Hall AMP-7040 Compact Stereo to Mono Audio Amplifier with RS-232 Control

Deliver clear, controllable audio to any distributed system with the Hall Technologies AMP-7040 pro amplifier. This compact stereo-to-mono amplifier converts two line inputs into a focused 40W mono output with switchable 70V/100V capability, making it ideal for paging, public address, security and surveillance monitoring installations where intelligible voice and background music matter. Energy-efficient Class D amplification keeps operating costs low, while a full-featured input section accepts two stereo line sources plus a balanced microphone input with 48V phantom power for condenser mics or wireless receivers. Integrated mixing, EQ and a mono-sum function let you prioritize speech clarity in classrooms, boardrooms, retail or control-room environments. Control is simple and scalable: local front-panel buttons and IR remote access combine with RS-232 addressing (up to 16 amps from one port) for centralized AV and security system management. With a 20 Hz–20 kHz frequency response and robust build quality, the AMP-7040 delivers dependable audio performance for monitoring, paging and pro AV installations.
