Proficient PAS-A4100 4-Channel Analog Filtering Amplifier, 100W

Deliver consistent, adaptable power for distributed audio, AV and security monitoring applications with the Proficient PAS-A4100 4-Channel Analog Filtering Amplifier. Built as a single rack-mount chassis, this amplifier provides up to 100W per channel into 8 ohms across a wide 20Hz–20kHz frequency range, giving installers reliable headroom for background music, paging, surveillance audio and security system playback. Each of the four independent channels includes two selectable analog high-pass filters—an intuitive way to protect satellite speakers or tailor crossover behavior for subwoofers without the complexity of DSP or IP-based control. The PAS-A4100 is bridgeable in pairs for higher output where needed and is stable at low impedances so a single channel can power multiple fixtures. Independent gain trims, per-channel preamp outputs and audio-sensing/trigger capabilities reduce setup time and simplify integration with control systems. Rugged front-panel indicators and built-in protection circuitry make ongoing monitoring and troubleshooting fast for installers and service teams. Ideal for commercial AV, security and surveillance audio zones—specify the PAS-A4100 for reliable, easy-to-deploy multi-zone amplification.

• Flexible 4-channel design with pair-bridging lets you configure 2, 3 or 4-channel systems to match room layouts and scale power where you need it
• Selectable analog high-pass filters per channel protect satellite speakers and optimize subwoofer integration without DSP or network configuration
• Independent level controls and preamp outputs streamline system tuning and make integration with processors, mixers or secondary amps effortless
• Stable at low impedance to drive multiple satellite speakers or subwoofers from a single channel for efficient distributed audio and paging systems
• Front-panel signal, clipping and protection indicators plus audio-sensing and trigger inputs simplify monitoring, troubleshooting and power management in commercial installs
