Model PA1235X

CAUTION: When making connections for the BRIDGED mode, remember, only one speaker is being attached per amplifier pair. Be sure to observe the outer "+” and "–" polarity markings on each side of the word "BRIDGED" on the panel above the 4-terminal connector when connecting the 2-conductor wire to the speaker.

10.Remote Master On/Off Control. This 2-terminal connector allows the entire PA1235X 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 PA1235X 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.

11.Rear Panel ON/OFF LED. This LED indicates the power ON/OFF condition of the entire PA1235X, whether activated by a REMOTE MASTER ON/OFF CONTROL voltage (item #13) or from the front panel POWER switch (item # 3).

12.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., if needed.

13.Master AC LINE ON/OFF Switch. Turns power OFF to the entire PA1235X, regardless of Remote Master or front panel POWER switch conditions. Must be placed in the ON (I) position for the other power switching functions to work.

14.3-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).
