Schertler's Arpavox has been specially developed for harpists who want a professional amplification system that still enables the natural sound quality of the instrument to shine through. The Arpavox set comprises four RESOCOIL sensors, which are used to capture every nuance of this complex instrument, and an internal preamplifier. The preamp is powered by a 9V battery and enables phase switching between Resocoils, as well as gain regulation. The system is controlled via a volume sensitive potentiometer that can be placed inside one of the sound holes on the back of the harp.
Arpavox is designed for fixed installation inside the instrument and does not involve any modification to the harp itself. The Resocoils can be fixed using a simple adhesive (we suggest a single-component shoemaker's glue). The preamplifier can be attached with velcro (supplied with the Arpavox set).
The system enables players to perform on loud stages and still hear themselves while blending into the overall mix.
