check the specifications of your speakers. Speakers with 6 ohms up to 8
ohms impedance should be connected to the “8 ohm” speaker connectors.
Genesis loudspeakers should be connected to the “4 ohm” connectors.
Two sets of 5-way insulated binding posts are provided on the rear of your
amplifier, but we recommend that you use spade lugs or banana plugs
instead of bare wire. Make sure that your speaker cables are firmly
connected to the correct speaker connections. Loose or wrong connection of
the cables or speakers may cause damage to the power output tubes.
DO
NOT SHORT THE TERMINALS TOGETHER.
Do not run the amplifier without speakers connected.
This
will damage the output transformers.
Source Input Connection
Use high quality interconnects to connect the source components
to your amplifier. All the internal input connections are high
quality with shielded silver solid core wiring internally. They are
labeled “Tape”, “CD”, “Tuner” and “Aux” for convenience. You
can use any input for any device.
Operating and Adjustment
Make sure that your amplifier is properly connected to a high-current power
receptacle. Before you turn the amplifier on, check that the speaker
connections are properly hooked up and tightened. Turn the volume control
to minimum (fully anti-clockwise), and turn the power switch to ON. The blue
LED will light up to indicate that the amplifier is working. In a few seconds,
you will hear a faint click to indicate that the soft-start circuit has engaged
and the vacuum tubes will begin to glow a soft, warm orange color.
Give your amplifier a warm-up period of at least a minute for the valves to
stabilize before attempting to play any music. It should take less than 10
minutes to fully warm up the tubes. Because of the fast warm-up power
supply, you will get 95% of the maximum sonic quality within 5 minutes of
turn-on.
Do not leave your amplifier turned on 24 hours a day 7 days a week. Turn on
the amplifier only when you intend to use it.
While a pair of KT88’s will pump out up to 75 watts, the I60 is biased very
conservatively for a longer lifecycle on the power tubes, and also more
musicality. In normal usage of around 500hours per year, the power tubes
should last 6 to 8 years. The preamplifier tubes, and the driver tubes should
easily last twice to three times that. Military-spec tubes are used extensively
