The Schertler STAT-PRE preamplifier is the perfect complement to the STAT series of sensors for stringed instruments in the orchestra, as well as a useful and practical solution for other compatible active microphones such as electret microphones. Compact and easy to use, the STAT-PRE guarantees a faithful reproduction of the instrument's sound while providing up to 500 hours of playing time on a single 9V battery. The STAT PRE's sturdy aluminum case allows it to be placed on the floor without risk of breakage, or attached to the belt of the pants via the optional PRE CLIP accessory. STAT PRE is the integrated preamplifier in all STAT-SETs.
