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.
