This specific design has made it possible to obtain a constant and precise 100° coverage in a
horizontal direction and 10° coverage in a vertical director for each diffuser. CONTROLS AND FUNCTIONS
"Balanced Audio" section
1) " INPUT” INPUT CONNECTOR
Balanced input at line level. It is able to accept “XLR” sockets.
2) "LINK” OUTPUT CONNECTOR
The “XLR” connector connected in parallel with input (1) can be used to send the input
audio signal to another amplified speaker.
"Status" section
3) “LIMITER” INDICATOR LIGHT
This indicator comes on red to indicate that the internal limiter circuit has tripped.
This prevents amplifier distortion and protects the speakers against overloads.
Always avoid operating conditions where the system works for long periods of
time with LED flashes or it is always ON
4) “SIGNAL” INDICATOR LIGHT
This indicator comes on green to indicate the presence of an input signal to a level
higher than-20dBu.
5) “MUTE/PROT” INDICATOR LIGHT
This yellow indicator indicates amplifier status. In normal operating conditions, the LED
is off; if it flashes or is always on, refer to the diagnostics table to check amplifier status.
6) “READY” INDICATOR LIGHT
This indicator comes on green to indicate that the main power voltage is correct. In
normal operating conditions, the LED is on; if it flashes or is off, refer to the diagnostics
table to check amplifier status.
"Input control " section
7) “INPUT SENS” INPUT SENSITIVITY CONTROL
This control regulates the sensitivity of the signal amplifier input.
This control does not affect the “BALANCED LINK/OUT” output level
"RDNET " section
8) INPUT CONNECTOR "DATA INPUT”
RJ45 connector 'data input.
9) OUTPUT CONNECTOR "DATA INPUT”
RJ45 connector 'data output for cascading connections.
10) “LINK” INDICATION LIGHT
This green indicator turns on only when the amplifier has recognized and is
connected with the main RDNET unit via the computer.
11) “ACTIVE” INDICATOR LIGHT
This yellow indicator flashes when there is an active data transmission between
RDNET and the amplifier module.
DVA Network
DVA USB Manager
The firmware of the amplifier module can be updated via the USB port.
To make this update possible and simple, a dedicated program has been developed.
DVA T12 is equipped with proprietary network interface, called RDNET, for PC interface
through a device (RDNET control).
For this purpose, a proprietary communication protocol has been developed for receiving and
sending data; this connection permits real-time monitoring of the diffuser parameters, such as
output power, amplifier temperature, limiter status, etc...
It is also possible to select various equalizations or create new ones, set the desired volume
levels using the specific plug-in.

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.
