CONTROLS AND FUNCTIONS (Ref. Page 9)
"Balanced Audio" section
1) " INPUT” INPUT CONNECTOR
Balanced input at line level. It is able to accept “XLR” sockets.
2) "LINK” OUTPUT CONNECTOR
EnglishEnglishEnglish
3) “LIMITER” INDICATOR LIGHT
The “XLR” connector connected in parallel with input (1) can be used to send the
input audio signal to another amplified speaker.
"Status" section
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
“PHASE ” SWITCH
11)
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 track of
music and adjust the switch to obtain the best low-frequency sound.
This function it is used also for cardioid configuration.
12) "DELAY” CONTROL
This control allows to delay the sound signal reproduced by the subwoofer.
circuit allows sound-alignment between line array and sub by balancing the various
positions.
This control 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 front side.
This configuration needs at least 3 subwoofers (two with front radiation and one with
rear radiation).
“RDNET " section
This
EnglishEnglishEnglish
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
user manualuser manual
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 “LINK” (2) output level.
"Xover Out " section
8) OUTPUT CONNECTOR
Internal crossover audio balanced output, by XLR connector. The signal f rom thi s
output can be sent to any other amplified speaker.
The crossover frequency can be selected by means “Xover Frequency” switch (9).
9) "Xover Frequency selection 24dB/Oct” SELECTOR
This selector permits selection of crossover frequency from 75Hz to 120Hz (step
5Hz) with a slope of 24dB/Oct.
The frequency choice depends to the reproduction desired and from system
configuration.
10) “Remote Preset Active” INDICATION LIGHT
When the amplifier is remotely controlled via RDNET, this yellow indicator indicates
the exclusion of the below commands:
Volume (7)
Phase (11)
Xover Frequency selection (9)
Delay (12)
7
13) INPUT CONNECTOR "DATA INPUT”
RJ45 connector 'data input.
14) OUTPUT CONNECTOR "DATA INPUT”
RJ45 connector 'data output for cascading connections.
15) “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.
16) “ACTIVE” INDICATOR LIGHT
This yellow indicator flashes when there is an active data transmission between
RDNET and the amplifier module.
“DSP UP-grade " section
17) “Service Data USB” Connector
Via this USB connector, it is possible to update the firmware of the DVA S30n
amplifier module using the computer and a dedicated program.
18) "MAINS INPUT" POWER SOCKET
For connecting the power cable.
The connector used for mains connection is a POWER CON® (blue)
19) 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.
