100V line amplifiers

100V line amplifiers (also known as constant voltage amplifiers) are specially designed audio amplifiers used in public address (PA) and commercial audio systems. Instead of delivering audio at standard speaker-level voltages, they transmit audio signals at a constant voltage (typically 100V, sometimes 70V), allowing efficient distribution of audio over long cable runs to multiple loudspeakers with minimal loss and simpler wiring.
