SI 1 Integrator
Owner Information
Thank you for purchasing the THIEL SmartSub Integrator. It has been engineered to provide a very high
level of performance and incorporates innovative (patent pending) concepts in its design to solve the
integration and balance problems subwoofer systems usually exhibit.
In addition to the hookup and adjustment instructions contained in this booklet, the Setup and
Adjustment Flow Chart on page 8 may (but doesn’t have to be) used as a reference for all aspects of
SmartSub and Integrator system configuration, hookup and adjustment.
You are welcome to contact our Customer Service department with any questions or for help in setting
up this system. Our contact information is:

Introduction
The SI 1 SmartSub Integrator provides unprecedented ability to perfectly match a SmartSub with any main speakers and
provide total system performance that is as well integrated and balanced as a full range speaker. This superior performance is
achieved by innovative circuitry (patents pending) that automatically calculates the ideal subwoofer response to perfectly
match the characteristics of the main speakers. Therefore, instead of the usual crossover controls that tell the subwoofer how
to perform, the SmartSub Integrator has settings for the characteristics of the main speakers you are matching, the
configuration of your system and the performance you desire. This information is then used to automatically calculate and
implement the ideal subwoofer response. In addition, the unit enables the total system to operate in either augment or
crossover system mode and can control up to 16 subwoofer units in either mono or stereo configuration.
Connecting the Integrator
The SmartSub Integrator is connected 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, one subwoofer from each
channel needs to connect to the Integrator
For multiple subwoofers, one subwoofer is connected to
the Integrator and the others are daisy-chained, with the
second unit connected to the first, 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 its LFE or
subwoofer output is connected to the Integrator’s LFE
input.
The Integrator has two modes of operation available,
Augment or Crossover, which may use different methods of
connection. Augment mode should be used if you wish to use
the main speaker normally, receiving the full-spectrum signal,
and are therefore using the subwoofer to “fill out” the deep
bass response of the main speakers. Crossover mode should
be used if you wish to restrict the bass energy that the main
speakers will reproduce, transferring this energy to the
subwoofer.
If you wish to have the ability to switch between these
two modes of operation, then crossover mode connections
must be used.

Crossover mode connections
If the main speakers are not able to play loudly enough or
you desire to limit their bass extension to achieve better
performance, then the Integrator should be connected for
use in “Crossover” mode. In this case the preamp/processor
left/right outputs are connected to the Integrator inputs and
the Integrator outputs are connected to the power amplifier
inputs. Either balanced or unbalance connections can be
used depending on which type of connections isa vailable
from the preamp/processor and to the amplifier. This
connection method can be used for operation in both
Crossover and Augment mode.
Augment mode connections
If the main speakers are able to play loudly enough and
therefore the subwoofer is needed only to extend the bass
range of the main speakers (in addition to reproducing the
subwoofer channel in video systems), the Integrator can be
used in “Augment” mode. In this case the above connection
method may be used, or, the main speaker system hookup
can be left as-is, with no changes, and 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 first (speaker level) input connection
method, connect cables from the power amplifier output
terminals to the respective speaker level input terminals on
the Integrator. Be careful to 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.
The second (line level) method is implemented by
connecting 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.

If the subwoofer
is used in
Augment mode,
these speaker
level input
connections may
be used. Wires
to these
terminals are
connected from
the main speaker
power amplifier.

This
connector is
used to
supply
the LFE
signal
from the
processor.
For Crossover
mode either
these inputs 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
connectors are
used as
an
unbalanced
alternative to
the
balanced
inputs.
For crossover
mode
connection
these
connectors or
the unbalanced
outputs are
used to supply
the crossover’s
output to the
main speaker
power
amplifier’s
inputs.
These
connectors are
used as
an
unbalanced
alternative to
the
balanced
outputs.
These connectors
are used to
supply signal to
the subwoofer
unit(s).
These connectors
are used to add
the output from
another Integrator
into the
Subwoofer signal.
This
connector
is used to
remotely
control the
unit as an
alternative
to a handheld
remote
control.
