The church's Praise and Worship Team definitely needs a new power amplifier. In the middle of last Sunday's singing, the audio suddenly sounded as if a couple of live wires were rubbing with the audio fluctuating. One of the amps was grounded! There was nothing the sound man can do but uplug the offending power amplifier. After church, the sound man recommended that we set aside money for a new power amp. He recommended that the church purchase Boehringer EP4000 EuroPower power amp that is capable of delivering 2 x 2,000W at 2 ohms up to 4,000W at 4 ohms in bridge mode. According to the sound man, the power amp is capable of removing infra-sound frequencies. Of course no one in the meeting understood what the heck he was talking about. But we all said "yes" when we learned that the power amp was less than $300.
