21) SERVICE
The ATCS (Advanced Tube Control System) allows users or service technicians to connect this port to the optional DV
Controller interface, for collecting technical data and tube parameters from the amp.
22) AC POWER SOCKET
Make sure the unit is grounded; all three terminals of the AC power cord 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.
