CHARACTERISTICS AND PROTECTION
The speakers’s components in the box are protected by 1.5mm metal steel grille covered
by foam on backside.
Connecting to the mains supply
Each active speaker features its own power cable. Connection is done by a Neutrik
POWER CON® (blue) model which permits easy and fast connection to the speaker as
well as being an excellent locking system.
The same connector serves as a switch to turn ON and OFF the active loudspeaker by
turning the connector to the left (OFF) or right (ON).
The active speaker must be connected to a power supply able to deliver the maximum
required power.
Main power supply linking (present only DVA S1518N)
On the rear of the speaker, a Neutrik POWER CON® connector (grey) offers linking the
mains power supply.
This socket links the power supply to another speaker, thereby reducing the direct
connections to the mains. Maximum amplifier input power is shown on the amplifier panel.
The maximum number of speakers connected together varies of max input power and of
the maximum allowed current of the first power socket.
Front Grille
Cooling
Thermal control is managed by the main microprocessor that interacts with the local
microprocessors (amplifiers and power supply) and communicates the data to the DSP for
any corrections.
If the amplifier module heats up excessively, the volume is gradually reduced step wise to
0.1dB until the module is thermally stabilised.
The volume is automatically restored when the normal operating temperature is reached.
Failure indications and safeties
The microprocessor is able to signal three different kinds of failure by flashing the
“READY”, “MUTE
/PROT ” e “LIMIT”
The three types of failure are:
1) WARNING: a non severe error or auto-ripristinate malfunction is detected and the
performance of the speaker is not limited
2) LIMITATION: an error is detected and diffuser performance is limited. The sound
level is reduced or one or more amplifiers are disabled.
This state partially influences the correct functioning of the diffuser.
If the problem persists the next time the module is turned on, contact the support
centre for assistance.
3) FAILURE: a severe malfunction is detected. The speaker switches to “mute”.
If the case of a malfunction, before contacting the support centre, try to turn the
module off and on to check if the problem still exists.
WARNING
Never use the handle to hang the speaker!
LOUDSPEAKER INSTALLATION
WARNING
Make sure that the loudspeaker is securely installed in a stable position to avoid any
injuries or damages to persons or property.
For safety reasons do not place one loudspeaker on top of another without proper
fastening systems.
If you use the loudspeakers outdoors avoid places that are exposed to bad weather.
The loudspeaker is supplied by the manufacturer company for use in support
