XA60 Owner’s Manual
Now that the source component is connected, make sure there is no
signal coming from it, probably by turning the volume all the way
down.
With the speakers connected, make sure the power cord is attached
and plugged into mains power; toggle the front panel switch to activate
the amplifier. The “Power” LED will come on.
Do everybody a favor and try not to have shorted output cables. It
happens accidentally all the time, and the amplifier is designed to
survive, but why tempt fate. If you accidentally cause the fuse to
open, it must be replaced with a like rated fuse before the amplifier will
operate. Please remove the amplifiers power cord from the wall outlet
before replacing this fuse. The fault, which caused the “open”, will
need to be corrected prior to replacing this fuse.
Of course it’s always possible that something may go wrong. If so,
don’t get excited. It’s really aggravating when a product doesn’t work,
we understand, but it will get fixed. We go to a lot of trouble to make
products reliable, and the failure rate of our product is very low. This
is small comfort to the few, but take it easy and give us a call if you
have problems.
People are interested in how long it takes for these amplifiers to break
in. Depending on the resolution of the rest of your audio chain,
you may or may not notice any break in of the XA60 beyond the
first 50 hours of operation. You will likely notice the difference in
sonic character between cold and normal operating temperature, so
we recommend letting these amplifiers warm up before any serious
listening.
It takes about an hour for them to completely warm up, and this is
where we adjust them first. Then we adjust them again and again over
a couple of days, keeping the bias and offset in the sweet spot. Our
environment is about 23 degrees Centigrade, room temperature, and
the heat sinks will rise to about 25 degrees C. above that, for a heat
sink temperature of about 48 degrees C. This is where they habitually
operate at their sonic best.
In your setup the heatsink temperature may vary a bit due to the
normal regional variance in line voltage and ventilation, but it is not
