Musicians often asked us for a system for acoustic instruments that provides AER sound and quality everywhere… independent from the mains. This is exactly what the Compact mobile has been developed for. Based on the Compact 60, thus identical in sound, but with adapted technology and slightly changed dimensions you can play without the mains for three to four hours. Whether you chose to play in the old town or on a glacier, the sound is always clear and omnipresent. In case of insufficient battery power the intelligent power control gives a warning and saves you from lack of power during performance. Moreover it prevents the batteries from being completely exhausted.
