Setup:
The XA25 measures 17”w x 17.4”d x 6”h and weighs 45 pounds. You may place it
wherever you please, but not directly on carpet - it is going to need lots of free air for
adequate cooling. There needs to be space above and unobstructed space around
the sides to allow for proper air fl ow. This is a factor in reliable operation and long life.
The XA25 is expected to have a 25-degree C rise at the sinks when running. Under
normal operation you should be able to grasp the heat-sinks for 5 to 10 seconds
without heat being an issue. If the amplifi er becomes too hot to touch please
contact your dealer or the factory for assistance.
AC power is provided by a conventional detachable IEC 320 grounded AC mains
power cord. This power cord serves as the safety disconnect. The power cord should
be removed from the wall in the event of electrical storms or when the XA25 is not
going to be used for long periods.
The amplifi er is designed to perform well with the included power cord. Should you
select an “after market” detachable power cord, please confi ne your selection to
those rated by local authorities to carry a minimum of 13A at 250V.
At idle the XA25 will consume 240W from the AC mains. The required voltage and
correct fuse value will be indicated on the rear of the amplifi er. Both 100 Vac and 120
Vac builds are fused at 5A. The 220 - 240 Vac build amplifi ers are fused at 2.5 amp.
Input Connection:
The XA25 accepts a single ended (RCA / Cinch) input connector. The input
impedance is 47 Kohm making the XA25 compatible with either tube or solid state line
stage pre-amplifi ers or source components with a built-in volume control.
Output Connection and Loudspeakers:
The rear of the XA25 is equipped with a pair of Furutech binding posts for each
channel, four total. The binding posts are marked red and black. The Red output
connector connects to the Red (+) of your speakers and the Black connector will
connect to the Black (-). The Black output connector is at circuit ground. You can use
it to connect to powered sub-woofers if you like.
