Important - Magenta Margules SF220 BLACK EDITION Manual De Instrucciones

OPERATION (CONT):
To minimize unwanted noise or interference in the system:
1.- Avoid excessive length in the interconnection cables.
2.- Avoid having the cables near the alternating current line.
3.- Avoid ground feedback loops between components.
4.- Interconnect cables must be shielded and in good condition.
Burn-In Process:
About 150 hours of music playback are required. Having the unit on without music does not work for proper burn-in.
Vacuum Tube durability:
We recommend changing both vacuum tubes every three years for optimal performance, although they may last a more
extended period.
Type of compatible tubes or valves:
The unit has 12AU7 tubes or the ECC83 equivalency, do not use any other type of tube.
IMPORTANT: Never remove the tubes from the circuit while the equipment is connected to the power outlet.
The unit has an AC outlet for associated equipment interrupted with a capacity of 15 amps, so you will be able to control the on
and off of the equipment connected to the SF 220.
It is usual for the input indicator to be lit while the unit is connected to the power supply.
If a sudden power loss causing two or more selection indicators to light, unplug the unit from the power outlet and redo the
initialization procedure (p. 15).
The unit's power cord can be exchanged for higher quality to improve the tonal characteristics.
TROUBLESHOOTING:
The equipment does not turn on:
Check that the power supply is correct and that the power cord is connected to a live electrical outlet.
There is no sound:
The selector light is on, but there is no sound: Ensure the unit is turned on by checking the light in the upper left corner. Check
that the input signal is connected to the correct input.
Check the cable between the OUT 1 output and the power amplifier, make sure that the amplifier is tured on and ready to
operate.
If more than one indicator is lit:
A transient in the electrical current caused an error in the remote control logic.
Restart the unit by unplugging it from power and plugging it in again.
