CAUTION: Be sure to have the rear AC LINE POWER switch (Item #15) turned OFF (O) when
changing the position of this switch and when making the corresponding speaker connection
changes.
9. FUSE. When required, replace only with a fuse of the same type and rating:
120 V Version: 6.25 AMP 250 VAC, SLOW BLOW.
240 V Version: 3.15 A Time-Lag 250 VAC.
NOTE: Replacement with a fuse of higher rating will not protect the amplifier and will void the warranty.
10. SPEAKER Terminals. These plug-in 4-terminal screw type connectors permit speaker wire sizes up to
12 gauge. When making connections for the STEREO mode, be sure to observe the "+” and "–" polarity
markings, just under the LEFT & RIGHT markings, for each wire pair going to the speakers.
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.
11. 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.
12. REMOTE MASTER ON/OFF and MUTE CONTROL (CI1 & CI2). These two Stereo Mini Jack
connections allow each individual channel pair of the PA435X to be powered ON and OFF and muted by
a control voltage ranging between 5 and 30 Volts DC (16mA @ 12 V). When connected to the C01 and
C02 jacks from Zones 7 & 8 on the Xantech MRC88, this will allow remote Power ON/OFF control directly
from the MRC88 System Controller. This allows the ‘A’ & ’B’ amplifier channel pairs to be individually
controlled by Zone 7 & 8 of the MRC88. (Tip = ON/OFF Standby Control; Ring = Mute Control; Sleeve =
gnd).
NOTE: The front panel POWER switch (item #3) must be left in the Manual OFF (Out) position and the
Master AC Line Switch (item #13) set to ON (I) to permit the REMOTE MASTER ON/OFF CONTROL to
operate. See also CAUTION notes, Fig. 9.
13. 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).
14. Rear Panel ON/OFF LED. This LED indicates the power ON/OFF condition of the entire PA435X,
whether activated by a REMOTE MASTER ON/OFF CONTROL (item #11) or from the rear panel AC
Line Power switch (item # 15).
15. Master AC LINE ON/OFF Switch. Turns power OFF to the entire PA435X, regardless of front panel
POWER switch conditions. Must be placed in the ON (I) position for the other power switching functions
to work.
