Hifonics VULCAN VX690A Owner's Manual
The AUTO TURN ON switch determines the way how the sound system will be turned on. If you want to turn on the sound sys-

tem with the remote cable of the head unit and it's connected as described on page 5 Section #2, the switch must be in position
REM. If you need to switch the sound system automatically because your head unit does not have a remote cable, you can set
the switch AUTO TURN ON to DC OFFSET or AUTO.
By the so called DC OFFSET function the amplifier detacts a voltage increase to 6 volts on the high level speaker outputs and
turns on and the amplifier automatically. As soon as the head unit is turned off, the amplifier shuts down automatically.
The DC OFFSET function usually works with 90% of all headunits, because they are equipped with the "High Power" outputs.
Only with a few older headunits the AUTO TURN ON function is not applicable. Then use the switch position AUTO, which turns
the amplifier on and off with a little delay.
IMPORTANT: The AUTO TURN ON function works only with high level input operation. Refer to #5 and #9.
If the POWER LED lights up blue, the sound system is ready for operation. If the POWER LED lights up red refer to the chapter
