6.0 Connecting Evolution Electronics to Your
System.
There are a number of methods by which you
can connect the X1 Active Crossover and A1
Amplifier to the rest of your system. The method
you choose will be determined largely by the
surround components in your system. This
becomes particularly important in the manage-
ment of bass frequencies. The Evolution elec-
tronics were designed with flexibility and com-
patibility in mind.
The following section will take you through the
steps in making the final connections in your
system. If for some reason the methods
described in this Owner’s Manual don’t work
properly in your system, consult your NHT deal-
er or call us at 1-800-NHT-9993 (648-9993)
6.1 Signal Connections
Review the following connection method
descriptions and use the one that describes
your surround receiver or processor:
Method 1 - Use if there is a Subwoofer Output
(sometimes labeled “LFE”) on your AV Receiver.
Method 2 - Use if there is a pre-amp out/main in
section on your AV Receiver.
Method 3 - Use this method if have a separate
Surround Processor and Amplifier(s).
Method 1
Integrating the X1 into your surround system is
simple and straightforward when using this con-

all crossover functions and the X1 will control
gain, phase and boundary equalization (see 8.3
below).
Connect the Subwoofer/LFE Output on your AV
Receiver to the LFE IN on the X1 active
crossover.
Method 1 - Recommended Surround Settings
We recommend setting the speaker size in your
