Overview
For system integrators and sound contractors, the QSC ISA280 commercial power amplifier provides dependable, cost-effective power for permanent installations, security paging, and surveillance audio systems. The ISA280 delivers 830W of continuous output and supports low-impedance 2-ohm operation so you can drive challenging speaker loads without adding extra equipment. With a focused frequency response down to 50 Hz and up to 20 kHz and low THD, the amp preserves speech intelligibility and program clarity—critical for monitoring, paging and life-safety audio.
Designed for long-term reliability, the ISA280 includes comprehensive protection circuitry (DC, thermal, short-circuit), covered output connectors for agency compliance, and a quiet variable-speed fan that only ramps up when needed. Front-panel signal, clip and power indicators plus rear gain trims make rack commissioning fast and repeatable. Backed by a 3-year limited warranty, it’s an ideal choice for pro audio, security, and surveillance integrators specifying dependable amplification for commercial buildings, campuses or control rooms. Contact your sales rep to spec the QSC ISA280 for your next installation or order now to secure reliable system power.
