Two or more 112SA
The 112SA speaker system is equipped with XLR male (Link)
and female sockets wired in parallel, allowing for easier
parallel connection of more systems.

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.

Connections
NOTE :
Our configuration examples are using the L and R master
outputs of the mixer, but if they are already taken up (as,
for example, in a powered mixer) the
insert sockets can be
used to the same purposes.
Take out the signal from the insert sockets by means of a
stereo jack plug, in which you have previously joined the
RING with the TIP and send it to the inputs of the subwoofer
by means of an unbalanced XLR, as shown here below.
One 112SA + two active speaker enclosures MT160A
(or two MT180A, or two 110A).
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).
NOTE : It is advisable to place the subwoofer in the center, between the
two speaker enclosures.
