The amplifi er is stable into any load which does not dip below 0.5 ohms, but it will
protect itself by shutting off any channel which outputs more than 10 amps (200 watts
peak into 2 ohms). The protection circuit is reset by turning the amp off for a few
moments and then turning it back on. We recommend that you check your output
wiring and/or the loudspeaker if this happens, and contact your dealer or the factory
if you have problems.
The Furutech binding posts deserve special note - in keeping with the requirements of
Class 2 circuits in North America they are fully insulated. Speaker cables connected
as intended will have no exposed conductive metal. The Furutech posts accept
banana, spade, bare wire or pins with a diameter of 4.5mm or less. Bare wire, pins
and spades socket into the binding post only from the bottom. The nuts on the
binding posts should only be fi nger tight. Never tighten with wrench or pliers.
NOTE - The Audio outputs of power amplifi ers are considered class 2 (CL2) circuits in
North America. This means that the wire connected between the amplifi er and the
speaker(s) shall be rated at minimum Class 2 (CL2) and shall be installed according
the U.S, National Electrical Code (NEC) Article 725 or Canadian Electrical Code (CEC)
section 16.
Operation:
Once the speakers have been connected in observation of the proper regulations
and with the observation of polarity and phase you may attach the input cables and
power cord. It is always advised that the power cord is the last connection made
and the fi rst to be removed.
You are now ready to play music. Turn the level at the source or preamp to a low
level. Press the power switch on the front panel of the XA25, the blue LED above the
power switch will light. Turn the volume up to your preferred listening level. Sit back
and enjoy! The XA25 takes approximately an hour to fully warm up and sounds better
as it does. Pushing the power button on the front panel of the XA25 a second time
turns it off and extinguishes the blue LED.
