II. Output parameters of Powerbox Mk2
Powerbox Мк2 can power both effects with low power consumption and effects
requiring more current or voltage. For this purpose, the outputs are divided in groups with
different options:
Outputs for effects with high power consumption
The first two groups – outputs 1 to 4 can deliver a maximum of 500 mA per group. This
means the total consumption for outputs 1 and 2 should not exceed 500 mA and the total
consumption for outputs 3 and 4 should not exceed 500 mA as well. Output voltage should be
chosen between two fixed voltages – 9V and 12V. These outputs are designed for supplying with
higher current consumption like delay pedals, processors, tube effects, loop systems, etc. They
are, of course, universal and you can power lower consumption effects too – chorus, tremolo,
compressor, distortion, overdrive, etc.
Outputs for effects with average power consumption
Use output 5 and 6. Maximum power consumption for this group is 250 mA, which means
that the total consumption for these two outputs should not exceed 250 mA. The output
voltage can be chosen between four fixed voltages – 9V, 12V, 15V and 18V. They are specially
designed for effects which require voltages up to 18V and can be used for any type of effects.
Outputs for effects with low power consumption
Outputs 7 to 10 in two galvanically split groups are specially provided for supplying with
low-consumption, noise-sensitive effects. Here the output current is fixed to 9.6V÷9.8V –
exactly the voltage of a new 9-volt battery. They are characterized by incredibly low noise and
have double filtering and stabilizing of the current. Maximum power consumption is 50 mA per
group. They are designed for use with effects like wah pedal, overdrive, distortion,
compressor, booster and the like.
III. Configuring output voltages of Powerbox Mk2
Changing the output voltages of Powerbox Mk2 is done with the help if a dip switch,
situated at the top of the device. Selectors can be switched while the device is either switched
on or off. Be careful when switching! Maximum output voltage of 18V can damage effects
which operate at lower voltage! Before making any changes on the output voltages, make sure
the effects can work with the desired voltage. Don’t forget the output voltage is changed for
the two outputs in the particular group. Check both effects when switching voltage. In order to
get 9V at each of the 10 outputs, all 4 switches have to be up:
9VDC
