QSC Audio Products, Inc.
Designed as a cost-effective solution specifically for sound contractors, the ISA Series features six models including three low impedance models (ISA 280, ISA 450, ISA 750) rated for 2-ohm operation, and three "T" versions with 25, 70 and 100 volt outputs for distributed audio systems (ISA 300T, ISA 500T, ISA 800T). Versatile loading options and a comprehensive feature set make the ISA Series a rugged, cost-effective power solution for any permanently installed sound system.
Rear panel gain controls for tamper resistant operation with 2-dB detents for quick and repeatable settings
XLR and detachable Euro style input connectors
DataPort V2 for use with DPV2-compatible signal processing accessories (XC-3, SF-3, LF-3) and DSP-3 (with external power supply)
Independent defeatable clip limiters for reduced distortion
Selectable high-pass filters that protect speakers and prevent speaker transformer saturation with minimal effect on program material
Class H complementary bipolar output circuitry reduces AC power draw and waste heat by 40%
Front panel indicators include power, signal, and clip
Covered barrier strip output connectors for safety agency compliance
Automatic variable-speed fan for quiet normal operation with maximum cooling on demand
Rear-to-front air flow keeps equipment racks cool
Stereo, Bridge, or Parallel operating modes
Comprehensive protection circuitry including DC, infrasonic, thermal overload, and short circuit protection
