Overview
Built for contractors and systems integrators who need dependable power for installed audio, the QSC ISA450 commercial power amplifier delivers punchy, professional performance for AV, security and surveillance installations. This QSC pro amplifier provides 1400W of continuous output with low-impedance 2-ohm capability so you can confidently drive challenging speaker loads and long line runs without compromising headroom. With a clean frequency range down to 50Hz and a maximum of 20kHz, the ISA450 maintains intelligible paging, monitoring and background music with just 1% THD under typical use.
Designed for real-world installations, the ISA450 includes comprehensive protection circuitry (DC, infrasonic, thermal and short-circuit), covered barrier strip connectors for safety compliance, and an automatic variable-speed fan that keeps racks cool while minimizing noise. Flexible operating modes (stereo, bridge, parallel) and standard XLR/Euro-style inputs speed deployment across commercial, cinema, security and surveillance projects.
Specify the ISA450 when you need a cost-effective, durable power amplifier for permanent installations—contact our sales team or add to your quote for your next security, monitoring or installed audio system.
