QSC ISA-1350

The ISA Installed System Amplifiers are designed to meet the needs of sound system designers and contractors worldwide. Three models feature isolated 25, 70, and 100 volt outputs for distributed sound systems, while four low impedance models are rated for 2 ohm operation. The ISA 1350 drives 70 volt lines directly with 1500 watts per channel. Versatile loading options and a comprehensive set of features make the ISA Series a rugged, cost-effective power solution for any permanently installed sound system.

Features

• Four models for low impedance applications
• ISA1350 drives 70 volt lines directly with 1500 watts per channel
• Three "Ti" versions include low impedance and isolated 25, 70, and 100 volt outputs for distributed audio systems
• ISA450 and ISA750: THX™ approved for professional cinema applications
• 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 (30 Hz or 70 Hz on non-"Ti" models, 50 Hz or 75 Hz on "Ti" models)
• Class H complementary bipolar output circuitry reduces AC power draw and waste heat by 40% on ISA750 and ISA800Ti, and by 50% on ISA1350
• Front panel indicators include power, signal, and clip (and protect on ISA1350)
• 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
• 3 year warranty plus optional 3 year extended service contract

"Ti" Models

• Isolated 25, 70, 100 volt, and low impedance outputs available simultaneously
• Simple barrier strip connection determines output mode
• "Ti" models have fully isolated 25, 70, and 100 volt outputs
