12) “Remote Preset Active” INDICATION LIGHT
This yellow indicator indicates the exclusion of the Volume control and the “DSP
Preset” rotary switch (13) when the amplifier is remotely controlled by a
computer via RDNET.
The indicator flashes slowly if the rotary switch is set to 9 and a previously saved
user equalization has been stored.
13) “DSP Preset” 10-position ROTARY SWITCH
This 10-position rotary switch makes it possible to select the nine preset
equalization curves (selector 0-8) or to select the equalization previously saved
by the user via RDNET (selector 9).
If this option is not used, curve 9 will be equal to curve 0
Refer to the table for the correspondence of the equalization curve.
14) “Service Data USB” Connector
Via this USB connector, it is possible to update the firmware of the DVA T8
amplifier module using the computer and a dedicated program.
15)
"MAINS INPUT" POWER SOCKET
For connecting the power cable.
The connector used for mains connection is a POWER CON® (blue)
16)
“MAINS OUTPUT LINK” RELAUNCH POWER SOCKET
For relaunching the mains power. The output is connected in parallel with input (15)
and can be used to power another amplified speaker.
The connector uses a POWER CON® (grey)
17)
"MAINS FUSE" FUSE CARRIER
Mains fuse housing.
CHARACTERISTICS AND PROTECTION
The speakers’s components in the box are protected by 1.2mm metal steel grille
covered by foam on backside.
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.
Power on
The diffusor is powered up normally by an initialization process during which the
module is powered by the auxiliary power supply.
When all of the amplifier peripherals are correctly detected, the main power supply is
activated.
The IPOS technology (Intelligent Power-On Sequence) introduces a random and
differentiated delay for each module prior to the power on of the main PSU (Power
Supply Unit).
This prevents the breakaway starting currents of the various modules from
accumulating, overloading the AC power supply line.
At the end of the power on procedure, only the green “READY” LED will remain on
fixed on the amplifier module.
Failure indications and safeties
The microprocessor is able to signal three different kinds of failure by flashing the
“READY”, “
” and “LIMIT” LED as reported in the table of diagnostic.
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.
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
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.
