CONTROLS AND FUNCTIONS

1) "POWER" MASTER SWITCH
This switch permits turning the speaker on and off.
2) "MAINS FUSE" FUSE CARRIER
Mains fuse housing.
3) "MAINS INPUT" POWER SOCKET
For connecting the power cable provided.
The connector used for mains connection is a POWER CON® (blue)
4) "OUTPUT LINK" RELAUNCH POWER SOCKET
For relaunching the mains power. The output is connected in parallel with input (3)
and can be used to power another amplified speaker.
The connector uses a POWER CON® (grey)
5) COOLING GRILLE
These grilles permit cooling the amplifier during operation.
Do not block accesses and clean the grilles whenever necessary to ensure correct
air circulation.
6) " BALANCED INPUT" INPUT CONNECTOR
Balanced input at line level (0 dBu).
It is able to accept "XLR" sockets.
7) "LINK" OUTPUT CONNECTOR
The "XLR" connector connected in parallel with input (6) can be used to send the
input audio signal to another amplified speaker.
8) "BALANCED X-OVER OUTPUT" OUTPUT CONNECTOR
Internal crossover balanced output. The signal from this output can be sent to any
other amplified speaker.
The crossover frequency can be selected by means of the "SUB X-OVER" switch (9).
9) "SUB X -OVER " SWITCH
This switch permits selection of crossover frequency between the sub woofer and
the speakers connected to the "BALANCED X-OVER OUTPUT" connector.
The crossing frequency is selected to 90Hz or 120Hz with a slope of 24dB/oct.
The frequency choice depends to the sound reproduction desire.
It is advisable to use the 120Hz crossover frequency with up to four DVA T4
speakers and the 90Hz crossover frequency with more than four DVA T4 speakers
10) "SUB PHASE " SWITCH
This switch permits 180° rotation of the audio signal reproduced by subwoofer.
Rotation makes for easier optimization of low-frequency reproduction even in the
most difficult installation situations. After completing installation, reproduce a piece
of music and adjust the switch to obtain the best low-frequency sound.
11) "ON" INDICATOR LIGHT
The "ON" indicator light comes on green to indicate the amplifier is switched on and it
is working properly.
12) "SIGNAL -20dB " INDICATOR LIGHT
This indicator comes on green to indicate the presence of the audio signal (at a level
of -20dB).
13) "PEAK" 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.
It is lights for a few seconds during the switching on.
14) "INPUT SENS" INPUT SENSITIVITY CONTROL
This control regulates the sensitivity of the signal at amplifier input.
This control does not affect the "LINK" and "BALANCED X-OVER OUTPUT" output
levels

15) DIGITAL DELAY "SDD - SUBWOOFER DIGITAL DELAY" OPTION
The DVA S10 loudspeaker can be equipped with a delay module (SDD -
SUBWOOFER DIGITAL DELAY) that allows to delay the sound signal reproduced by
the subwoofer.
This circuit allows sound-alignment between line array and sub by balancing the
various positions. The circuit also includes a balanced "XLR" output that sends the
delayed audio signal to other subwoofers. By using a single delay module it is
possible to delay several subwoofers at the same time.
This module can also be used to create cardioid configuration systems. The cardioid
configuration provides a remarkable attenuation of the low frequencies radiated by
the rear side of the subs, without changing the direct radiated signal on the fronside.
This configuration needs at least 3 subwoofers (two with front radiation and one with
rear radiation equipped with SDD module). See appendix for more details.
