Product Overview

Designed as a cost-effective solution specifically for sound contractors, QSC's ISA Series features seven models including four low impedance models (ISA 280, ISA 450, ISA 750, ISA 1350) rated for 2 Ω operation, and three "Ti" versions with isolated 25, 70 and 100 volt outputs for distributed audio systems (ISA 300Ti, ISA 500Ti, ISA 800Ti). Versatile loading options and a comprehensive feature set make the ISA Series a rugged, cost-effective power solution for any permanently installed sound system.

Housed in a rugged 3U chassis, the ISA450 features rear panel gain controls for tamper resistant operation with 2 dB detents for quick and repeatable settings. Inputs include both XLR and detachable Euro-style connectors. Outputs feature covered barrier strip connectors for safety agency compliance, and for added versatility, a DataPort V2 terminated with an HD-15 connector is provided for use with DPV2-compatible signal processing accessories. Plus, selectable high-pass filters are included to protect speakers and prevent speaker transformer saturation with minimal effect on program material.

Features

  • 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/DSP-4 (with external power supply)
  • Independent defeatable clip limiters for reduced distortion
  • Selectable high-pass filters protect speakers and prevent speaker transformer saturation with minimal effect on program material
  • Front panel indicators include power, signal, and clip
  • Stereo, Bridge, or Parallel operating modes
  • Comprehensive protection circuitry including DC, infrasonic, thermal overload and short circuit protection
  • 3-year warranty plus optional 3-year extended service contract
