1 DVA T8 and DVA T12 – Line Array Module
1.1 Compact View
Comm: Green indicates that communication between speaker and Control is working. In case of
communication error the indicator becomes red.
Eq. Sync: Green indicates that actual device Eq. is synchronized with the Group. Eq showed in the DVA
Network software.
Status: This indicator shows the device status. Green indicates normal operation; when it becomes red, an
error condition is occurring.
MUTE: The device can be muted by selecting the button; it turns red when enabled.
SOLO: Allows to listen to only to the selected device. Other devices will be automatically muted.
Light indicators under Speaker Image: shows status of each audio way (Midrange, tweeter and woofer):
Green: audio level of the relevant channel exceeds -40dBfs (decibel full. scale, 0dBfs = maximum
power delivered by channel amplifier)
Red: amplifier delivers maximum power and limiter is active.
Vu-meter bars:
left bar (green) indicates the input signal level (in dBu)
right bar (red) indicates the limiter compression level (in dB) (average of the 3 audio ways)
An indicator located above compressor average level becomes red when maximum signal level allowed on
preamplifier input is reached.
1.2 Expanded View
MF-HF-LF Panels: show advanced parameters for each audio way (Midrange, Tweeter and Woofer).
2/17 Rev 1.0
Each panel contains:
Vu-meter bar on the left (green): channel amplifier output level in dBfs (decibel full. scale, 0dBfs =
maximum power delivered) ;
Vu-meter bar on the right (red): channel limiter compression level in dB;
amplifier temperature: indicated in °C
Status indicator: green = channel is ok; Red = malfunction is detected;
MUTE: single audio way mute
Preset panel: Select a different audio preset (see Speaker User manual).
Group panel: Assign the speaker to a Group Equalizer. When assigned, equalization delay or volume can
be modified in the Group Eq window.
Thermal Limiter: becomes yellow when amplifier module starts reducing Audio volume to prevent
overheating.
FW Rev: Show revision of currently loaded Firmware.
Temp: indicates PSU temperature in °C.
Standby: enter in standby mode to reduce internal temperature and energy consumption in long
inactivity conditions. Button is usually green and becomes red in "stand-by" condition.
Anyway, DVA Network communication remains active and speaker can be reactivated at any time by
pressing the key again.
ATTENTION!!
If activated, standby button will switch PSU module off and will deactivat audio on all 3
output channels.
Factory Default: Allows to reset all settings made via DVA Network software and to restore factory
configuration settings.
ATTENTION
Speaker must be assigned to a group in order to modify the audio equalization.

2.2 Expanded View
Woofer-Xover Out Panels: show advanced parameters for each audio way (Woofer Out and Xover Out).
4/17 Rev 1.0
Each panel contains:
Vu-meter bar on the left (green): channel amplifier output level in dBfs (decibel full. scale, 0dBfs =
maximum power delivered) ;
Vu-meter bar on the right (red): channel limiter compression level in dB;
Status (or active) indicator: green = channel is ok; Red = malfunction is detected;
MUTE: single audio way mute
Delay Preset panel: Select a different audio Delay preset (see Speaker User manual). Delay is indicated in
mS and ranges from 0 to 4.5mS in step of 0.5mS.
The following formula can be used to align an audio signal:
Delay = (GAPx1000)/344
Delay = ms (in milliseconds)
GAP = distance between speaker and reference point (in meters)
Speed of sound = 344 m/s
Inv. Phase performs a phase rotation of 180° respect to the input signal. It turns red when phase rotation is
active.
Xover Preset panel: Select a different audio preset for Xover (see Speaker User manual).
Woofer Low Pass Cut-off Frequency can be selected in step of 5Hz with a slope of 24dB/oct.
An HighPass filter with the same cut-of frequency will be automatically applied to Xover Out.
Group panel: Assign the speaker to a Group Equalizer. When assigned, equalization delay or volume can
be modified in the Group Eq window.
FW Rev: Show revision of currently loaded Firmware.
Temp: indicates PSU temperature in °C.
Standby: enter in standby mode to reduce internal temperature and energy consumption in long
inactivity conditions. Button is usually green and becomes red in "stand-by" condition.
