pressed in, the power tubes work in High Bias mode; when the button is depressed, they work in Low Bias mode.
In Low Bias mode, the tubes use less power and less ‘tube life’ is taken out of them. High Bias mode gives top quality and power, and higher-
fidelity sound—but the power consumption and dissipation of the tubes increases. In either mode, unlike other tube amplifiers, the Bad Boy
120 / Triple 6 is able to greatly prolong the life of its tubes by keeping them optimally biased at all times.
21) SERVICE
The optional ATCS (Advanced Tube Control System) interface allows users or service technicians to connect this port to a
computer and, with dedicated software, collect 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.
