Connection examples

The very low frequency range reproduced by a subwoofer is essentially
omnidirectional, thus allowing easy installation of
the enclosure. In most cases the subwoofer can be placed near the
satellite loudspeaker system, but when space or set up reason dictate
it, the subwoofer can be positioned at some distance from the satellite
system (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 below and also illustrated on pages 45
and 46 of this manual.
 Always make sure to use only heavy gauge, high quality
shielded cables.
Example A: 1 TANK12SA subwoofer + 2 self-powered loudspeakers
The complex connections that most other systems require for this
configuration are made extremely simple with this subwoofer 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 self-
powered loudspeakers
This set-up allows them to benefit from the increase in dynamic range
provided by the electronic crossover of the subwoofer.

 See connection example A on page 45
• Connect the L and R outputs of the mixer to the L and R inputs
(3) of the subwoofer.
• Connect the X-OVER L and R outputs (2) of the subwoofer to
the inputs of the 2 self-powered loudspeakers.
• The output levels of the two self-powered loudspeakers are
not affected by the 'VOLUME' control (6) of the subwoofer.
Example B: 2 TANK12SA subwoofer + 2 self-powered loudspeakers
This is the most typical configuration where each subwoofer drives one
self-powered loudspeaker.

• Connect the L and R outputs of the mixer to the 'R' inputs (3) of the
two subwoofers.
• Connect the X-OVER 'R' outputs (2) of the two subwoofers to the
inputs of the two self-powered loudspeakers.
• The output levels of the self-powered loudspeakers are not affected
by the 'VOLUME' control (6) of the subwoofers.

Example C: 1 TANK12SA subwoofer + 2 self-powered loudspeakers
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
self-powered loudspeakers

 See connection example C on page 46
• Connect the AUXILIARY output of the mixer to the 'R' input (3)
of the subwoofer.
• Connect the L and R outputs of the mixer to the inputs of the two
self-powered loudspeakers respectively.
• This type of set-up allows you 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 are selected
by means of the AUX send controls on the corresponding channels.
The subwoofer's volume control and the mixer's AUX output level
control adjust only the very low frequencies.

• Connect the L and R outputs of the mixer to the L and R inputs (3) of
the subwoofer.
• Connect the 'LINK' L and R outputs (4) of the subwoofer to the
L and R inputs (3) of the second subwoofer.
