COMPENSATION

- HPF FILTER PRESET*

- DELAY*

The * parameters can be controlled only via
software.

LAST SETTINGS STORED ON VIOL208 (USING
DBTECHNOLOGIES NETWORK SOFTWARE),

CAN BE RECALLED LATER ON THE SPEAKER,
WITHOUT RDNET REMOTE CONTROL: SIMPLY TURN THE
ROTARY “SPEAKER COUPLING” ON “SERVICE/USER”
POSITION.

c) dBTechnologies Composer

The software dBTechnologies Composer (from
version no. 6.4) is useful for complete sound
systems design. It has been developed to optimize
complex acoustical settings like line-array alignment
and to calculate easily all parameters needed in
professional sound system scenarios.

It is used to predict completely the acoustical
behaviour of professional dBTechnologies products
in an immediate way.
In particular, it can simulate different parameters,
for example: mechanical safety in fly-bar use, SPL
levels in outdoor environment, system coverage,
system delays. The user-friendly graphic interface
helps the user to easily understand in-depth
settings.
