8) AC POWER SOCKET Make sure the unit is grounded; all three terminals of the AC power plug must be connected to avoid any injury to the user
or damage to the unit.
DV Mark amps and combos are manufactured to be used in the country where they have been sold, and are factory preset to that country’s voltage.
So make sure you’re sending the correct voltage to your amp before you connect it
to AC power.
9) ON/OFF SWITCH This switch delivers AC power to the amp,
