active subwoofer
119SA
Two 119SA + two active speaker enclosures 260A
(or 412A, or 415A)
This is the most typical configuration: each subwoofer can
drive one self-powered speaker enclosure.

Connections
!
Always use SHIELDED CABLES.
!
The subwoofer is connected to one of the mixer's AUX
outputs. This type of set-up allows to use the subwoofer to
extend the low frequency response of only those instruments
that really need it (e.g. drum machines, bass, keyboards).
These instruments must be selected using the corresponding
input channel's AUX send controls. The subwoofer's volume
control and the mixer's AUX output level control adjust only
the very low frequencies.
The very low frequency range reproduced by model 119SA
(34
÷
100Hz) is essentially omnidirectional allowing easy
installation of the enclosure.
In most cases the subwoofer can be placed near the speaker
systems, but when space or set up reason dictate it, the
subwoofer can be positioned at some distance from them
(e.g.: under the stage floor).
You must always consider that the extended low frequency
range increases the risk of acoustic feedback, with undesired
'howls' and reduced clarity. It is thus essential to place the
subwoofer on a rigid structure, that does not transmit
vibrations to the microphones.
Some connection examples, among the most common
possible configurations, are described here below and also
illustrated on pages

Always use SHIELDED CABLES.
!
Make sure the 'Flat/X-over switch is pushed (X-OVER mode).
!
The subwoofer volume control adjusts also the speaker
system's level .
First set the volume controls of the satellites to their maximum
settings, then adjust them to obtain the desired tonal balance.

Connect the mixer L-R outputs to the 119SA L-R inputs.
!
Connect the L-R outputs of the 119SA to the inputs of
the 2 'satellite' active systems. This set-up allows them to
benefit from the increase in dynamic range provided by the
electronic crossover of the 119SA.
!
The output levels of the active speaker enclosures used as
satellites are affected by the volume control of the 119SA.
Set the volume controls of the satellites to their maximum
settings, then adjust them to obtain the desired tonal balance.
One 119SA + two active speaker enclosures 260A
The complex connections usually required for this configu-
ration with other systems are made extremely simple with
our 119SA thanks to the L/R outputs of the built-in stereo
electronic cross-over.
NOTE:
It is advisable to place the subwoofer in the center, between the
two speaker enclosures.

One 119SA + two active speaker enclosures 260A
This is a more complex configuration which enables selective
enhancement of the low-frequencies (for example, only on
drums and keyboards, not on voices or brasses).
