CP-450 REAR PANEL
5. Speaker Outputs
Two sets of removable stereo connectors for speakers in up to two
independent audio zones.
6. Source Inputs
Two (2) sets of left and right RCA jacks from audio sources.
7. AC Power Socket and Fuse
Three-pin grounded socket to connect removable AC power cord with a
T2AL 250V fuse.
8. RS-232
DB-9 jack for RS-232 control of the CP-450 from a control system. See
Chapter 3 Installation & Operation for RS-232 control details.
9. IR In/Out
The 3.5mm mini IR In jack allows the CP-450 to be controlled by IR.
The 3.5mm mini IR Out jack allows for buffered IR output of the IR In
for controlling additional CP-450 units in a cascaded conguration.
10. 12V DC Out & 3-30V AC/DC In
The CP-450 can be turned on automatically by an outside trigger when
the remote power switch is set to “Trigger.” The voltage used to turn
on the CP-450 is applied to the “3-30V DC/AC In” socket, and
can come from an RTI system controller or another CP-450 (if used in
a cascaded conguration). The “12V DC Out” socket provides a +12VDC
that can be looped to the “3-30V DC/AC In” socket to trigger another
CP-450 in a cascaded conguration.
11. 115/230 AC Voltage Switch
Switch used for toggling between 115 Volts and 230 Volts for certain
international locations. The red voltage switch should be left in the 115
Volt position if used within the United States.
