NHT Powered Subwoofers Speaker User Manual


 
Connecting The Ten OR Twelve
Caution: Before connecting the Ten OR Twelve to your
audio system, it is important to unplug or turn off all AC
power connections to connected components such as
receivers, amplifiers, preamplifiers, and processors. Do
not plug in or connect the Ten OR Twelve subwoofer to
AC power until all connections have been made.
Integrating the Ten or Twelve into your surround system
is simple and straightforward when using this connection
method. Your AV Receiver will control all crossover
functions and the Ten or Twelve will control Subwoofer
gain, phase and boundary equalization.
Connect the Subwoofer/LFE Output on your AV Receiver
to the LFE IN on the back of the Ten or Twelve. (Fig. 2)
In the event your receiver or pre-amp does not have a
LFE or Subwoofer output the Ten/Twelve has two addi-
tional connection methods:
1) Line Level
Use if:
You have an amp or receiver with Pre-Out jacks but no
LFE/Subwoofer jacks.
To connect for a Line Level signal (Fig. 3), keep your
main speakers connected as usual, but use RCA line-
level cables to connect as follows:
Preamps with Line Out jacks: connect one pair of Line
