These speaker
level inputs may
be used for
operation in
Augment mode.
Wires to these
terminals are
connected from
the main speaker
power amplifier. For crossover
mode
connection
these or the
unbalanced
outputs are
used to supply
the Integrator’s
output to the
main speaker
amplifier’s
inputs. For Crossover
mode either
these or the
unbalanced
inputs must be
used to receive
input from the
processor or
preamp. For
Augment mode
operation they
are an alternative
to the speaker
level inputs. These
are an
unbal-
anced
alterna-
tive to
the
bal-
anced
outputs. These
are an
unbal-
anced
alterna-
tive to
the
bal-
anced
inputs. These connectors
are used to
supply signal to
the subwoofer
unit(s).

Connect the SmartSub Integrator to the subwoofer
with an XLR type balanced interconnect cable from the
units’ Sub Output to the subwoofer’s Normal Input. If stereo
subwoofer operation is used, connect one subwoofer from
each channel of the Integrator.
For multiple subwoofers, connect one subwoofer from
the Integrator and daisy-chain the others, with the second
unit connected from the first’s Normal Output, etc. Or, if
two subwoofers are used in mono operation, they can both
be connected to the Integrator using the left and right
outputs.

If the system has a surround processor then connect its
LFE or subwoofer output to the Integrator’s LFE input.

If you are using a second Integrator or a THIEL
passive crossover to derive a subwoofer signal from channels
of your system other than the left/right channels, then
connect the output(s) of that unit to the “Bridge In”
connectors with an XLR type balanced interconnect cable.
Modes of operation
The Integrator has two modes of operation available,
Augment or Crossover, which may use different methods of
connection.

Augment mode ugment mode
ugment mode ugment mode
ugment mode should be used if you wish to use the
main speaker normally, receiving the full-spectrum signal,
and are therefore using the subwoofer only to “fill out” and
extend the deep bass response of the main speakers. (In
addition to reproducing the subwoofer channel.)

ossover mode ssover mode
ssover mode ssover mode
ssover mode should be used if the main speakers
are not able to play loudly enough or you wish to restrict the
bass energy that the main speakers will reproduce,
transferring this energy to the subwoofer.
Crossover mode connections
This connection method can be used for operation in
either Crossover and Augment mode.

Connect the preamp/processor left/right outputs to the
Integrator inputs.

Connect the Integrator outputs to the power amplifier
inputs.
Either balanced or unbalance connections can be used
depending on which type of connections are available from
the preamp/processor and to the amplifier.
Augment mode connections
In this case the main speaker system hookup is left as-is,
with no changes. The Integrator can receive its input either
from the output of the power amplifier (speaker level) or
from the output of the preamp/processor (line level).
To implement the speaker level input connection
method:
4 4 4 4 4
Connect cables from the power amplifier output
terminals to the respective speaker level input terminals on
the Integrator. Connect the positive amplifier outputs to the
positive Integrator inputs. The cables used for these
connections can be small since no power is being transferred.
Remove the shorting pins when these connectors are used.
To implement the line level input connection method:
4 4 4 4 4
Connect the preamp/processor’s left and right channel
outputs to the respective inputs of the Integrator using either
unbalanced (regular) or balanced interconnect cables since
the Integrator will accept either.
This input connection method can only be implemented
if either the preamp/processor has two sets of such outputs
(since one set is already used for connection to the main
amplifier inputs), or if a “Y” connector is used to split the
output into two cables.
This
connector
is used to
remotely
control the
unit as an
alternative
to a hand-
held
remote
control.
