XA200.5 Owner’s Manual
So the amplifier is sitting there unconnected.
Make sure that the rear panel power switch/breaker is off  (down).  
Plug the AC cord into the back of  the amplifier, and then into the 
wall.  Then turn the power switch/breaker on (up).  The lights in 
your house will dim for a moment as the power supply charges the 
capacitors.  
If  your amplifier uses a circuit breaker and not a fuse, please note 
that this circuit breaker is not a “safety device” or “emergency 
disconnect” for this product.  It will provide current limiting which 
will protect the amplifier, but it does not provide personal shock 
protection in the manner of  a ground-fault interrupter.  One more 
reason why it is important not to defeat the Earth connection of  
your power cord.
On the front panel, the “Standby” LED indicator should be glowing 
blue, indicating that AC power is available and the capacitor banks 
are charged.  If  the “Power” LEDs are lighting the meter, use the 
front panel stand-by button to go to stand-by mode.
Now turn off  the rear power switch and unplug the AC power cord 
from the wall while you connect the speakers and inputs.
Check to make certain that the loudspeaker cables aren’t shorted at 
the loudspeaker end,  connect speaker cables to the output binding 
posts on the amplifiers, observing correct polarity.  The output 
binding posts will accept either bare wire or spades.  (Regulatory 
agencies in many countries have banned binding posts that will 
accept a banana plug, forcing us to abandon this option.)  Make sure 
that your speaker wires only attach to the outputs of  the amplifier, 
not to each other and never to the amplifier case.  
Remember the warning about treating the output connections as 
ground, particularly if  you are using a powered subwoofer with this 
amplifier.  If  you need a ground, use the one provided specifically on 
the rear panel of  the amplifier.
The amplifier may be driven single-end or balanced, your choice.  
Single-ended input will always occur through the RCA connector and 
balanced input will always occur through the XLR connector.  
Again, if  you drive the amplifier single-ended then leave the supplied 
jumpers in place between pins 1 & 3 on the input XLR.  
On the XLR connector pin 1 is ground, pin two is positive input and
