QSC ISA750 450W 8 Ohms Power Amplifier - Your Sound Solution for Every Event
The ISA Series is a cost-effective choice for sound contractors. It has four low impedance models (ISA 280, ISA 450, ISA 750, ISA 1350) designed for 2-ohm operation. With versatile loading options and a great feature set, it's perfect for any permanently installed sound system.
The ISA750 comes in a rugged 3-U chassis. It has rear panel gain controls for easy and secure operation, with 2 dB detents for quick and repeatable settings. Inputs include XLR and detachable Euro-style connectors. Outputs have covered barrier strip connectors for safety, and a DataPort V2 (Version 2) terminated with an HD-15 connector for use with DPV2-compatible signal processing accessories like the XC-3 Crossover, SF-3 Subwoofer Filter, LF-3 Low Frequency Filter, and the DSP-3 with external power supply.
Selectable high-pass filters protect speakers and prevent saturation with little impact on the sound. The ISA Series also has extra protection circuitry for DC, infrasonic, thermal overload, RF, and short circuit protection.
On the ISA 750, class H complementary bipolar output circuitry boosts system efficiency by reducing AC power draw and waste heat by 40%. Cooling is done by an automatic variable speed fan that pulls air from back to front.
