LFE Configuration
The SmartSubs can be used in four ways depending on
your requirements:
1. As a stand-alone unit.
2. With a passive crossover.
3. With the SmartSub Integrator in augment mode.
4. With the SmartSub Integrator in crossover mode.
The configuration chosen will determine your required
equipment, hookup connections and processor settings.
Which system configuration is best for you depends mainly
on the capabilities of your main left/right speakers.
Additional discussion of these options can be found in
the section Crossover Use. In addition, there is a
comprehensive flow chart for your reference on pages 12 and
13 that guides you through all aspects of system
configuration, hookup, and adjustment. More information
on Integrator hookup and adjustment can be found in that
product’s manual.
System Configurations
6
In this configuration the subwoofer is used only for reproduction of
the ‘point one’ subwoofer channel and is driven by the processor’s
subwoofer output connected to the subwoofer’s LFE input.
This configuration is a good choice when the main speakers play
sufficiently loud and their bass is satisfactory for applications other
than movie effects.

Passive Crossover Configuration
1 If your main speakers play sufficiently loudly for all
your uses and they reproduce the bass with satisfying
completeness, then the subwoofer is only needed to
reproduce the LFE (low frequency effects, or subwoofer)
channel and it can be used in the LFE configuration
without a crossover or Integrator.
If your main speakers play sufficiently loudly for all your
uses but do not reproduce the full low frequency range of the
left/right channels, you should also use the subwoofer to
augment the bass response of your main speakers. This can
be accomplished without altering the signal or wiring to your
main speakers by using one of the next two configurations.
2 A SmartSub Passive crossover can be used if one is
available to match your main THIEL speakers and if low
frequency adjustments are not required.
A two-channel crossover is illustrated but a five-channel
unit is also available to allow the subwoofer to augment the
bass of five channels.
This configuration has connections and benefits identical to the
following one except the passive crossover provides no adjustments
and is available for only selected THIEL model main speakers.
