Processor
If 12V trigger switching of the dispersion mode (monopole/dipole) of the
CT8 DS surround speakers is required, the assigned 12V trigger output
from the surround processor is connected to the 12V TRIGGER IN of one
of the CT8 XO units assigned to a CT8 DS. The other CT8 XO trigger
inputs are connected daisy chain fashion from the TRIGGER LOOP
socket of one to the TRIGGER IN of the next. The TRIGGER OUT sockets
are connected to the relevant CT8 DS speakers. The TRIGGER IN and
TRIGGER LOOP sockets are mono 3.5mm jacks with the positive (12V)
wire connected to the tip of the plug, whereas the TRIGGER OUT socket
is a stereo 3.5mm jack on both the CT8 XO and CT8 DS loudspeaker.
Figure 18 shows the wiring diagram of a typical 5.1 CT800 system having
