Basic operation

The harpē is pretty strait forward. There are no mechanical adjustments or tuning required. It is the electric sharks version of a plug-in and play machine. That being said it’s not quite like anything else. Here are some tips to get started.

Operation voltage

The harpē has a pretty standard operation voltage between about 5 and 10 V. The startup speed is dependent on how much tension your cartridges have. It can range anywhere from 6.5 to 7.5V. It loves jumpstart if you were power supply or battery pack is capable of it. If you’re trying to run your machine out a lower voltage you can kick off the cam with your thumb and start rocking and rolling.

The voltage you decide to use depends on your hand speed. This should not change much depending on your needle groupings. One of the magic things about this machine is it’s dynamic give. When using the end of the needle with its 4.1 mm stroke you get a very light hit good for small groupings. As your groupings increase sizes simply push deeper, rather than turning up the voltage. This gives you a stiffer and stiffer hit. This machine is good up to about 14 liners without slowing your hands speed down and mags of all common sizes

When you first use this machine, it’s good to start at a slow speed gradually building until you find the spot that works best for you. I run it around 7.4 and find that most artist are in the 7 to 8 V range for most operations.
