Input Connection
The INT-25 accepts three (3) single ended (RCA / Cinch) input connector. The input
impedance is 48 Kohm making the INT-25 compatible with either tube or solid state
source components.
Output Connections and Loudspeakers
The rear of the INT-25 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.
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.
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. Once you turn on the AC from the rear switch, the amp
will come on breifl y and go into Standby.
You are now ready to play music. Press the power switch on the front panel of the
INT-25, the display will light up. Select the input you want from the front panel or
remote. Turn the volume up to your preferred listening level. Sit back and enjoy! The
INT-25 takes approximately an hour to fully warm up and sounds better as it does.
Pushing the power button on the front panel of the INT-25 a second time turns it off.
