VI. Connecting effects to Powerbox Mk2
Powerbox Mk2 is designed to follow the natural order of effect pedals in the
pedalboard. The normal order is from right to left after the guitar. Most often you find first
effects like wah pedal, booster, compressor, overdrive, distortion and others. After that -
phaser, chorus, flanger, delay, etc. In most cases, the effects in the group immediately after
the guitar are analogue, and in order to work, they need a comparatively low current, which
rarely exceeds 10mA. The next group of effects includes pedals like delay, which consume
about 100mA. This is the reason why effects with lower power consumption are situated on the
right, and others – on the left.
For proper connection of all effects and minimizing ground loop problems and to reduce
unnecessary loading of PowerboxMk2, it is good to comply with some recommendations. Refer
to all user manuals of all your effects. Write down the power supply voltage and the needed
current for each effect and put them in descending order according to the maximum current
consumption.
Effects with high power consumption – e.g. 350mA, should be powered from one of the first
outputs of Powerbox Mk2, and it is recommended to leave the other output of the
corresponding group unused.
You can combine several effects which require voltage different than 9V in one group. It is
better if they have similar current consumption.
Positive ground effects must be in a separate group.
Avoid combining two effects with high and low power consumption, for example delay and
overdrive in the same group.
Remember: Connecting effects to a combined power block must be well considered. If
you think you can’t do it on your own, don’t hesitate to contact us and we can prepare an
optimal scheme of connection of all your effects, free of charge. All you need to do is send the
brands and models of your effects to

. We will get back to you as
soon as possible!
VII. Plugging Powerbox Mk2 in the electricity
Powerbox Mk2 is designed with a standard 50/60Hz transformer. It is pre-configured to
work at either 220V or 110V. You should be aware that the power supply should not be
changed. You cannot operate a 110V Pedal Power using 220V power without the correct step
down transformer. If for any reason short a circuit occurs and none of the LEDs works, it is
most likely the fuse has blown. It is located at the lower part of the mains socket and can be
easily replaced. First, unplug the power supply cable, and with the help of a screwdriver pull
out the fuse. Replace it with a new one. You don’t have to search for a new one at the
moment; there is a spare one in there. In this way, you will be sure that in case you need one,
you have it at hand. Powerbox Mk2 works with a standard 20x5 fuse. At 220V use 200mA fuse,
at 110V – 400mA.
VIII. What effects Powerbox Mk2 can’t power?
You can’t power effects working with alternating current (AC) – for example Digitech
Whammy, and effects which require voltage or stronger current higher than the maximum for
the device. You have to check the manuals for your effects whether they are compatible
with Powerbox Mk2!
