Thank  you  for  purchasing  the  Phase  Technology
®  CI150  high 
denition in-wall speaker system. Each pair of the CI150 makes an 
LCR conguration. There is no need for a separate center channel 
speaker.  This  is  done  by  combining  the  output  of  each  CI150’s 
center  channel  speaker. By  running both lower  speakers from the 
center channel output on your amplier the content sounds like it is 
coming from the center of the TV screen. Because of this, special 
consideration must be taken to run two sets of speaker leads to each 
CI150. One will be connected to the left (or right) channel on your 
amplier and the other will be used on  each CI150 for  the center 
channel.  When you are ready to connect the speaker leads to your 
amplier you will have a set of leads for the left and right channel 
and T WO sets of leads for the center channel. The CI160 is more of 
a traditional LCR speaker, unlike the CI150. Each CI160 speaker is 
used for a single Left, Right, or Center channel.
The mounting frame on the CI150/160 is made of extruded aluminum 
and has a uniquely designed self-aligning clamping system to secure 
the ange assembly to the drywall. This patented design simplies 
installation and reduces unwanted wall vibration resulting in improved 
performance and denition.
All  CI  Series  speakers  include  self-resetting  solid-state  PTC 
protection  circuits. This  unique system  is  able to detect  when  the 
speaker is being over-driven and lowers the speaker volume until the 
problem is corrected. The PTC device then resets itself for normal 
operation. 
Regardless  of  application,  serious  audiophile  listening  or  home 
theater, we recommend that you take the time to read this manual 
thoroughly before connecting speakers to your amplier or receiver. 
In the highly unlikely event that you should experience a problem with 
set-up or operation, please contact one of our authorized dealers for 
assistance, or contact us directly.
