9 How to Operate the ICON
•
Power On, Stand-by and Off
Rotate the POWER switch to the ON position and sound will be heard from the Loudspeakers when the tubes have
reached their operating temperature. The amount of time it takes is dependent upon the temperature of the Tubes
(about 3 min - smooth increment of heating voltage). Rotate the POWER Switch to the OFF position to stop amplifying
the audio signal. Refer to figure 12.
Standby Mode:
The ICON amplifier SHOULD NOT BE LEFT RUNNING WHEN NOT IN USE. Unlike solid state amplifiers, tube
amplifiers should be shut down when not being used . This will greatly prolong tube life. A standby mode has been
provided for short-term use between listening sessions so that the amp will remain in a “warmed up“ state. If you will
not be listening to the amplifier for more than an hour, it is advised that the amplifier be turned off. The standby switch
lowers the voltage on the tubes and heater filaments to ½ of normal operating voltage. Some output (distorted) will be
heard so the source material should be turned off when in standby mode.
