Four models for low-impedance applications
ISA 1350 drives 70V lines directly with 1500 watts / channel
Three "Ti" versions include low-impedance and isolated 25, 70, and 100 volt outputs for distributed audio systems
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 ISA 750 and 800Ti, and by 50% on ISA 1350
Front panel indicators include power, signal, and clip (and protect on ISA 1350)
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
