คุณสมบัติ
- 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
- 3-year warranty plus optional 3-year extended service contract
"Ti" Models
- 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
