INPUT, OUTPUT AND CONTROL SECTION

1. INPUT ("Balanced audio Input")
Input compatible with balanced XLR
cables. Used for connection of the
audio signal coming from the mixer
or from another speaker.
2. OUTPUT ("Balanced Audio Link/
Xover). Output compatible with
balanced XLR cables. Used to link
the signal to another subwoofer or
to the other line-array modules in
daisy-chain ("link") configuration.
As an alternative, for configurations
that require the application of a
crossover ("Xover"), it links a filtered
signal at the set frequency [8]. The
use type selection is carried out
through the selector [7].
3. SUB ATTENUATION
Allows adjusting the attenuation of the subwoofer using the input volume. We recommend to set to 0 dB before
starting assembly.
4. DELAY CONTROL ("Delay" [ms])
The two rotary switches allow setting the subwoofer signal delay within the 0-9.9 ms range. The first switch
adjusts delay total value, the second one the decimal value.
5. POLARITY SWITCH ("Polarity")
Allows reversing subwoofer audio polarity. It can prove useful to align the phase among the different subwoofers
or between a subwoofer and the line-array modules. For further information, refer to
PARAMETERS.
6. CARDIOID MODE SWITCH ("Cardioid preset")
Allows configuring the cardioid use with a single command. If this mode is selected, the "Active" LED is ON and
the polarity and delay values are by-passed, as they are already preset.
7. "LINK" OR "XOVER" USE SWITCH
Switch that determines the type of output present at connector [2].
8. XOVER FREQUENCY SWITCH ("Xover [Hz]")
It selects the XOVER frequency (60-70-75-80-85-90-100-110-Fullrange) applied to output [2]. The Service/User
position must be used for the firmware update status or to recall a USER setting (refer to the DBTECHNOLOGIES
NETWORK manual). Refer also to the
9. STATUS LEDs ("Status")
LEDs relating to module operation. A table in next page summarizes the meaning of the different LEDs.
