word "BRIDGED" on the panel above the 4-terminal connector when connecting the 2-conductor wire to the
speaker.
13. REMOTE MASTER ON/OFF CONTROL. This 2-terminal connector allows the entire PA635 to be powered
ON and OFF by a control voltage ranging between 5 and 30 Volts DC (16mA @ 12 V). Be sure to observe
the marked polarity. For instance, the 12 volt common CO (Control Output) of the Xantech ZPR68 preamp
will power the PA635 ON and OFF automatically with the first zone ON and last zone OFF commands. The
DC Voltage must be applied continuously to retain the ON condition and drop to less than 0.5 Volt to switch to
the OFF condition.
NOTE: The front panel POWER switch (item #3) must be left in the Manual OFF (Out) position and the
Master AC Line Switch (item #17) set to ON (I) to permit the REMOTE MASTER ON/OFF CONTROL to
operate. See also CAUTION notes, Fig. 9.
14. Rear Panel ON/OFF LED. This LED indicates the power ON/OFF condition of the entire PA635, whether
activated by a REMOTE MASTER ON/OFF CONTROL voltage (item #13) or from the front panel POWER
switch (item # 3).
15. Common IR IN and STATUS Connector. This 4-terminal connector provides the same type of IR control
functions as that of the individual amplifier pairs (item #11) except they apply to all amplifier pairs in common.
That is, IR commands for Volume, Mute, etc., control all amplifier pairs together.
NOTE: Individual control of amplifier pairs is possible, however, through the Common IR IN, provided the IR
Code Group is changed on amplifier pairs you wish to control separately. The STATUS output goes high and
low with the AC Power ON/OFF state of the entire PA635. It does not respond to a Common IR OFF/ON
(Standby) condition.
16. Grounding Screw. Provides a means for chassis connection to earth ground or to other A/V products to aid
in the reduction of system noise, etc., where needed.
17. Master AC LINE ON/OFF Switch. Turns power OFF to the entire PA635, regardless of IR, Control IN, or
front panel POWER switch conditions. Must be placed in the ON (I) position for the other power switching
functions to work.
18. 3-Conductor AC Line Cord Receptacle. Standard IEC male receptacle for plug-in of a 3-conductor power
line cord. Depending on the application, plug the line cord into a switched or un-switched 120V 60 Hz AC
outlet (or 240 VAC 50 Hz on the 240 V version).
RC68+ (or RC68) Programmer / Remote Control
The RC68+ Programmer (available separately) contains all the commands necessary to operate the IR control
functions of the PA635.
You will need it to program universal learning devices such as the Xantech URC-2 learning remote, Xantech
SmartPads, 590-10 Programmable Controller, 710 Fone Link, etc., with commands that operate the PA635.
NOTE: The RC68+ codes operate many other Xantech models as well, such as the RGC11, CC12, ZPR68, etc.
Therefore, only the button descriptions that apply to the operation of the PA635 are listed below. All others
should be ignored.
CAUTION: While the RC68+ can be used as a handheld remote control, it is highly recommended it not be given
to the final user for the following reasons:
• Since it includes adjustable code groups, the user may inadvertently alter the installer configurations.
• Also, since the user will require IR commands from other brands of equipment to control the total system,
in addition to those of the PA635, all commands should be consolidated into one learning device, for ease
of use.
