PRO is a four-channel preamp-system for hurdy-gurdies.

Melody-strings, trompette, drones and sympathetic strings are engineered as discrete balanced outputs in a tough metal box. The volumes are controlled by faders located on the instrument.
In addition the mix of these four channels is provided as a fifth balanced (XLR) and unbalanced (RCA) output. This allows both, a one channel setup or a four channel mode with an additional line for effects or an electronic tuner.
