Details
The QSC ISA500Ti 2 Channel Power Amplifier is 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. 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
Features
- Low-impedance outputs plus isolated 25, 70, and 100 volt outputs for distributed audio systems
- Rear panel gain controls for tamper resistance; 2-dB detents allow 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 (50 Hz or 75 Hz) protect speakers and prevent speaker transformer saturation
- Front panel indicators include power, signal, and clip
- Covered barrier strip output connectors for safety agency compliance
- Automatic on-demand variable-speed fan: quiet normal operation, with maximum cooling when needed
- Rear-to-front air flow helps keep 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
