The church I work at hired a consultant to redesign the sound system. Gentleman did a fantastic job and really knows his stuff. However, one item keeps driving me crazy because it doesn't make sense. For the lobby there was an existing 70v system. He had me remove the transformers from the amplifier and connect the speakers directly to the mono bridge out (didn't change anything else, so the speakers are still all 70v wired in parallel). When I questioned it, his response was that the amp was powerful enough. Has anyone heard of doing this?
