Figure 7. Class B Wiring 

Continued on next page

 

Amplifier Field Wiring, 

Continued 

Class B Wiring 

 

Leave the 10 K, ½ W resistors 
(378-030; brown/black/orange) on 
the “B+” to “B-” terminals of 
unused circuits. 

 

All wiring is between 18 AWG 
(0.8231 mm

2

) and 12 AWG  

(3.309 mm

2

). 

 

Field wiring is supervised and 
power-limited. 

 

Total available Flex-50 power is 
50 W (2A @ 25 VRMS, 0.707A @ 
70.7 VRMS).  

 

Total available Flex-35 power is 
35 W (1.4A @ 25VRMS, 0.5A @ 
70.7 VRMS).  

 

NACs and power stages can be 
configured for any combination of 
circuits as long as the total output 
power does not exceed the 
maximum specified rating.  

Flex-35 Examples: 

 

25 W to PS1 + 10 W to PS2  
0 W to PS1 + 35 W to PS2* 

Flex-50 Examples:

 

25 W to PS1 + 2 5W to PS2  
40 W to PS1 + 10 W to PS2 
*This is an example of a self-
backing configuration.  PS1 is not 
loaded, but is saved for backup 
should PS2 fail. 

 

Terminal designations “+” and “-” 
are for the alarm state. 

 

Shields, when required, are 
normally connected to 0 V as 
shown. Alternate shield 
termination using Earth ground is 
provided on the amplifier chassis.
