QSC ISA450 2 channels, 260 watts/ch at 8Ω, 425 watts/ch at 4Ω, 700 watts/ch at 2Ω
The QSC ISA450 is, one of the ISA Installed System Amplifiers, professionally designed to meet the needs of the system contractors and designer all around the world. In this ISA system there are three models that features isolated 25, 70, and 100 volt outputs for distributed sound systems, while four low impedance models are rated for 2 ohm operation. The ISA Series is a rugged and cost-effective power solution, because of its comprehensive set of features and versatile loading options, for any permanently installed sound system. It is the QSC ISA450 2 channels, 260 watts/ch at 8Ω, 425 watts/ch at 4Ω, 700 watts/ch at 2Ω.
Features
- 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 (30 Hz or 70 Hz) protect speakers and prevent speaker transformer saturation with minimal effect on program material
- Front panel LED 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
