QSC ISA750 Power Amplifier , แอมป์ , amplifier, power amp, power amplifier

Features:

• Four models for low-impedance applications
• 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)
• 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
• 3-year warranty plus optional 3-year extended service contract
