OPERATION:
When your SF 220 is connected for the first time, it is necessary to initialize the system, this is done by pressing the input
selector button.
Check that the volume is at the minimum level to avoid a sudden bump of sound that could damage your speakers.
As long as the SF 220 is connected to the electrical supply network, the valves´or vacuum tube´s filaments will always be
working, so the ignition will be immediate. The life expectancy of the valves or vacuum tubes does not decrease due to this
fact, instead it increases since the electronic cloud of the cathode is already formed when the high voltage is applied (when
it is turned on).
Turn on the equipment using the power switch on the remote control or the front of the equipment. If the power supply is
interrupted, allow the bulbs' filaments to heat up for a few seconds.
Select the input source by pressing the selector switch on the front panel or the remote control unit. This will turn on the blue
light on the front panel indicating the selected source.
The blue light below the vacuum tubes indicates that the unit is active. Now the high voltage the preamplifier is operational.
General Comments:
The unit is always warm, so it should be placed in a ventilated area, with at least one inch of air on the top and sides of the
equipment, to allow airflow and avoid overheating.
Always place your unit on a firm platform to avoid external vibrations, or that can impront an unwanted tonal character.
You can alter the tonal characteristics by placing the unit on different types of stands such as rubber feet, spikes, etc.
